The recovery time of red scars after burns is related to various influencing factors such as the degree of burns, personal constitution, recovery status and treatment method, etc. There is no clear clinical recovery time, which generally takes 3-6 months, and the lighter the degree of burns and the more timely the treatment, the faster the recovery, and vice versa, the slower the recovery. If the patient is a keloid, the red scar will take even longer to return to normal, or even not recover. If the patient is a small localized area scalded by hot water or hot food, the scalded skin surface does not form a raised scar and only a slight color change occurs, and recovery is usually faster. After timely rinsing with cold water and applying scald cream, recovery is usually possible in a few hours or days and no special treatment is needed. If the scald or burn is not treated in time and is more severe, the patient may damage the dermis and develop an uneven red scar, which is slower to recover, may take months or even years, and usually does not heal on its own. This type of red scars need to be diagnosed by the patient and treated with medication to remove the scars under the guidance of the doctor, commonly used medications include injectable ones such as tretinoin acetate, trenbolone, verapamil hydrochloride, interferon, etc. For patients whose medication is ineffective, surgery, radiotherapy, laser or freezing can also be chosen for treatment, which is more effective in treating red scars. During the treatment process, attention should be paid to a light diet and avoid spicy and stimulating foods such as chili peppers and mace. The scar area should be protected from the sun, avoid scratching, and avoid rubbing with harder clothes.
