If a burn from oil leaves a red mark, there's no need for the patient to panic. The red mark remains because the injury occurred recently and the tissues have not fully repaired themselves. Generally, after about six months, the red mark will gradually fade. Patients should avoid rubbing the area, scratching it, and consuming spicy or irritating foods. Alcoholic beverages should be avoided, and foods rich in vitamin C should be consumed more. If you want to speed up the fading of the red marks, you can pierce a vitamin E capsule and apply the liquid inside to the remaining burn mark, gently massaging it for about ten minutes, twice a day. This method can be effective.
