How can i cure a sun burn?

Cool and moisturize: Topical cooling will relieve pain immediately. Refrigerated aloe works best. For highly sensitive areas a topical anesthetic can be used under a physicians direction. Oral antinflammatories such as Ibuprofen can provide relief over the first few days. After cooling apply a rich moisturizer such as aquaphor or biafine.

Simple Care: Sunburn is response of the tissues to injury from solar radiation. It is simply inflammation which means increase blood flow to the area to promote healing. Do not use ice as this can injure already injured skin. Cool water soaks can help as can taking anti-inflammation medicines like Motrin or advil (ibuprofen). Avoid any further damage as this can cause scarring . Good skin cream applied daily/gently helps.
