Abstract
A cosmetic composition comprising: (a) 2-mercaptonicotinoyl glycine; (b) acyl glycinate surfactant; (c) a salt providing divalent cations having a charge density of about 40 to about 200 C/mm3 and a water solubility of at least 400 g/L; (d) anionic polymer; (e) glycerin; (f) water; and (g) reducing agent. The cosmetic composition is particularly useful in a method for brightening skin, depigmenting skin, treating hyperpigmentation of skin, treating melasmic skin, or evening skin tone.

A cosmetic composition comprising:
- (a) about 5 to about 15 wt. % of ascorbic acid;
- (b) about 5 to about 25 wt. % of one or more acyl glycinate surfactants;
- (c) about 0.05 to about 5 wt. % of one or more salts providing divalent cations having a charge density of about 40 to about 200 C/mm3 and a water solubility of at least 400 g/L;
- (d) about 0.5 to about 6 wt. % of one or more anionic polymers;
