What to do if skin turns red after sun exposure

Apply a cold compress by wrapping ice in a towel and placing it on the reddened area to lower skin temperature and relieve redness, swelling, and pain. Aloe vera gel or zinc oxide lotion can be applied to help repair the skin. If symptoms are severe, such as itching or allergic reactions, oral antihistamines like cetirizine or loratadine may be taken. Pay attention to daily skincare: keep the skin clean, avoid scratching, use lukewarm water when bathing, and minimize skin irritation.
