A bruise may appear hours after injury to the tissues below the skin's surface or in some instances, a bruise appears instantly when a blood vessel is breached such as during the injection process. Red blood cells extravasate into the surrounding tissue, and breakdown of these cells by macrophages results in loss of oxygen, giving the red blood cells a bluish hue. The byproducts of hemoglobin breakdown (heme, biliverdin, bilirubin, and hemosiderin) transmit the different colors to the skin that slowly resolve once these pigments are absorbed by the macrophages and digested. Due to the negative aesthetics of the skin discoloration that can occur for multiple days, there is a need for resolving the bruising process more quickly.
Described herein are compositions and methods for improving bruising. In some instances, the bruising is caused by an injection. Compositions and methods as described herein can improve bruising by improving macrophage function. Compositions and methods as described herein may further stimulate elastin and/or collagen production, intrinsic hyaluronic acid production, adipogenesis, or reduce inflammation.
Efficacy of an active ingredient depends on several factors including its bioavailability. For topical compositions, skin penetration ability is important for bioavailability of the active ingredient. Some methods for improving skin penetration and bioavailability can be too aggressive such as methods employing a skin barrier disrupter like an alcohol. Delivery systems employing liposomes may improve delivery and skin penetration of topical compositions in a safe and efficacious manner. Described herein are liposomal compositions for improved distribution, efficacy, bioavailability, and/or activity. Liposomal compositions may improve distribution, efficacy, bioavailability, and/or activity by improving delivery and skin penetration.

Bentonite clays can be employed in conjunction with the peptides to provide impart penetration and adsorption properties to the compositions, and can aid in stabilizing emulsions. Other clays, such as hectorite and magnesium aluminum silicate can also be employed. Bentonite or other clays can be modified to yield an organic modified clay compound. Salts (e.g., quaternary ammonium salts) of fatty acids (e.g., hydrogenated fatty acids) can be reacted with hectorite or other clays. As provided herein, fatty acids are referred to and described using conventional nomenclature as is employed by one of skill in the art. A saturated fatty acid includes no carbon-carbon double bonds. An unsaturated fatty acid includes at least one carbon-carbon double bond. A monounsaturated fatty acid includes only one carbon-carbon double bond. A polyunsaturated fatty acid includes two or more carbon-carbon double bonds. Double bonds in fatty acids are generally cis; however, trans double bonds are also possible. The position of double bonds can be indicated by Δn, where n indicates the lower numbered carbon of each pair of double-bonded carbon atoms. A shorthand notation specifying total # carbons: # double bonds, Δdouble bond positions can be employed. For example, 20:4Δ5,8,11,14 refers to a fatty acid having 20 carbon atoms and four double bonds, with the double bonds situated between the 5 and 6 carbon atom, the 8 and 9 carbon atom, the 11 and 12 carbon atom, and the 14 and 15 carbon atom, with carbon atom 1 being the carbon of the carboxylic acid group. Stearate (octadecanoate) is a saturated fatty acid. Oleate (cis-Δ9-octadecenoate) is a monounsaturated fatty acid, linolenate (all-cis-Δ9,12,15-octadecatrienoate) is a polyunsaturated fatty acid. Fatty acids suitable for use can comprise from 5 to 30 carbon atoms, e.g., 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, or 30 carbon atoms.

