How long does it take for redness to return to normal after a burn injury to be determined by the individual, the average patient’s redness will return 1 week to 6 months after the injury, and some patients may need more than 1 year to recover. At present, there is no clear clinical information to show how long it takes for redness to return to normal after burns, and the time it takes for redness to return to normal needs to be judged according to the severity of the burns. If the patient has a Ⅰ ° burn resulting in localized redness of the skin, it will usually return to normal within 1 week. If the localized skin redness is caused by a superficial II° burn, it usually returns to normal 2 weeks to 3 months after treatment. If the patient has a deep II° or III° burn, the localized redness of the skin after treatment is a sign that scarring is about to increase and will be difficult to recover on its own, requiring early scar preventive treatment to minimize scarring as much as possible. It is recommended that patients need to consult a doctor in time after the redness of the burned skin, and the doctor will judge the specific recovery time according to the severity of the burned skin.
