The remaining part of the dermis usually allows healing without scarring, but if the burns are extensive slight scars can remain. They can cause tissue to blister or turn black. Get out and stay out-of the sun. Cool the burn, by applying cool, wet compresses for 10 minutes at a time several times daily. A cloth soaked in cold tea or milk, or a mask of plain yogurt, can help.
Cold baths can help, too.
Some dermatologists advise adults take two aspirin every four to six hours during the first 24 hours after exposure to reduce inflammation. Calamine lotion or anesthetic lotions or sprays can soothe. When in doubt about using a product, consult your pharmacist or physician. Give acetominophen if temperature is above 101 degrees. Tepid soaks in clear water may cool skin.
