Although hydroquinone has long been the standard skin-whitening agent throughout the world, its reputed cytotoxicity prompted a ban in 2000 in Europe and strict regulation in Asia. In response, in addition to combination treatments that include but rely less on hydroquinone, the armamentarium has expanded to include a wide range of active constituents extracted from plants, including aloesin, arbutin, flavonoids, gentisic acid, hesperidin, licorice, niacinamide, yeast derivatives, and polyphenols, which inhibit melanogenesis through varying mechanisms without inducing melanocytotoxicity (J. Investig. Dermatol. Symp. Proc. 2008;13:20-4). This column will focus on recent research related to the skin-lightening activity of aloesin.
A moderately high-molecular-weight C-glycosylated chromone naturally derived and isolated from aloe vera, aloesin has been found to dose-dependently inhibit tyrosinase by blocking both the hydroxylation of tyrosine to 3,4-dihydroxyphenylalanine (DOPA) and oxidation of DOPA to dopaquinone, as well as melanin production in cultured normal melanocytes (Pigment Cell. Res. 2002;15:335-40). Notably, aloesin (2-acetonyl-8-beta-D-glucopyranosyl-7-hydroxy-5-methylchromone), which is difficult to synthesize, and a few chemically related chromones, particularly the 5-methyl-7-methoxy-2(2´-benzyl-3´-oxobutyl)-chromone, have been shown to display a more potent inhibitory effect on tyrosinase than arbutin and kojic acid (Dermatol. Clin. 2007;25:353-62; Chem. Pharm. Bull. [Tokyo] 2002;50:309-11; Pigment Cell Res. 2006;19:550-71). The activity of aloesin in relationship to tyrosinase is important because tyrosinase is the rate-limiting enzyme in melanin production, and thus directly impacts skin pigment formation.
