The black marks left on the face due to wounds can be promoted to subside through diet, medication and physical methods. 1. Diet: You can eat foods rich in vitamin C, such as cabbage, broccoli, spinach, tomatoes, oranges, lemons, kiwis, etc., which can effectively inhibit the activity of tyrosinase in the skin and reduce the production of melanin, which has a positive effect on the recovery of black marks left by wounds on the face. 2. Drugs: Under the guidance of professional physicians, you can choose to use topical vitamin E cream, Vitamin A acid ointment, oral vitamin B tablets, vitamin C tablets and other drugs for treatment. 3. Physical: If there is no significant improvement through diet and medication, you can choose to carry out intense pulsed light, laser, fruit acid skin resurfacing, photorejuvenation and other methods of treatment. Specific treatment methods need to be carried out under the guidance of a professional physician, not to use drugs privately, to avoid the impact on the health of the body.