The compositions for topical administration comprise the peptide compositions as described herein and a dermatologically acceptable vehicle. The vehicle may be aqueous or nonaqueous. The dermatologically acceptable vehicle used in the topical composition may be in the form of a lotion, a gel, an ointment, a liquid, a cream, or an emulsion. If the vehicle is an emulsion, the emulsion may have a continuous aqueous phase and a discontinuous nonaqueous or oil phase (oil-in-water emulsion), or a continuous nonaqueous or oil phase and a discontinuous aqueous phase (water-in-oil emulsion). When administered topically in liquid or gel form, a liquid carrier such as water, petroleum, oils of animal or plant origin such as peanut oil, mineral oil, soybean oil, or sesame oil, or synthetic oils can be added to the active ingredient(s). Physiological saline solution, dextrose, or other saccharide solution, or glycols such as ethylene glycol, propylene glycol, or polyethylene glycol are also suitable liquid carriers. The pharmaceutical compositions can also be in the form of oil-in-water emulsions. The oily phase can be a vegetable oil, such as olive or arachis oil, a mineral oil such as liquid paraffin, or a mixture thereof. Suitable emulsifying agents include naturally-occurring gums such as gum acacia and gum tragacanth, naturally occurring phosphatides, such as soybean lecithin, esters or partial esters derived from fatty acids and hexitol anhydrides, such as sorbitan mono-oleate, and condensation products of these partial esters with ethylene oxide, such as polyoxyethylene sorbitan mono-oleate. The emulsions can also contain coloring and scenting agents.
In certain embodiments, a silicone elastomer (e.g., dimethicone crosspolymer) is employed to increase delivery and penetration of the peptides into the skin. An alternative to increasing molecular weight (as with silicone gums) or adding filler (as with silicone compounds) is to partially crosslink siloxane polymers and disperse this material in an appropriate silicone carrier fluid. The resulting dimethicone crosspolymers (also known as silicone elastomers in the personal care industry) differ from basic polydimethylsiloxane (PDMS) because of the cross-linking between the linear polymers. These materials can be employed in peptide compositions, and also offer benefits in scar treatment, periwound protection and enzyme delivery. In skin care applications, the aesthetics of silicone elastomers (including those with functional groups) and their ability to absorb various oils (e.g., with a dimethicone/vinyl dimethicone crosspolymer such as Dow Corning® 9506 Elastomer Powder) are two of the elastomer's desirable properties. Silicone elastomers have a skin feel different from any of the silicone fluids, described as “smooth,” “velvety,” and “powdery.” It can be modified by controlling the amount of liquid phase in the formula, and therefore the degree of swelling. Due to their film-forming properties, dimethicone crosspolymers can be used as delivery systems for active ingredients such as the peptides described herein, or other composition components such as oil-soluble vitamins and sunscreens. Sunscreens such as octyl methoxycinnamate can be more efficiently delivered from a composition containing a silicone elastomer, producing a higher sun protection factor (SPF). Silicone elastomer blends can be used to enhance SPF in oil-in-water compositions containing organic sunscreens. For example, in testing conducted regarding SPF, the addition of 4% silicone elastomer blend to a sun care composition containing organic sunscreens increased the SPF from 5.7 to 18. This property of the silicone elastomer allows the effectiveness of sunscreen agents in a composition to be maximized while reducing the amount needed to achieve a desired SPF. As a result, composition costs can be reduced along with potential irritation caused by sunscreen actives. Accordingly, a higher SPF can be achieved with the same amount of UV absorber, resulting in enhanced performance with no added composition cost. Silicone elastomers can be produced from linear silicone polymers by a variety of crosslinking reactions, e.g., by a hydrosilylation reaction in which a vinyl group reacts with a silicon hydride. The general process involves linear silicone polymers with reactive sites along the polymer chain reacting with a cross-linker. The dimethicone crosspolymer can be produced either as a gel made of a suspension of elastomer particles swollen in a carrier fluid (e.g., a mixture of high molecular weight silicone elastomer in cyclopentasiloxane such as Dow Corning® 9040 Silicone Elastomer Blend), or as a spray-dried powder (a dimethicone/vinyl dimethicone crosspolymer such as Dow Corning® 9506 Elastomer Powder). The gel form having desirable attributes is cyclomethicone, but low viscosity dimethicones and organic fluids can also be used. Examples of dimethicone crosspolymers in the suspension or gel form are high molecular weight silicone elastomer (12%) in decamethylcyclopentasiloxane (e.g., Dow Corning® ST-Elastomer 10) and a mixture of high molecular weight silicone elastomer in cyclopentasiloxane (e.g., Dow Corning® 9040 Silicone Elastomer Blend), which typically have an elastomer content ranging from 10 to 20% by weight.

