When new skin grows after a burn, you need to protect yourself from the sun and avoid bumps. Paying attention to sun protection after burns can reduce the new skin pigmentation, and can reduce the growth of scars. And because the new skin is more delicate, bumping may cause the wound to bleed again, resulting in the formation of scars. Physical sun protection is recommended, such as wearing sun hats and long-sleeved clothing. Avoid using sunscreen and other chemical sunscreen methods, so as not to cause irritation to the new skin, causing dermatitis or stimulation of scarring. If the wound scar appears to be hyperplasia and other conditions, you can consult the regular medical institutions for medical aesthetic, such as through laser and other ways to remove scars. It is recommended that patients pay attention to healthy lifestyle while protecting the new skin, and if discomfort occurs at the wound, it is recommended to consult a doctor for a clear diagnosis in a timely manner.
