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.
Remedies. I agree with dr. Barr. Cool compresses often. Aloe vera (aloe barbadensis) can reduce redness, pain, itching & swelling from a burn. It has anesthetic, anti-inflammatory & antibacterial / antifungal qualities. It can speed burn healing by stimulating growth of new skin. Non-steroidal anti-inflammatories and acetomenophen can be very helpful. Hydrate well and don't peel off any deep layers.
