Abstract: The present disclosure relates to a cosmetic composition for increasing skin exfoliation, which contains an exfoliating agent and contains no or 10 wt % or less of a polyol humectant based on the total weight of the composition. The composition of a cosmetic material is selected such that the affinity of the exfoliating agent to keratin-binding proteins can be retained and, thus, the provided exfoliation-increasing effect can be achieved reliably. Furthermore, the cosmetic material does not cause irritation and, in particular, can retain the superior exfoliating effect of serine or carnitine.
