Skin is composed of three superposed layers that are, from surface to body depth, epidermis, dermis and hypodermis. The epidermis can be divided, according to morphological and histological criteria, into four layers, from the deepest to the outermost: the basal lamina and the spinosal layer (which form the deep epidermis), and the granular layer (superficial epidermis) and the corneal layer (or stratum corneum). The epidermis is in contact with the external environment. One of the roles of the epidermis is to protect the organism from dehydration, as well as chemical, mechanical and biological exterior aggressions.
The dermis is an irrigated connective tissue mostly composed of fibroblasts and of an extracellular matrix, which include macromolecules such as collagen, elastin and fibronectin fibers. It assumes a nourishing and support function with regard to the epidermis.
Skin is known to have a tendency to dry due to environmental, psychological and hormonal factors. It is important that skin be well moisturized to prevent dry skin, including symptoms of redness, itchiness, irritation, dry patches, peeling, cracking and/or swelling. Similarly, dehydrated skin results in tightening of the skin, and/or the loss of flexibility and elasticity. Skin may become rough, even scaly.
There is an ongoing desire for personal care compositions that can improve the health and appearance of skin, such as reduced wrinkles and/or skin tightening effects.
Aspects of the present invention relate to personal care compositions for improving the health of keratin and, particularly, for improving the health and appearance of skin. In accordance with an aspect of the invention, provided is a personal care composition containing a hyaluronic acid system, one or more peptides, and an extract comprising kangaroo paw flower extract. The hyaluronic acid system typically comprises a plurality of hyaluronic acids.
According to another aspect of the invention, provided is a personal care composition that comprises a hyaluronic acid system, one or more peptides, and a ferment. The ferment may comprise bacteria metabolized ferment, a fungi metabolized ferment, or a combination of two or more thereof. In some cases, the ferment is selected from a bacillus ferment, matsutake mycelium ferment, or a combination of two or more thereof.
In accordance with a further aspect of the invention, provided is a personal care composition including a hyaluronic acid system, one or more peptide, an extract, and sodium polyacryloyldimethyl taurate. The hyaluronic acid system of the personal care composition generally comprises a plurality of hyaluronic acids.
The personal care compositions disclosed herein may include a cross-linked hyaluronic acid that is an elastomer. Preferably, the hyaluronic acid system includes at least one low molecular weight hyaluronic acid, at least one medium molecular weight hyaluronic acid, and at least one high molecular weight hyaluronic acid.

An exemplary personal care composition (Ex. A) was prepared in accordance with aspects of the invention. The formulation for Ex. A is shown in Table 1 (below).
Two exemplary personal care compositions (Ex. B and Ex. C) were prepared in accordance with aspects of the invention. The formulations for Ex. B and Ex. C are shown in Table 2, below. A personal care composition (Control) was prepared without certain ingredients to serve as a control, as seen in Table 2.
Ex. B and Ex. C are evaluated to assess the effect of Ex. B and Ex. C in comparison to two commercial benchmark personal care compositions (Comparative Compositions 1 and 2). The list of ingredients for Comparative Composition 1 is provided below.
The list of ingredients for Comparative Composition 2 is provided below.
Specifically, samples of Ex. B and Ex. C as well as Comparative Compositions 1 and 2 were applied to in vitro skin samples and evaluated to determine the effect on extracellular matrix, cell turnover, hydration, skin barrier effectiveness, antioxidant, and inflammation. As further discussed below, various gene expressions were evaluated to determine the effect of the personal care compositions on the in vitro skin samples.
In vitro studies were conducted using MatTek's patented EpiDerm FT (Full Thickness) in vitro tissue system. Tissues were first normalized with tissue culture media by overnight incubation (incubated at 37° C. with 5% CO2). The tissues were then treated with the product (10 ul), applied, and the tissue samples incubated for 24 hours at 37° C. with 5% CO2. Post incubation the tissue samples were collected and processed to extract RNA.
RNA was extracted from EpiDerm FT (Full Thickness) using Polytron PT 10-35 GT (Kinematica, Bohemia, NY, USA) and the RNeasy Fibrous Tissue Mini Kit (Qiagen, Germantown, MD, USA) following the manufacturer's protocol. Extracted RNA was quantitated using NanoDrop One (ThermoFisher Scientific, Waltham, MA, USA), followed by cDNA synthesis using the Maxima First Strand cDNA Synthesis kit (ThermoFisher). In order to evaluate skin specific changes, 48 molecular targets (which included genes COL1A, COL3A, MMP1, HBEGF, Ki67, KRT14, CRABP2, ELOVL1, HAS2, GBAP1, SMPD1, OCCLUDIN, TJP-1, GSS, GPX1, SOD2, TXN, TXNRD1, IL-1alpha, CXCL-8/TL-8 TNF and CYP1A) were placed on Taqman™ array cards, and QuantStudio 7 Flex (ThermoFisher) was used for gene expression analysis. The results were expressed relative to the housekeeping gene and to the untreated or placebo control.
