The present document describes an oral care composition comprising a cuttlefish bone powder, comprising particles having more than 95% (w/w) calcium carbonate content, and a particle size of from about 60 microns to about 75 microns, and a suitable carrier, and uses of said composition for oral hygiene.

Pro-toothpaste compositions formulated to receive a volume of allergen solution to provide toothpastes that exhibit efficacy for oral mucosal immunotherapy (OMIT) and acceptable consumer and product stability properties, along with kits of pro-toothpaste, allergen/extracts of allergens, and optionally compounding means and/or specialized toothbrushes are provided. Toothpastes suitable and effective for OMIT and methods for managing allergic symptoms and for reducing risk of allergy in people without symptoms employing the pro-toothpastes, toothpastes and kits of the invention are also disclosed.

A skin whitening program, comprising an external application step, a treatment step and an oral administration step. A skin care product for external application is selected from a whitening, brightening or yellow-removing skin care product, the effective ingredient in the skin care product being selected from a tricholoma matsutake, carthamus tinctorius or rhodiola rosea extract, a tricholoma matsutake, glycyrrhiza uralensis or pearl extract, or a panax notoginseng, salvia miltiorrhiza or radix astragali extract. A beautifying device for treatment is selected from an iontophoresis, microcurrent or LED green light beautifying device. A beautifying food for oral administration is selected from an antioxidant, blood and qi invigorating or anti-glycation food, the effective ingredient in the food being selected from a schisandra chinensis, panax quinquefolius or ophiopogon japonicus extract, a salvia miltiorrhiza, crataegus pinnatifida or ginkgo biloba extract, or an olive, osmanthus fragrans or scutellaria baicalensis extract.

The present disclosure discloses a skin penetration enhancing composition and a use thereof in preparation of a skin delivery formulation. The skin penetration enhancing composition comprises sponge spicules and nanoparticles. The nanoparticles comprise at least one of one or more drugs or one or more cosmetic active ingredients.

A composition for preventing the hair loss or promoting the hair growth includes Wnt protein-derived peptides and polydeoxyribonucleotides as an active ingredient, and increases the secretion of -catenin. By the cell activation and activation of signal transduction pathway for promoting the hair growth signaling system, the growth of hair constituent cells, such as keratinocytes, fibroblasts and dermal papilla cells, is increased to prevent the hair loss or promote the hair growth. Wnt protein-derived peptides and polydeoxyribonucleotides are used as a cosmetic composition, a pharmaceutical composition or a health food composition for preventing the hair loss or promoting the hair growth.

Stabilized skin care compositions are described. The compositions comprise a fish oil component that yields a product of oxidation and the component is stabilized with a radical scavenger, a peroxide decomposer and hydroxylated fatty acid and/or a derivative thereof.

A hair cosmetic that has a better color when performing hair dye includes a hair cosmetic composition containing an alkali agent, an amino acid, a higher alcohol having 12 to 22 carbon atoms, a surfactant, and a thickener. The alkaline agent may be at least one of aqueous ammonia, ammonium carbonate, sodium carbonate, ethanolamines, ammonium bicarbonate, and arginine.

Methods of protecting skin of a mammal by application of silk-derived compositions useful for treating or preventing a wide variety of skin conditions. Silk solutions and silk mats are prepared and applied to the skin surface. The silk compositions may be self-adhesive or sutured to cover a wound or area of skin exposed to physical stresses and strains, thereby preventing a wound and/or promoting wound healing.
