摘要:
There are provided compositions which include a retinoid and preferably retinol; a dermatologically active acid; and a volatile base, such as ammonium hydroxide. Another embodiment of the invention includes compositions comprising a retinoid and preferably retinol; a dermatologically active acid; a volatile base; and a second neutralizing agent. There are also provided compositions which include a retinoid, a neutralized ammonium salt of a dermatologically active acid, and optionally a neutralized salt, other than ammonium salt, of an acid. Further provided are methods for reducing fine lines, wrinkles, skin roughness, and pore size and for increasing the clarity of a skin surface, cellular turnover, skin radiance, skin smoothness, skin permeation or collagen synthesis in a mammal in need thereof. Compositions as described above are administered topically to the skin of the animal.

摘要:
The present invention relates to a method of protecting skin from the oxidative effects of ultraviolet A radiation including UVA-induced lipid peroxidation. The method comprises topically applying to the skin an effective amount of a photoprotective composition that contains a lipophilic antioxidant that does not have appreciable absorbance near wavelengths of 320-380 nm.
摘要:
Skin care compositions comprising an oil-in-water emulsion base containing retinoids and possessing good physical and chemical stability, comprising a stabilizing system selected from the group consisting of: a) at least one oil-soluble antioxydant; b) a chelating agent and at least one oil-soluble antioxydant; c) a chelating agent; and d) a chelating agent and an antioxydant present in each of the oil and water phases of said emulsion.