In some embodiments, pentylene glycol is provided in a range of about 0.010% to about 10%, about 0.025% to about 5%, or about 0.05% to about 1.25% by weight. Suitable solvents for hydrophobic compositions include mineral oils, vegetable oils, and silicone oils. If desired, the peptide compositions as described herein may be dissolved or dispersed in a hydrophobic oil phase, and the oil phase may then be emulsified in an aqueous phase comprising water, alone or in combination with lower alcohols, glycerin, and/or glycols. In some embodiments, an anhydrous composition is applied as the presence of water can result in stinging upon administration to skin tissues subject to laser treatment, chemical peel, dermabrasion, or the like. Anhydrous compositions may also act to prevent the development of water-based irritant contact dermatitis in damaged or sensitive skin, which may produce rashes and skin irritation that may retard wound healing and improvement in skin quality. Tsai, T. F., Maibach, H. I. How irritant is water? An overview. Contact Dermatitis 41(6) (1999): 311-314 (describing contact dermatitis caused by water as an irritant). However, in certain embodiments it may be acceptable to provide water based compositions, or to permit a limited amount of water to be present. For example, water may be present, but at amounts below the threshold at which a stinging sensation when applied to damaged skin may result. Osmotic shock or osmotic stress is a sudden change in the solute concentration around a cell, causing a rapid change in the movement of water across its cell membrane. Under conditions of high concentrations of either salts, substrates or any solute in the supernatant, water is drawn out of the cells through osmosis. This also inhibits the transport of substrates and cofactors into the cell thus “shocking” the cell. Alternatively, at low concentrations of solutes, water enters the cell in large amounts, causing it to swell and either burst or undergo apoptosis. Certain of the compositions as described herein can be advantageously employed where it is desirable to minimize osmotic shock.
Compositions as described herein may comprise varying amounts of solvent. In some embodiments, the solvent is water. In some embodiments, the solvent is at least or about 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, or more than 95% by weight (wt. %). In some embodiments, the solvent is in a range of about 10% to about 95%, about 20% to about 90%, about 30% to about 85%, about 40% to about 80%, or about 50% to about 75% by weight.

Methylcellulose is preferred because it is readily and economically available and is easy to work with. Other suitable thickening agents include, for example, xanthan gum, carboxymethyl cellulose, hydroxypropyl cellulose, carbomer, and the like. The preferred concentration of the thickener will depend upon the thickening agent selected. An amount is preferably used that will achieve the selected viscosity. Viscous compositions are normally prepared from solutions by the addition of such thickening agents, or by employing a base that has an acceptable level of viscosity.

Methods and compositions as described herein may improve bruising following a cosmetic procedure. In some embodiments, methods and compositions improve bruising prior to a cosmetic procedure. In some instances, bruising is caused by red blood cells. Generally, red blood cells efficiently bind oxygen from the atmosphere, deliver it to the tissues, and help remove carbon dioxide. In some instances, red blood cells are involved in pathophysiologic problems with hemorrhage and extravasation of these cells into the tissue. Once outside the vascular system, red blood cells can quickly burst releasing free hemoglobin (Hb). That Hb may be prone to spontaneous oxidation and may be converted to higher oxidation states such as ferrylHb which have potent pro-inflammatory and pro-oxidant effects. See Jeney V, Eaton J W, Balla G, Balla J. Natural history of the bruise: formation, elimination, and biological effects of oxidized hemoglobin. Oxidative medicine and cellular longevity. 2013; 2013:703571. The heme that is released may be phagocytosed by macrophages. Following internalization by the macrophage, heme is cleaved into biliverdin, carbon monoxide, and iron. This mechanism can provide effective elimination of Hb, but it also assures iron recycling for new erythropoiesis (new red blood cell formation) under normal circumstances. See Jeney V, Eaton J W, Balla G, Balla J. Natural history of the bruise: formation, elimination, and biological effects of oxidized hemoglobin. Oxidative medicine and cellular longevity. 2013; 2013:703571. In some instances, leaving the byproducts of bleeding around for too long runs the risk of the pro-inflammatory effects. In some instances, these effects interfere with wound healing, promote pigmentation, or are unsightly. In some instances, delayed bruising results. See Sadeghpour M, Dover J S. Understanding Delayed Bruising After Hyaluronic Acid Injections: Why the Molecule and Not Just the Injection Matters—letters and communications. Dermatol Surg. 2019; 45(3):471-473. Compositions and methods as described herein, in some embodiments, improve bruising by removing by-products of red blood cell extravasation more efficiently. In some embodiments, compositions described herein result in improving function of macrophages.
Compositions as described herein comprising lactoferrin, phosphatidylserine, tripeptide-1, hexapeptide-12, hexapeptide-11, Arnica montana extract, Ledum palustre, or combinations thereof, in some embodiments, improve bruising. Lactoferrin is a plasmin inhibitor with high iron binding capacity and can aid in clearing lysed red blood cells and their constituents. Lactoferrin can block plasminogen activation on the cell surface by direct binding to human plasminogen, decreasing conversion to plasmin. Lactoferrin also has anti-microbial activity. See Zwirzitz A, Reiter M, Skrabana R, et al. Lactoferrin is a natural inhibitor of plasminogen activation. Journal of Biological Chemistry. 2018; 293(22):8600-8613.

