How long it takes for a burn on the face to return to normal color cannot be generalized due to the varying degrees of the patient’s condition. Mild burns can gradually return to a roughly normal color in a few weeks. Severe burns are difficult to predict and can even leave scarring for a long time. Burns are injuries caused by heat, such as flames, hot vapors, hot metals, etc., or may be the result of chemicals, such as acids, alkalis, or phosphorus. If the burn is mild, it usually heals within two weeks and gradually returns to a more or less normal color over several weeks. Some superficial second-degree burns may continue to have discoloration or depigmentation. In deep burns, scarring can occur and requires aggressive treatment to minimize scarring. In the event of facial burns, the patient should go to a hospital and cooperate with the doctor to take treatment measures.
