Nature’s makeup not only makes you look beautiful, it also helps protect your skin against the effects of ultraviolet light. Exposure to sunlight increases the amount of melanin in the skin in order to protect the skin from damage. Individuals with greater levels of melanin in the skin, such as those with dark complexions, are better equipped for protecting their skin from the sun, as the darker the skin is, the more melanosomes present.
This is why sunscreen is heavily used among pale populations, but is not as necessary for those with dark skin. Darker skin hinders UVA rays from penetrating, and as such, darkerskinned individuals tend to show fewer signs of aging in their skin and have lower risks of developing skin cancer. A final factor that influences your risk of skin cancer is the presence of DNA repair enzymes in the skin.
These enzymes protect skin against damage from free radicals, such as those produced when the skin is exposed to sunlight. Normally, these repair enzymes keep the DNA in good shape. People who lack the genes for these repair enzymes have a higher risk of developing skin cancer. Unfortunately, you cannot improve your DNA, but you can stop free radicals by consuming the antioxidants available in many fruits, vegetables, grains, seeds, and nuts.
Eating antioxidant-rich foods can help reduce everyone’s risk of skin cancer. In fact, antioxidants protect your entire body from free radical damage. By simply fine-tuning your diet to include healthy, antioxidant-laden foods, you can give your skin the self-defense it needs to fight damage and aging.
