Antioxidants: One of the problems with sunburns is the production of free radicals. Studies have shown that sunburns cause a tremendous increase in free radical production, and damage. Vitamins A, C and E help destroy free radicals and heal the burn. Vitamin C also helps reduce the possibility of scarring. Now that you’ve taken care of the repair process, you’ll also need topical skin treatment for immediate relief. Aloe vera works well for some, but you might also try a shielding lotion. A good shielding lotion bonds with the outer protective layer of the skin to form a new layer that locks in natural moisture – sunburn causes serious dehydration so you need every drop you can get – and keeps out harsh chemicals and pollutants that could cause further irritation.