Compositions and methods as described herein may result in elastin and/or collagen stimulation. Elastin is an assembly of microfibrils and tropoelastin (or soluble elastin). Elastin fibers are formed first by the synthesis of fibrillin microfibers which intertwine and then associate with tropoelastin (TE) protein molecules. TE molecules are bound together and cross linked together with fibrillin fibers by lysyl oxidase like enzyme 1 (LOXL1). The generated complex is then presented to the fibroblast by Fibulin 5 (FBLN5) which connects the complex to integrins that connect to the fibroblast. See Ashcroft, G. et al. Age-related Changes in the Temporal and Spatial Distributions of Fibrillin and Elastin mRNAs and Protein in Acute Cutaneous Wounds of Healthy Humans, Journal of Pathology. 1997; 183:80-89; Cenizo V, Andre{acute over ( )} V, Reymermier C, Sommer P, Damour O, E.

In some embodiments, elastin and/or collagen stimulation is a result of the compositions as described herein. In some embodiments, palmitoyl tripeptide-1 and palmitoyl hexapeptide-12 clear the extracellular matrix of aggregated fragmented collagen and elastin and then stimulate increased new collagen and elastin production. See Widgerow A D, Fabi S G, Palestine R F, et al. Extracellular Matrix Modulation: Optimizing Skin Care and Rejuvenation Procedures. journal of drugs in dermatology. 2016; 15(4s):S63-S71; Widgerow A. TOPICAL SKIN RESTORATION TECHNOLOGY—ADVANCES IN AGE MANAGEMENT STRATEGIES. MODERN AESTHETICS. 2016(May/June):1-8. In some embodiments, acetyl tetrapeptide-2 increases FBLN5 and LOXL1 protein levels, resulting in an increase in elastin synthesis. In some instances, acetyl tetrapeptide-2 upregulates genes related to Collagen 1 synthesis. Acetyl tetrapetide-2 can reduce parameters linked to skin flaccidity and dermal disorganization in vivo. See Product monograph: Uplevity™. Lipotec. June 2013.
In some embodiments, Anethum graveolens (dill extract) improves elastin and/or collagen stimulation by producing a reinduction of LOXL synthesis. See Cenizo V, Andre{acute over ( )} V, Reymermier C, Sommer P, Damour O, E. P. LOXL as a target to increase the elastin content in adult skin: a dill extract induces the LOXL gene expression. Experimental dermatology. 2006; 15:574-581. While microfibrils and soluble elastin continue to be synthesized throughout life, LOXL dramatically decreases from the age of 18. Increased levels of LOXL in the skin cause the assembly of microfibrils and tropoelastin, leading to improved mechanical properties of the skin. Id. Elastogenesis mainly occurs until the end of the second decade of the life, although the global content of skin elastin can increase after that, the nature of this elastin protein is often suboptimal and dysfunctional. See Ashcroft, G. et al. Age-related Changes in the Temporal and Spatial Distributions of Fibrillin and Elastin mRNAs and Protein in Acute Cutaneous Wounds of Healthy Humans, Journal of Pathology. 1997; 183:80-89. After this period, the elastin gene and fibrillin-1 gene are still active throughout the life although elastogenesis becomes low or inefficient. See Cenizo V, Andre{acute over ( )} V, Reymermier C, Sommer P, Damour O, E. P. LOXL as a target to increase the elastin content in adult skin: a dill extract induces the LOXL gene expression. Experimental dermatology. 2006; 15:574-581. LOXL, which declines after the first decades of life, has been shown to stimulate elastogenesis and maintain elastic fibers homeostasis. Id.; Noblesse E, Cenizo V, Bouez C, et al. Lysyl oxidase-like and lysyl oxidase are present in the dermis and epidermis of a skin equivalent and in human skin and are associated to elastic fibers.

