Melanin treatment on the face can be treated by a combination of medication regulation, photochemotherapy and life diet regulation. General medication can choose drugs that inhibit tyrosinase inhibitors, or drugs that inhibit black synthesis, such as retinoic acid; you can also choose skin peeling agents, such as hydroquinone cream; you can also regulate the metabolic problems of the skin through Chinese herbal medicine. The effect of photochemotherapy is also better. The principle of this treatment for melanin is the same as that for melasma, both of which activate the skin tissue to metabolize melanin through the spectrum. Generally, in life, it is recommended to avoid sunlight and require outdoor application of sunscreen to avoid aggravating the accumulation of melanin, and usually pay attention to reasonable diet to increase immunity.
