A light skin burn would be classified as first-degree and affect only the outer layer of skin. Symptoms of a first-degree burn include reddening, some swelling and pain. If your burn blisters, it has moved beyond the first-degree stage into second-degree. Minor burns may not require professional medical care and rarely scar. If you are unsure of the extent of the burn or the source, you should see a doctor. However, if the burn is first-degree and covers a small surface area, it is possible to provide first-aid at home.
Evaluate the burn. This means determining the source and severity of the burn. If the burn is thermal or mild sunburn, treat this burn with first-aid at home. Skin exposed to a flame or hot object will have a thermal burn. Burns that cover large surface areas or that are on the hands, face, feet or genital area may have complications and require medical evaluation.
Cool the burn immediately with water. Go to the nearest sink and turn on the cold water. Place the burned area under the cold, running water. If the burn is not in an easily accessible spot, then place a cool compress on the area. Saturate a clean towel with cold water and lay it on the burn.
Cover the burn with an antibiotic ointment. Do not apply the ointment until the burn has been cooled. Applying grease or ointment to a hot burn allows skin to continue to burn. Once the cold water has done its job, protect the burn against infection with the antibiotic. It is not necessary to cover the burn. Simply smooth the ointment over the area and leave it alone.
Reapply ointment once or twice a day as needed. One application may be enough for very mild burns. Monitor the burn and look for signs of infection. Any open skin, red streaks or drainage may indicate infection. Go to the doctor if the wound is not healing and shows any sign of infection.