In some instances, dill extract increases the expression of LOXL in fibroblasts and in the skin engineering models and to de novo elastogenesis in vivo. See Cenizo V, Andre{acute over ( )} V, Reymermier C, Sommer P, Damour O, E. P. LOXL as a target to increase the elastin content in adult skin: a dill extract induces the LOXL gene expression.

See Product monograph: Symdecanox, Symrise June 2015.
In some embodiments, Tremella fuciformis extract stimulates intrinsic hyaluronic acid production. In some embodiments, Tremella fuciformis provides high levels of moisture and anti-oxidant properties. See Li H, Lee H S, Kim S H, Moon B, Lee C. Antioxidant and anti-inflammatory activities of methanol extracts of Tremella fuciformis and its major phenolic acids. J Food Sci. 2014; 79(4):C460-468; Liao W C, Hsueh C Y, Chan C F. Antioxidative activity, moisture retention, film formation, and viscosity stability of Auricularia fuscosuccinea, white strain water extract. Biosci Biotechnol Biochem. 2014; 78(6):1029-1036.
In some embodiments, sodium hyaluronate crosspolymer stimulates intrinsic hyaluronic acid production.

Described herein are compositions and methods for stimulating adipogenesis. In some embodiments, fillers stimulate new adipose formation by mechanical stimulation of adipose stem cells in the dermal white adipose tissue layer. See Kruglikov I L, Wollina U. Soft tissue fillers as non-specific modulators of adipogenesis: change of the paradigm? Experimental dermatology. 2015; 24(12):912-915. In some embodiments, compositions comprising acetyl hexapeptide-38 stimulate adipogenesis. Hexapeptide-38 is a PGC1a stimulator (peroxisome proliferator-activated receptor-gamma—PPARγ—coactivator 1 alpha). PGC1a plays a central role in adipogenic activity. See Liang H, Ward W F. PGC-1alpha: a key regulator of energy metabolism. Adv Physiol Educ. 2006; 30(4):145-151. Compositions and methods as described herein may comprise a phospholipid delivery system to facilitate penetration and absorption of the materials through the stratum corneum. PGC1a strongly induces in differentiation of preadipocytes into white adipocytes under the influence of PPARγ. The young adipocytes formed under these conditions appear to be small and active, and this size and activity have been seen to be synergistic and in line with good elastin formation. See Ezure T, Amano S. Increment of subcutaneous adipose tissue is associated with decrease of elastic fibres in the dermal layer. Exp Dermatol. 2015; 24(12):924-929. As such, large, mature adipocytes have been associated with diminished elastin-manifesting as aged sagging skin—whereas younger, smaller, newly synthesized adipocytes are accompanied by increased elastin levels.
In some embodiments, the compositions as described herein stimulate adipogenesis by at least or about 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, or more than 95%. In some embodiments, the compositions as described herein stimulate adipogenesis by at least or about 0.5×, 1.0×, 1.5×, 2.0×, 2.5×, 3.0×, 3.5×, 4.0×, 5.0×, 6.0×, 7.0×, 8.0×, 9.0×, 10×, or more than 10×.

Stability testing of the compositions can be conducted as follows.
High temperature testing is now commonly used as a predictor of long-term stability. High temperature testing can be conducted at 37° C. (98° F.) and 45° C. (113° F.). If a product is stored at 45° C. for three months (and exhibits acceptable stability) then it should be stable at room temperature for two years. A good control temperature is 4° C. (39° F.) where most products will exhibit excellent stability. Sometime, the product is also be subjected to −10° C. (14° F.) for three months.
In some instances, stability of the product is assessed by passing three cycles of temperature testing from −10° C. (14° F.) to 25° C. (77° F.). In such cases, the product is placed at −10° C. for 24 hours and then placed at room temperature (25° C.) for 24 hours. This completes one cycle. An even more rigorous test is a −10° C. to 45° C. five-cycle test. This puts emulsions under a tremendous stress.
The dispersed phase (of an oil-in-water emulsion) has a tendency to separate and rise to the top of the emulsion forming a layer of oil droplets. This phenomenon is called creaming. Creaming is one of the first signs of impending emulsion instability. A test method to predict creaming is centrifugation. Heat the emulsion to 50° C. (122° F.) and centrifuge it for thirty minutes at 3000 rpm. Then inspect the resultant product for signs of creaming.
Both formulas and packaging can be sensitive to the UV radiation. The product is placed in glass and the actual package in a light box that has a broad-spectrum output. Another glass jar completely covered with aluminum foil serves as a control. Discoloration of the product may be observed.
For all the above mentioned tests the color, odor/fragrance, viscosity, pH value, and, if available, particle size uniformity and/or particle agglomeration under the microscope can be observed.

