    摘要: The invention relates to a cosmetic or dermatological composition containing at least one precursor of a substance whose active form is sought for its cosmetic activity. One of the applications of the invention relates to compositions capable of rapidly imparting to the skin a color similar to that obtained on prolonged exposure to ultraviolet, solar or artificial radiation, while at the same time avoiding the drawbacks of such an exposure (erythema, burning, loss of elasticity, appearance of wrinkles, premature ageing of the skin, and the like).
