Abstract
The present invention relates to a composition comprising the saponin fraction derived from the root of camellia sinensis, and more specifically, a composition which, by using the saponin fraction isolated after treating the extract of the root of camellia sinensis with an enzyme, can reduce the cellular toxicity over the conventional saponin fraction derived from the root of camellia sinensis to enhance stability to the skin, and can comprise the saponin fraction obtained by such method in much higher amounts to provide the more superior skin condition improvement effect.