On the day of the assay, the media was replaced with the various peptide or compound treatments. RBCs were then added to macrophages at a 100:1 RBC to macrophage ratio. The cells were then incubated at 37° C. and 5% CO2. After 24 hours the non-phagocytosed RBCs were washed away, macrophages lysed, and heme assay substrate added to detect absorbed RBCs/heme 15 minutes later. Concentrations of the peptides included the following: 2.9 ug/mL of tripeptide-1, 100 ug/mL of hexapeptide-11, and 2.9 ug/mL of hexapeptide-12. Comparisons of lactoferrin and phosphatidylserine were relative to no treatment (NT) PBS control. Each 0.1 increment on the y-axis demonstrates a 10% increase in efficacy of macrophage function representing significant increase in RBC phagocytosis.
Effects of various peptide treatments on phagocytosis were then determined.
The effect of phosphatidylserine was also determined.
The effects of lactoferrin were determined.
The effects of hydroxysuccinimide were determined.
The effects of tripeptide-1, hexapeptide-11, hexapeptide-12, phosphatidylserine, and lactoferrin on phagocytosis were determined.
The effects of the composition of Table 1 are evaluated in subjects following injection of a dermal filler. Twenty subjects are chosen to participate in the trial. Exclusion and inclusion criteria are listed in Table 2.
Each subject will receive two BOTOX® Cosmetic injections: one on a first side of an affected facial region and a second on a second side of the affected facial region. After two weeks, the subjects will apply the composition of Table 1 twice daily. Assessments are taken at 3, 4, 6, 8, and 12 weeks. Improvements in the subjects are determined using Physician Global Aesthetic Improvement Scale (PGAIS).
The objective of this study is to evaluate the efficacy and safety of a topical product comprising a formula as described Table 1 in dissipating a bruise compared to a bland moisturizer.
The duration of the study is 3 months. Approximately 10 subjects will be enrolled per site with up to 3 sites that are participating. Subjects include healthy male and female subjects 18 years of age or older. The inclusion criteria and exclusion criteria are listed in Table 3.
The study will consist of a screening visit, one laser induced procedure visit and follow-up visits on post bruise Days 2, 4, 6, 8, 10 and 14. Subjects that have opted for the biopsies will return at a designated time-point after the initial biopsies for a second set of biopsies. Subjects may consent for the study up to 30 days before Visit 1.
Visit 1 procedures will consist of the following: Completion of ICF, demographics, medical/dermatological history and study criteria confirmation. If the subject is eligible for the study, the subject will undergo a laser procedure on the right and left inner arm in order to induce a bruise. Standard photography will be taken pre and post bruise formation on each arm. Subjects will be randomized to receive either topical bruise product or bland moisturizer on the right or left arm. Subjects will use the topical product twice daily on the designated arm. Subjects receiving a forearm biopsy will put the randomized designated product on the forearm twice daily.
On follow-up Days 2, 4, 6, 8, 10 and 14, the subject will return to the clinic and be queried for any changes in health status since the previous visit. Subject and Investigator assessments will be completed. Standardized photography will be completed.
At week 2, two subjects that have opted for forearm biopsies will return to the office for the second biopsies and then return for stitch removal as per first biopsy.
Study measurements for efficacy include standardized photography, biopsies, and subject satisfaction questionnaire. Standardized photos will be taken at every visit and pre-post procedure. These photos will be used for comparable assessment of the bruises. Biopsies will be taken of two arbitrarily patients that consent to a biopsy of the forearms at Visit 1 and at two weeks post use of the topical products. The specimens will be reviewed by a blinded dermatopathologist. Subject will rate satisfaction with the product and delivery using the subject satisfaction questionnaire. Further safety will be determined by recording the number of adverse events (AE) per schedule of events.
Measurements for efficacy include co-primary efficacy endpoints, which comprise Global Improvement in the bruises between arms. Secondary efficacy endpoints will also be measured. The secondary efficacy endpoints include changes from Baseline in dermatopathology, dermal changes from skin biopsy, and Subject Satisfaction Questionnaire at end of study. Safety endpoints will also be measured including incidence (severity and causality) of any local and systemic adverse events (AEs).

