Will Sunscreen Work Even After Getting Burned?

Sunburn causes inflammation of the skin and should be kept out of the sun until it is healed. Sunscreen is best used as a preventive measure, while other treatments are preferred for use on burned skin.

  1. Characteristics

    • Sunburns can commonly range from first-degree to second-degree burns. The symptoms of a first-degree burn include redness and pain. Second-degree burns include severe peeling and blistering, and can be considered a medical emergency if they cover a large area of the body.

    Proper Use of Sunscreen

    • Sunscreen with a minimum SPF of 15 can effectively prevent a sunburn. An ounce, or approximately the size of your thumb -- can be used to cover the entire body. Sunscreen should be applied as a thick layer and thoroughly on the skin. For best results, sunscreen should be applied 30 minutes before sun exposure and should be applied throughout the day for all-day activities in the sun.

    Proper Sunburn Treatment

    • First-degree sunburns are best treated with lukewarm showers, moisturizers and over-the counter hydrocortisone creams. Avoid products that include the suffix "-caine" (such as benzocaine), because these may worsen the inflammation. Anti-inflammatory pain relievers can also help reduce the pain of sunburns. Do not break any blisters caused by sunburn. The blisters serve as a natural protectant for the area, and bursting them delays healing. Wear gauze or blister guards over these areas to ease the healing and deter the urge to break the blister. Seek medical attention if sunburn is accompanied by chills, fever and a headache. Wear loose-fitting clothing, or protect the skin with gauze for second-degree burns.
