Hyaluronic acid (HA) is an anionic, nonsulfated glycosaminoglycan distributed widely throughout connective, epithelial, and neural tissues. It is unique among glycosaminoglycans in that it is nonsulfated, forms in the plasma membrane instead of the Golgi apparatus, and can be very large, with its molecular weight often reaching the millions. One of the chief components of the extracellular matrix, hyaluronan contributes significantly to cell proliferation and migration, and may also be involved in the progression of some malignant tumors.
HA is also a major component of skin. Skin provides a mechanical barrier to the external environment, and acts to prevent the ingress of infectious agents. Once injured, however, the tissues beneath the skin are exposed to infection; therefore, rapid and effective healing is of crucial significance to reconstruct the barrier function. Skin wound healing is a complex process, and includes many interacting processes initiated by haemostasis and the release of platelet-derived factors. The following stages are inflammation, granulation tissue formation, reepithelization and remodeling. HA is likely to play a multifaceted role in mediation of these cellular and matrix events.
There exists a need for compositions, and methods of topical administration thereof, that increase the concentration of glycosaminoglycans (GAG), such as HA, in skin, thereby increasing the ability of skin to repair itself.
In certain embodiments, the invention relates to a method of increasing the gluyosaminoglycan concentration in an area of skin of a subject, comprising the steps of:
applying to the area of skin a therapeutically-effective amount of a first formulation;
applying to the area of skin a therapeutically-effective amount of a second formulation; and
applying to the area of skin a therapeutically-effective amount of a third formulation.
In certain embodiments, the invention relates to a method of increasing the glycosaminoglycan concentration in an area of skin of a subject, comprising the steps of:
applying to the area of skin a therapeutically-effective amount of a second formulation.
In certain embodiments, the invention relates to any one of the aforementioned methods, wherein the second formulation comprises
water, in a quantity from about 25% to about 75% by weight;
a plurality of moisturizers, emollients, humectants, or skin soothing agents in a quantity from about 18% to about 54% by weight;
a plurality of plant extracts or fruit seed extracts in a quantity from about 1% to about 3% by weight; and
a plurality of peptides or peptide complexes in a quantity from about 0.06% to about 0.18% by weight.
Overview
In certain embodiments, the invention relates to formulations that, once applied to the skin, increase dermal GAG concentrations.
In certain embodiments, the invention relates to a multi-step skin treatment regimen that increases the rate of production of GAG in the skin or increases the retention of GAG by the skin, as compared to a single-step skin treatment regimen. In certain embodiments, the multi-step regimen shows superior results in about 45 days or about 90 days.
In certain embodiments, the three-step regimen involves a first formulation. In certain embodiments, the first formulation is in the form of a dermal peel. In certain embodiments, the first formulation is applied for a first number of days per month. In certain embodiments, the first formulation is applied for a first number of consecutive days per month. In certain embodiments, the first formulation is applied once per day for a first number of days per month. In certain embodiments, the first formulation prepares the skin for treatment with a second formulation. In certain embodiments, the first formulation improves the bioavailability of the second formulation.
In certain embodiments, the three-step regimen involves a second formulation. In certain embodiments, the second formulation is in the form of a foam, a cream, or a lotion. In certain embodiments, the second formulation is applied for a second number of days per month. In certain embodiments, the second formulation is applied for a second number of consecutive days per month. In certain embodiments, the second formulation is applied once per day for a second number of days per month. In certain embodiments, the second formulation is applied twice per day for a second number of days per month. In certain embodiments, the second formulation stimulates the production of GAG by the skin.
In certain embodiments, the three-step regimen involves a third formulation. In certain embodiments, the third formulation is in the form of a foam, a cream, or a lotion. In certain embodiments, the third formulation is applied for a third number of days per month. In certain embodiments, the third formulation is applied for a third number of consecutive days per month. In certain embodiments, the third formulation is applied once per day for a third number of days per month. In certain embodiments, the third formulation is applied twice per day for a third number of days per month. In certain embodiments, the third formulation substantially restores the skin's barrier function after treatment with the second formulation. In certain embodiments, the third formulation substantially reduces irritation of the skin after treatment with the second formulation.
Definitions
For convenience, certain terms employed in the specification and appended claims are collected here. These definitions should be read in light of the entire disclosure and understood as by a person of skill in the art.
The indefinite articles “a” and “an,” as used herein in the specification and in the claims, unless clearly indicated to the contrary, should be understood to mean “at least one.”
The phrase “and/or,” as used herein in the specification and in the claims, should be understood to mean “either or both” of the elements so conjoined, i.e., elements that are conjunctively present in some cases and disjunctively present in other cases. Multiple elements listed with “and/or” should be construed in the same fashion, i.e., “one or more” of the elements so conjoined. Other elements may optionally be present other than the elements specifically identified by the “and/or” clause, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, a reference to “A and/or B”, when used in conjunction with open-ended language such as “comprising” can refer, in one embodiment, to A only (optionally including elements other than B); in another embodiment, to B only (optionally including elements other than A); in yet another embodiment, to both A and B (optionally including other elements); etc.
The phrase “or,” as used herein in the specification and in the claims, should be understood to mean “either or both” of the elements so conjoined, i.e., elements that are conjunctively present in some cases and disjunctively present in other cases. Multiple elements listed with “or” should be construed in the same fashion, i.e., “one or more” of the elements so conjoined. Other elements may optionally be present other than the elements specifically identified by the “or” clause, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, a reference to “A or B”, when used in conjunction with open-ended language such as “comprising” can refer, in one embodiment, to A only (optionally including elements other than B); in another embodiment, to B only (optionally including elements other than A); in yet another embodiment, to both A and B (optionally including other elements); etc.
