摘要：
A composition for topical application is provided containing ascorbic acid and at least one polyol, the latter being present in an effective quantity to obtain a water activity value of the composition which is lower than or equal to 0.85, and at least one structuring agent chosen from polymers and oils, with a view to stabilizing the ascorbic acid. In such a composition ascorbic acid retains its effectiveness over the course of time. The composition obtained can be employed for treating and/or caring for the skin.
