Problems solved by technology

[0003] At present, the commonly used external preparations mainly solve the problem of pigmentation by inhibiting tyrosinase activity and melanocyte activity. The use of such products has certain potential risks and needs to be used under the guidance of a doctor; the milder active ingredients include azelaic acid, arbutin, vitamin C, etc., such preparations have problems such as the solubility of raw materials The preparation process is inconvenient, or the raw materials themselves are easily oxidized, and there will be unstable phenomena such as discoloration and odor of the preparation

[0004] In addition, pigmented dermatosis is a multi-inducing disease, and improving tyrosinase and melanocytes alone cannot achieve long-term treatment or alleviation of symptoms