As used herein in the specification and in the claims, the phrase “at least one,” in reference to a list of one or more elements, should be understood to mean at least one element selected from any one or more of the elements in the list of elements, but not necessarily including at least one of each and every element specifically listed within the list of elements and not excluding any combinations of elements in the list of elements. This definition also allows that elements may optionally be present other than the elements specifically identified within the list of elements to which the phrase “at least one” refers, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, “at least one of A and B” (or, equivalently, “at least one of A or B,” or, equivalently “at least one of A and/or B”) can refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including elements other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including elements other than A); in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally including other elements); etc.

The concentration of the HFO propellant is about 2% to about 50% by weight of the composition. Hydrocarbon as well as CFC propellants can also be used in the present invention.
2. Vehicles
Suitable topical vehicles and vehicle components for use with the formulations of the invention are well known in the cosmetic and pharmaceutical arts, and include such vehicles (or vehicle components) as water; organic solvents such as alcohols (particularly lower alcohols readily capable of evaporating from the skin such as ethanol), glycols (such as propylene glycol, butylene glycol, and glycerol (glycerin)), aliphatic alcohols (such as lanolin); mixtures of water and organic solvents (such as water and alcohol), and mixtures of organic solvents such as alcohol and glycerol (optionally also with water); lipid-based materials such as fatty acids, acylglycerols (including oils, such as mineral oil, and fats of natural or synthetic origin), phosphoglycerides, sphingolipids and waxes; protein-based materials such as collagen and gelatin; silicone-based materials (both non-volatile and volatile) such as cyclomethicone, dimethiconol, dimethicone, and dimethicone copolyol; hydrocarbon-based materials such as petrolatum and squalane; and other vehicles and vehicle components that are suitable for administration to the skin, as well as mixtures of topical vehicle components as identified above or otherwise known to the art.
In one embodiment, the compositions of the present invention are oil-in-water emulsions. Liquids suitable for use in formulating compositions of the present invention include water, and water-miscible solvents such as glycols (e.g., ethylene glycol, butylene glycol, isoprene glycol, propylene glycol), glycerol, liquid polyols, dimethyl sulfoxide, and isopropyl alcohol. One or more aqueous vehicles may be present.
In one embodiment, formulations without methanol, ethanol, propanols, or butanols are desirable.
3. Surfactants and Emulsifiers
Many topical formulations contain chemical emulsions which use surface active ingredients (emulsifiers and surfactants) to disperse dissimilar chemicals in a particular solvent system. For example, most lipid-like (oily or fatty) or lipophilic ingredients do not uniformly disperse in aqueous solvents unless they are first combined with emulsifiers, which form microscopic aqueous soluble structures (droplets) that contain a lipophilic interior and a hydrophilic exterior, resulting in an oil-in-water emulsion. In order to be soluble in aqueous media, a molecule must be polar or charged so as to favorably interact with water molecules, which are also polar. Similarly, to dissolve an aqueous-soluble polar or charged ingredient in a largely lipid or oil-based solvent, an emulsifier is typically used which forms stable structures that contain the hydrophilic components in the interior of the structure while the exterior is lipophilic so that it can dissolve in the lipophilic solvent to form a water-in-oil emulsion. It is well known that such emulsions can be destabilized by the addition of salts or other charged ingredients which can interact with the polar or charged portions of the emulsifier within an emulsion droplet. Emulsion destabilization results in the aqueous and lipophilic ingredients separating into two layers, potentially destroying the commercial value of a topical product.
Surfactants suitable for use in the present invention may be ionic or non-ionic. These include, but are not limited to: sodium isostearate, cetyl alcohol, polysorbates (Polysorbate 20, Polysorbate 40, Polysorbate 60, Polysorbate 80), steareth-10 (Brij 76), sodium dodecyl sulfate (sodium lauryl sulfate), lauryl dimethyl amine oxide, cetyltrimethylammonium bromide (CTAB), polyethoxylated alcohols, polyoxyethylene sorbitan, octoxynol, N,N-dimethyldodecylamine-N-oxide, hexadecyltrimethylammonium bromide (HTAB), polyoxyl 10 lauryl ether, bile salts (such as sodium deoxycholate or sodium cholate), polyoxyl castor oil, nonylphenol ethoxylate, cyclodextrins, lecithin, dimethicone copolyol, lauramide DEA, cocamide DEA, cocamide MEA, oleyl betaine, cocamidopropyl betaine, cocamidopropyl phosphatidyl PG-dimonium chloride, dicetyl phosphate (dihexadecyl phosphate), ceteareth-10 phosphate, methylbenzethonium chloride, dicetyl phosphate, ceteth-10 phosphate (ceteth-10 is the polyethylene glycol ether of cetyl alcohol where n has an average value of 10; ceteth-10 phosphate is a mixture of phosphoric acid esters of ceteth-10), ceteth-20, Brij S10 (polyethylene glycol octadecyl ether, average Mn˜711), PEG-20 phytosterol, and Poloxamers (including, but not limited to, Poloxamer 188 (HO(C2H4O)a(CH(CH3)CH2O)b(C2H4O)aH, average molecular weight 8400) and Poloxamer 407 (HO(C2H4O)a(CH(CH3)CH2O)b(C2H4O)aH, wherein a is about 101 and b is about 56)).
