Is there any place for herbs or vitamins?

BETA-CAROTENE
Taking beta-carotene orally seems to modestly reduce the risk of sunburn in individuals who are sensitive to sun exposure. There is some evidence that 25 mg of mixed beta-carotene daily for 12 weeks reduces skin redness after exposure to UV light in sun-sensitive individuals. However, beta-carotene is unlikely to have much effect on sunburn risk in most people. Also, it doesn't seem to reduce the incidence of skin cancers associated with sun exposure.
MELATONIN
Applying melatonin topically seems to prevent sunburn from ultraviolet (UV) light exposure. When applied prior to UV light exposure, melatonin seems to significantly decrease sunburn. In one study, topically applied vitamin E in combination with vitamin C and melatonin, provided modest photo-protective effect when used prior to UV exposure, but had no effect when used during or after UV exposure

VITAMIN C (ASCORBIC ACID) and VITAMIN E
Taking vitamin C orally in combination with vitamin E seems to prevent ultraviolet (UV) radiation-induced sunburn. This effect is not found when vitamin C is used without vitamin E. Applying vitamin C topically, in combination with vitamin E and melatonin, also seems to prevent ultraviolet (UV) radiation-induced erythema (sunburn). Topical vitamin C in combination with topical vitamin E and melatonin seems to provide modest photo-protective effects when used prior to UV exposure.
