A newly designed enzymolysis-fermentation combined method to dramatically enhance the actives level and skin benefits of traditional Chinese herbs (TCHs) was developed, biotransformation process under optimal reaction conditions can significantly transform molecular structures and obtained fermentation extracts can deliver better skin benefits on anti-aging, hydration and whitening. Analytical results showed that the ginsenoside Rg3, total sugar, polyphenols and flavonoids in fermented extract were 2~4 times higher than unfermented extract. In-vitro tests including DPPH radical scavenging activity, tyrosinase inhibition, cells proliferation and Hyaluronan-CD44 activity, have showed significant enhancement of efficacy, inhibition rate on DPPH antioxidation as example achieved over 60% improvement, which makes traditional Chinese herbs application more feasible. It is inferred that this study potentially enables the herbs to deliver required bioefficacy in cosmetic application.
