Besides vitamin C, vitamins D and B3 have also been shown to provide valuable protection against skin damage and skin cancer. Vitamin D, which is metabolized when UV rays strike your skin, has actually been shown to reduce your risk of melanoma — the deadliest form or skin cancer.
Unfortunately, most dermatologists will tell you to stay out of the sun to avoid skin damage. But once you shun the sun, you prevent your body from working as nature designed it, and sun exposure is actually part and parcel of what helps keep skin cancer at bay.
Vitamin D is formed in your skin, and once activated in the liver and kidneys it influences the genes in your skin and helps prevent the type of abnormalities that ultraviolet light causes. As a result, sun avoidance becomes the factor that paradoxically can

According to Australian researchers, vitamin B3 (nicotinamide) may also offer protection for those who are prone to certain skin cancers

The pills also reduced the numbers of pre-cancerous lesions called actinic keratosis. These thick, scaly patches of skin were reduced by 20 percent among the volunteers who took nicotinamide after nine months of treatment.”
Those who took vitamin B3 started seeing results in about three months. However, the protection vaporized once they stopped taking the vitamin, so to reap the rewards, you’d have to continue taking it indefinitely. It’s thought that B3 works by helping repair DNA damage caused by excessive UV exposure, and by bolstering your immune system
