The scar on the face can gradually fade away with time. Daily skin care, using topical medication as prescribed by the doctor, or laser treatment can promote the fading process. 1. Daily skin care: pay attention to the damaged area of the skin sunscreen, avoid using hands or other objects to stimulate the damaged skin, so as not to cause skin infections. Eat more vitamin-rich fruits and vegetables, such as apples, oranges, spinach and so on. 2. Topical medication: Ascorbic acid cream ointment can be used to treat local skin color redness after trauma, which can better promote the receding of red marks. 3. Laser treatment: patients with more serious red marks can go to the regular hospital for laser treatment. The laser can close the capillaries of the skin red marks, so as to play a role in promoting the receding of the red marks. The above symptoms are recommended to be treated in the hospital as prescribed by the doctor, and the above drugs should be used as prescribed by the doctor.
