摘要:This invention provides compositions and methods of manufacturing such compositions that employ GRAS compounds which can act to promote the generation of stem, epidermal or other skin cells in the epidermis, activation of collagen synthesis, activation of hyaluronic acid synthesis, enhanced skin hydration, and dermal healing by stimulating stem cell and fibroblast migration to sites of needed repair. These compositions and methods are useful for rejuvenating the skin and for treating some skin-related aging or other dermal damaging conditions, including wrinkle reduction and treatment of minor dermal wounds.

摘要:The present invention relates to skin care compositions comprising blends of camellia and feverfew serum fractions and/or kelp and parsley serum fractions. The skin care compositions also comprise a dermatologically acceptable carrier. The invention also relates to methods for increasing melanin production in skin by topically applying the skin care composition to areas in order to stimulate one or more steps in melanin synthesis and/or interrupt an inflammatory cycle.
