Relaxing in cool water can help soothe inflammation, so try a cool bath or shower, then gently pat yourself dry and apply an unscented moisturizer with aloe vera, soy, or calamine. You can also try a hydrocortisone cream. To reduce inflammation further, apply ice packs for a maximum of 20 minutes or cold compresses to sunburnt areas. Damaged skin in these areas will be sensitive, so always wrap ice packs in a towel before using them.
