Pigmentation cannot be cured. Pigmentation is a common pigmentation skin disease that occurs on the human face, which is difficult to get rid of completely with the current medical level, but can be controlled and faded through treatment. Pigmentation is usually related to cosmetic residues, ultraviolet radiation, poor dietary habits, mental stress, pregnancy, long-term use of birth control pills and other factors. Therefore, when patients have long spots, they should actively avoid the triggering factors. For example, patients should pay attention to sun protection, use spot lightening products to brighten skin tone; improve lifestyle, such as regular life, avoid staying up late and ensure sufficient sleep; adjust diet and nutrition, increase the intake of vitamin C rich food. In addition, women can consult the dermatology department and choose laser spot removal and photorejuvenation treatment, which can achieve better results. If laser blemish removal is used, patients should pay attention to not touching water at the local crust after surgery to prevent infection, do a good job of sun protection, and do not use any cosmetics with irritation.
