1. Chloasma: Chloasma is related to long-term sun exposure, which requires removing the cause of the disease and applying medication such as hydroquinone cream cream, vitamin A acid cream, etc. Vitamin C can also be taken orally. If necessary, it can be treated by chemical peeling and ruby laser treatment.