To assess the effect of each personal care composition on the extracellular matrix of the skin sample, the expression of Elastin, COL1A, COL3A and MMP1 were evaluated. MMP-1 breaks down the interstitial collagen types I, II, and III. Thus, a decrease in MMP-1 expression is beneficial to the skin of a user of the personal care composition. The level of Elastin expression, COL1A expression, COL3A expression, and MMP-1 expression for each of the personal care compositions is shown in
To assess the effect of each personal care composition on the cell turnover of the skin sample, the level of gene expression for HBEGF, Ki67, KRT14 and CRABP2 was determined. Heparin-binding EGF is a growth factor in the EGF family of proteins. Ki67 is a marker used to assess cellular proliferation. Keratin 14 is expressed in mitotically active cells in the basal layer of skin. CRABP2 transports retinoic acid to the nucleus, thereby promoting healthy regulation of cellular proliferation. The level of HBEGF expression, Ki67 expression, KRT14 expression, and CRABP2 expression for each of the personal care compositions is shown in
To assess the effect on hydration of the skin sample by the personal care compositions, the level of HAS2 expression was evaluated. HAS2 is an enzyme involved in hyaluronic acid synthesis. The level of HAS2 expression for each of the personal care compositions is shown in
To assess the effect of each personal care composition on the skin barrier effectiveness of the skin sample, the level of expression for ELOVL-1, GBAP1, SMPD1, Occludin and TJP-1 was evaluated. ELOVL-1 is an enzyme that regulates skin fatty acid biosynthesis. GBAP1 encodes for the enzyme that catalyzes skin barrier lipid ceramide formation. SMPD1 catalyzes the hydrolysis of sphingomyelin to ceramide. Occludin and TJP-1 are tight junction associated proteins that are involved in the barrier function of skin. The level of ELOVL-1 expression, GBAP1 expression, SMPD1 expression, Occludin expression, and TJP-1 expression for each of the personal care compositions are shown in
To assess the antioxidant effect of each personal care composition, the level of expression of GSS, GPX1, SOD2, TXN and TXNRD1 was determined. SOD2 destroys superoxide radicals that are normally produced within the cell. GSH protects cells by neutralizing and/or reducing reactive oxygen species. Glutathion peroxidase (GPX) is a cytosolic enzyme that catalyzes the reduction of hydrogen peroxide to water and oxygen. Thioredoxins are proteins that act as antioxidants by reducing other proteins by cysteine thiol-disulfide exchange. Thioredoxin reductase 1 reduces thioredoxins as well as other substrates and helps protect against oxidative stress. The level of GSS expression, GPX1 expression, SOD2 expression, TXN expression, and TXNRD1 expression for each of the personal care compositions is shown in
To assess the amount of inflammation stress due to the personal care compositions, the level of expression for IL-1α, CXCL-8 (IL-8), and TNF CYUP1A was evaluated. Cytokin interleukin-1α (IL-1α) is a mediator of an inflammatory response. Interleukin-8 attracts and activates neutrophils in inflammatory regions. The level of IL-1α expression, CXCL-8 (IL-8) expression, and TNF CYUP1A expression for each of the personal care compositions is shown in
An exemplary personal care composition (Ex. D) was prepared in accordance with aspects of the invention. The formulation of Ex. D is provided in Table 3.
Ex. D was assessed using a monadic evaluation to determine the anti-ageing efficacy of such personal care composition. Specifically, 50 female volunteers having ages ranging from 35 to 65 years and of all Fitzpatrick skin types with mild to moderate facial photoaging concerns (e.g., fine lines, wrinkles, sagging skin, tone and texture) were assessed during the monadic evaluation. The evaluation included volunteers having oily, dry normal, and combination skin types.
Volunteers who used any topical prescription or OTC facial products for 2 weeks prior to study entry or received any facial treatments in the past 6 months or were not willing to withhold all facial treatments during the course of the study including facial peels, dermabrasion, botulinum toxin, injectable fillers, energy-based treatments, or facial plastic surgery were excluded. Volunteers who used any OTC or prescription retinoid facial products within the past 3 months were also excluded.
Volunteers were asked to continue their self-selected cleanser and brand moisturizer for the prior 30 days for the 24-week duration of the study. A commercial sunscreen was provided for sun protection. Volunteers were asked to cleanse their face with a commercial wipe prior to any evaluations. Ex. D was applied twice daily to a clean, washed face and neck, and applications were recorded in a compliance diary.
