Application:
Alpha-arbutin is a chemical, similar to arbutin, that inhibits the production and deposition of melanin, and removes pigmentation and freckles. Studies have shown that -arbutin can inhibit the activity of tyrosinase at a relatively low concentration, and its inhibitory effect on tyrosinase is better than that of arbutin. Alpha-arbutin can be used in cosmetics as a whitening agent.
Storage:
Stored in cool dry conditions in well sealed containers
