Abstract
Compositions, for example cosmetic or pharmaceutical compositions, and methods of increasing melanin formation on the skin or scalp employ liposomes including between 0.001 and 10 weight percent, with respect to the total weight of the composition, of tyrosine or a tyrosine derivative selected from the group consisting of an alkali metal salt of L-tyrosine, an alkaline earth metal salt of L-tyrosine, methyl L-tyrosinate, ethyl L-tyrosinate, and stearyl L-tyrosinate.
Claims17
A composition comprising liposomes including between 0.001 and 10 weight percent, with respect to the total weight of the composition, of tyrosine or a tyrosine derivative selected from the group consisting of an alkali metal salt of L-tyrosine, an alkaline earth metal salt of L-tyrosine, methyl L-tyrosinate, ethyl L-tyrosinate, and stearyl L-tyrosinate.
A cosmetic or pharmaceutical composition, comprising liposomes including tyrosine or a tyrosine derivative selected from the group consisting of an alkali metal salt of L-tyrosine, an alkaline earth metal salt of L-tyrosine, methyl L-tyrosinate, ethyl L-tyrosinate, and stearyl L-tyrosinate, the tyrosine or tyrosine derivative being included in the composition in an amount sufficient to stimulate melanin formation.
A cosmetic or pharmaceutical composition, comprising liposomes including between 0.001 and 10 weight percent, with respect to the total weight of the composition, of tyrosine or a tyrosine derivative selected from the group consisting of an alkali metal salt of L-tyrosine, an alkaline earth metal salt of L-tyrosine, methyl L-tyrosinate, ethyl L-tyrosinate, and stearyl L-tyrosinate.
A method of increasing melanin formation on the skin or scalp, comprising applying on the skin or scalp a composition comprising liposomes including tyrosine or a tyrosine derivative selected from the group consisting of an alkali metal salt of L-tyrosine, an alkaline earth metal salt of L-tyrosine, methyl L-tyrosinate, ethyl L-tyrosinate, and stearyl L-tyrosinate, the tyrosine or tyrosine derivative being included in the composition in an amount sufficient to stimulate melanin formation.
A method of increasing melanin formation on the skin or scalp, comprising applying on the skin or scalp a composition comprising liposomes including between 0.001 and 10 weight percent, with respect to the total weight of the composition, of tyrosine or a tyrosine derivative selected from the group consisting of an alkali metal salt of L-tyrosine, an alkaline earth metal salt of L-tyrosine, methyl L-tyrosinate, ethyl L-tyrosinate, and stearyl L-tyrosinate.