A dermatologist evaluator completed baseline efficacy assessment (fine lines, wrinkles, skin evenness, radiance, plumping, texture/smoothness, sagging/firming/lifting, and global appearance) and tolerability assessment (erythema, irritation, and/or edema). The volunteers completed a baseline tolerability assessment (itching, stinging, and/or burning). Noninvasive assessments of corneometry to evaluate skin hydration were taken from a target site on the left cheek with a pin probe (e.g., the commercially available pin probes from DermaLab, Cortex Technologies, Hadsund, Denmark). The corneometer measures moisture content in the stratum corneum by an electrical capacitance method. The measurement has no units, but is proportional to the dielectric constant of the surface layers of the skin, and increases as the skin becomes more hydrated. Elasticity measurements were taken from a target site on the right cheek. The instrument applied a vacuum to the skin and measured the skin's elastic response. The probe was secured to the skin with double-sided tape. Negative vacuum pressure of 450 mbar was applied for 5 seconds and released for 10 seconds. The movement of the skin in and out of the probe was recorded during the application and release of the vacuum suction. The amount of extensibility, resiliency, and pure elasticity were recorded as VE (MPa), E (MPa) and Retraction Time (ms).
The dermatologist evaluator selected 20 volunteers for photography of the front, right, and left face with standard, cross-polarized, and parallel-polarized lighting. The volunteers were provided with a diary for compliance and the study product. The volunteers applied the study product to the entire face after facial cleansing every morning and evening. The provided sunscreen was used after application of Ex. D every morning. The volunteers recorded their applications in a compliance diary.
The dermatologist evaluator identified no tolerability issues in terms of erythema, irritation, or edema. Similarly, the volunteers did not identify any sensory issues of stinging, itching, or burning. The volunteers also assessed no odor or product stickiness issues.
Corneometry measurements were obtained from the left cheek at each visit to assess skin hydration. There was a statistically significant increase in skin moisturization immediately after product application of 54% (p<0.001) that continued for the entire 24 weeks of the study. At the study conclusion, there was a 35% increase in skin moisturization (p<0.001).
Elasticity measurements were taken with a negative pressure suction device on the right cheek. The elasticity was evaluated in terms of retraction time (RT), Young's Modulus (EM), and the calculated viscoelasticity. Retraction time is measured in milliseconds and represents a measurement of how long it takes for the skin to snap back to original conformation once it has been distended by the negative pressure vacuum pump. A decrease in retraction time means the skin is firmer. The retraction time decreased a statistically significant 16% at week 8 (p<0.001). This statistically significant improvement continued for the remainder of the evaluation increasing to 19% at week 24 (p<0.001). In other words, the skin was determined to be 19% firmer at the end of the 24-week evaluation when receiving Ex. D.
Viscoelasticity combines both the elevation and the retraction phase and is measured in megapascals. An improvement in viscoelasticity means the skin demonstrated less sagging or more lifting. The viscoelasticity demonstrated a statistically significant (p<0.001) improvement of 22% at week 8, which persisted at 21% at week 24. Thus, the skin demonstrated 21% less sagging or 21% more lifting after the 24-week evaluation of Ex. D (
The dermatologist evaluator assessed fine lines, wrinkles, skin evenness, radiance, plumping, texture/smoothness, sagging/firming/lifting, and global appearance. All assessments were made on a 5-point ordinal scale (0=none, 1=minimal, 2=mild, 3=moderate, 4=severe). There was immediate statistically significant improvement in radiance (p<0.001) and texture (p=0.003). This improvement continued into week 1. By week 2, there was statistically significant improvement in radiance (p<0.001), texture (p<0.001), and evenness (p=0.008), but also overall appearance (p<0.001). Cumulative improvement continued into weeks 12, 16, 20, and 24 when all evaluated criteria were statistically significant (p<0.001). By week 24, there was a 40% improvement in lines, a 23% improvement in wrinkles, a 42% improvement in evenness, a 64% improvement in radiance, a 58% improvement in plumping, a 65% improvement in texture, a 60% improvement in firmness, and a 45% improvement in overall appearance (
An exemplary personal care composition (Ex. E) was prepared in accordance with aspects of the invention. The formulation of Ex. E is provided in Table 4.
Ex. E and Comparative Composition 1 were evaluated using skin explants to assess the effect of such personal care compositions on skin. The skin explants (NativeSkin Access 11 mm) were obtained from a 53 year old female donor.
A 10 uL sample of Control Composition 1 or Ex. E was applied to the tissue surface of skin explants every other day over a period of 3 days and 7 days, respectively. Untreated skin explant samples were prepared by not applying either Ex. E or Comparative Composition 1.
After eight days of applying either Ex. E or Comparative Composition 1, the skin explants samples were processed. Specifically, the skin explant samples were placed in a RNAlater solution for RNA extraction, or fixed in 4% paraformaldehyde for immunostaining. To immunofluorescent stain the skin explant samples, the fixed skin explant samples were embedded in paraffin and sectioned at 5 μm. Three biomarkers were evaluated by immunofluorescence staining, namely anti-elastin and Collagen 1 antibodies.
To visualize the nuclei with DAPI (available from Vector Laboratories, Burlingame, CA, USA), 3 images per treatment per section/replicate were taken. The mean gray intensity of the images (for Collagen 1 and Loricrin) per amount of protein expressed and length of elastin fibers (in μm, three fiber lengths per image) was evaluated. All images were obtained using Leica EVOS FL Auto (Life technologies) and analyzed by using ImageJ (Version 1.53s, NIH, Bethesda, MD, USA).
