| Résumé : |
“Darkening of facial skin” known as “kusumi” in Japan is a phenomenon characterized by darkening of skin color and very fine wrinkle, and is thought to be a precursor symptom of photoaging. There are two methods to prevent “darkening of the skin” and photoaging ; the use of sunscreens products and the use of skin care products. The aim of the study was to research and develop an optimal skin care product that would protect the skin from “darkening of the skin” and photoaging without the use of synthetic organic sunscreen agents or powders. We therefore selected, from among the many natural Chinese herbs, two (extracts of Betula pendula and Engelhardtia chrysolepsis HANCE) that both contained potent anti-inflammatory and antioxidation properties, and prepared a combination cream of the two extracts. Results of long-term application showed the cream was effective in improving skin color and skin texture, and it thereby improved “darkening of the skin”. This cream has been supplied to many customers for actual use, and its effectiveness in improving “darkening of the skin” has been acclaimed on the market. Improving “darkening of the skin” means that existing skin not only become lighter, but it also leads to the prevention of future photoaging. |
