Description
Method of Treating Skin Pigmentation and Formulation for Treatment
BACKGROUND
Field of the Invention
[0001] The present invention relates generally to treatments for skin pigmentation along with products used to treat skin pigmentation. More specifically, the present invention relates to exosome-based methods and products for treating skin pigmentation disorders.
Description of the Related Art
[0002] For many individuals, the appearance of the skin is an important part of individual identity. A person’s skin changing in pigmentation from what is expected, or desired, can create a large amount of stress for the individual. The most common types of skin pigmentation changes are a result of melasma, hyperpigmentation, rosacea, or vitiligo.
[0003] Current treatments for skin pigmentation changes are facial acids, such as alpha hydroxy acids, azelaic acid, salicylic acid, and ascorbic acid, retinoids, chemical peels, laser peels, intense pulse light therapy, dermabrasion and microdermabrasion, and lightening creams. Other treatments for specific skin pigmentation changes include tranexamic acid and platelet-rich plasma injections (for melasma), oral antibiotics or acne drugs (for rosacea), and surgery (for stable vitiligo).
[0004] Many of these treatments have undesirable side effects that may even counteract the desired effects, including furthering the skin discoloration for some individuals. Acids applied incorrectly can bum the skin, resulting in more skin discoloration and severe discomfort in the burned areas; retinoids have been shown to increase sensitivity to UV light. Other treatments require expensive and time-consuming trips to a dermatologist’s office and are rarely singletreatment approaches.
[0005] It would be beneficial to have a single product that is useful in treating all of these reasons for skin discoloration that has limited side effects.
SUMMARY
[0006] In accordance with the embodiments herein, a method for treating skin discoloration, along with formulations for use, is described. The method comprises applying an exosome-based
skincare product to skin that has skin pigmentation issues. The exosome-based skincare product contains exosomes produced by and excreted from human umbilical mesenchymal stem cells cultured in vitro under specific conditions and then contained within a solvent. Note that the exosome-based skincare product does not contain live human umbilical mesenchymal stem cells. Optional ingredients such as skin-conditioning agents, antioxidants, surfactants, buffering agents, viscosity decreasing agents, viscosity increasing agents, peptides, binders, and/or humectants may be included.
DETAILED DESCRIPTION OF EMBODIMENTS
[0007] In the following description, for purposes of explanation and not limitation, details and descriptions are set forth in order to provide a thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced in other embodiments that depart from these details and descriptions without departing from the spirit and scope of the invention.
[0008] For the purpose of definition, within this document the term “media” is used to mean any substrate which can contain an exosome-based product and is not to be read as the plural form of “medium”. Appropriate substrates for skincare are well known within the industry and as such are not discussed in detail herein.
[0009] For the purpose of definition, within this document, the term “human umbilical mesenchymal stem cells” is used to mean any preparation of human umbilical mesenchymal stem cells, including human umbilical mesenchymal stem cells contained within human umbilical stem cell conditioned media. Within the industry, human umbilical mesenchymal stem cells are known by a number of different names, including but not limited to human Wharton’s Jelly derived mesenchymal stem cells, human Wharton’s Jelly derived mesenchymal stromal cells, human umbilical derived mesenchymal stromal cells, hUMSCs, hWJMSCs, Wharton's Jelly derived multipotent progenitor cells, and umbilical derived multipotent progenitor cells. Additionally, these stem cells can be identified by cell surface markers, such as CD90+, CD105+, CD73+, and CD45-.
[0010] Within this document, the exosomes discussed are much smaller than a typical mesenchymal stem cell, about 1/100th the size of a cell, and have a diameter of approximately 30- 150 nanometers (run). Exosomes are roughly spherical and made up of a lipid bilayer produced by
the cell they originated from. This lipid bilayer forms a protective ‘shell’ or outer casing, and within the ‘shell’ or outer casing is the exosome pay load which contains molecules deposited there by the cell that generated the exosome. While exosomes are generated using some of the origin cell’s own cellular material, the exosomes do not contain cells, nor are they explicitly cellular material.
[0011] In an illustrative embodiment of the invention, the method comprises the step of applying an exosome-based skincare product to skin that has skin pigmentation issues. The exosome-based skincare product contains exosomes in or derived from a media conditioned by human umbilical mesenchymal stem cells within a solvent. In optional embodiments, skinconditioning agents, antioxidants, surfactants, buffering agents, viscosity decreasing agents, viscosity increasing agents, peptides, binders, and/or humectants may be included. Other optional ingredients are contemplated and described herein. Frequently, all of these optional ingredients are included with the human umbilical mesenchymal stem cell derived exosomes, or media, and solvent. Additional optional ingredients beyond those explicitly described herein are contemplated.
[0012] In most embodiments, the solvent is water. However, oil-based solvents are contemplated.
[0013] Skin-conditioning agents within the skincare industry are vast and well documented. Any of the well-known skin-conditioning agents work well with the invention and is contemplated. Specifically, glycerin, sodium hyaluronate, niacinamide, panthenol, Caesalpinia spinosa gum, ceramide NP, ceramide AP, ceramide EOP, yeast extract, Citrullus ianatus fruit extract, Pyrus malus fruit extract, Lens esculenta fruit extract, sodium PCA, caprylyl glycol, ethylhexylglycerin, hydrolyzed sodium hyaluronate, and phytosphingosine are frequently used with the invention. [0014] As with skin-conditioning agents, antioxidants are well known and well documented. With the invention, the antioxidants most frequently used are ascorbic acid, magnesium ascorbyl phosphate, ascorbyl glucoside, sodium ascorbyl phosphate, tetrahexyldecyl ascorbate, glutathione, and Camellia sinensis leaf extract. Any other well-known antioxidants in the skincare industry can be and is contemplated.
[0015] Surfactants frequently used with the invention include polysorbate 20, polysorbate 60, and sodium lauroyl lactylate. Any other well-known surfactant in the skincare industry can be used and is contemplated. While not a surfactant itself, cholesterol is commonly used to stabilize the
emulsions that are achieved with surfactants. Some embodiments of the exosome-based skincare product include cholesterol.
[0016] Buffering agents, such as sodium lactate, disodium phosphate, and sodium phosphate most frequently used with the invention, are common in the skincare industry. As many skincare products have harsh pH, both acidic and basic, buffers are frequently used to ensure that the final product is of a neutral pH for the skin. Other well-known buffering agents in the skincare industry are acceptable and are contemplated.
[0017] Viscosity increasing and decreasing agents are frequently used in the skincare industry. Those most frequently used with the invention are hydroxyethylcellulose, Caesalpinia spinosa gum, dextran, carbomer, hexylene glycol, and butylene glycol.