A liposomal preparation was prepared according to the schematic as seen in
Efficacy of liposomal compositions was tested for bioavailability and skin penetration.
A water suspension of liposomes was prepared with 1.5% of hydrophilic molecule A or 300 ppm (0.03%) hydrophilic molecule B, and 27% Pro-Lipo™ Neo. Molecule A was caffeine and had a molecular weight of 194.2 g/mol and a penetration ability of log Kow of −0.07. Molecule B was a hexapeptide (hexapeptide-38) with a molecular weight of (870 g/mol) and a penetration ability log Kow of −1.13. A water solution with 1.5% A or 300 ppm B was used as a control (non-entrapped molecule).
A dose of 10 mg/cm2 was applied on skin explants using the Franz cell method. The kinetic of the molecules passed through skin explants was measured during 24 hours. After 24 hours, the molecule content was measured in each skin compartment including the stratum corneum, epidermis, dermis, and receptor fluid.
The particle size of liposomal acetyl hexapeptide 38 was determined.
100 uL of liposomal acetyl hexapeptide 38 was dissolved in 15 mL of water. Assay information can be seen in Table 5 for two experiments.
Results from the experiments can be seen in Tables 6-8 and
As seen in Tables 6-8 and
Exemplary liposomal formulation is seen in Table 9.
Study Design
A 2-center, randomized, double-blind study was undertaken to assess the efficacy and safety of a topical product formulated to increase the elimination of blood products that manifest as a bruise. This study investigated the ability of the topical product comprising a formula as described in Table 9 to improve the appearance of a bruise compared to a bland moisturizer. 18 subjects were recruited the study and 16 subjects (32 bruises) completed the study.
Eligible subjects received an induced bruise on both arms via mechanical disruption, venipuncture, of a vessel as in a blood draw (1 group) or via removal of blood and re-injection of 0.1 mL subdermally in the proximal inner forearm just distal to the antecubital fossa.
Subjects were randomized to receive the topical product and bland moisturizer to use on the designated arm at a minimum of four times daily. One arm received the topical product on the bruise four times a day, and the other arm received the bland moisturizer (Cetaphil lotion) four times a day. Subjects were screened and underwent procedural (Day 0) visit and follow-up visits at days 1, 2, 3, 6, and 7. Two subjects consented to have a biopsy on the forearm at Day 0, pre-treatment, and at day 12/20 post procedure. Skin colorimetry (Skin ColorCatch) was performed in triplicate at each visit and clinical change of bruises documented through photography.
Assessed endpoints included global Improvement in the appearance of bruises between arms with comparison in Skin Color Catch measurements.
Results
18 subjects were recruited the study, and 16 subjects (32 bruises) completed the study as two subjects were withdrawn from analysis as they did not complete the study with sufficient data points. Objective assessment using colorimetry (SkinColorCatch, Delfin technologies, Kuopio, Finland) was performed. Measurement of the intensity of the blue/yellow channel was undertaken at all time points. This score was then compared with the baseline score prior to bruise creation and the delta between blue intensity and original clear skin was compared among the two groups and provided information of bruise resolution. In order to ensure equivalence of both groups, the scores immediately post bruising were determined to be comparable as demonstrated in
The 2 models showed slight variation. Subdermal injection manifested bruising slightly later; thus day 3 and 7 in this group was equivalent to day 2 and 6 in the blood draw group. The data demonstrated that the ‘tipping point’ occurred at day 2/3, where the color intensity of the experimental study product was significantly improved over the comparator. 81% of subjects applying the topical product had less bruising at Day 2/3 compared to the bland moisturizer, and there was a 72% improvement in purple intensity score, demonstrating that the topical product hastened resolution of bruising as seen in
As seen in
Swelling was also measured. Subjects underwent Profound Radiofrequency (RF) Microneedling procedure and were administered the topical product comprising a formula as described in Table 9 or a bland moisturizer. Split face case studies were used to compare the topical product and the bland moisturizer. A Quantificare 3-D volumetric camera was used for measurements. Red color indicates greater volume/swelling compared to baseline. Data is seen in
