Study on skincare efficacy of compound extract from Chinese herbal medicines

A combination of in vitro experiments and human efficacy evaluation were used to assess the whitening, anti-aging and anti-allergic soothing efficacy and the irritation of a compound extract which was obtained from 5 kinds of Chinese herbal medicines. The results show that the compound extract is classified as non- irritation substance. Besides, it has strong ability to inhibit tyrosinase activity, scavenge DPPH/hydroxyl/superoxide anion radicals and inhibit hyaluronidase activity. After 4 weeks of using the emulsion containing the compound extract, it can significantly reduce skin melanin content and decrease the scores of skin UV spots, chloasma, wrinkle and texture. In addition, this emulsion containing the compound extract can effectively relieve the tingling caused by lactic acid. The above results indicate that this compound extract is a safe and effective cosmetics raw material which has good whitening, anti-aging and anti-allergic soothing efficacy.
