3. Swelling of the skin
Sun poisoning can also make the skin swell. Fluid builds up within the tissue of the skin, and that buildup of fluid can make the skin swell. The inflammation can be mild and barley noticeable, or it can be severe and quite pronounced. Usually, the swelling of the skin that occurs with sun poisoning is accompanied by other symptoms, such as extreme redness of the skin, blistering, peeling, and pain.
If the swelling is severe and is not treated fast enough, it can cause lasting damage and affect the appearance of your skin. For example, it can speed up the aging process, resulting in premature wrinkles and/or sagging of the skin. If your skin is swollen, you can try to use home remedies to alleviate the symptom, such as cold compresses and soaking in oatmeal baths; however, medical care is your best bet, as swelling is a sign that your skin has been severely damaged by the sun.
