Sun is the greatest benefactor to mankind however it is the skin's greatest enemy. Nothing wrought as much damage on the skin as the sun. Fairer skins are more prone to damage than their darker counterparts as they contain more melanin, which protects the skin against sunrays. However dark skins are also not immune to the damage. Sunlight not only effects the surface but it has the capacity to penetrate the skin and the living tissues of the lower layers. A few days of intense exposure to the sun can produce symptoms of aging and can even predispose it to cancer. The most damaging effect of the sun is that it dehydrates the skin causing it to become dry and rough and wrinkled, freckles, pigmentation and patches may also occur. An immediate reaction is expansion of blood vessels that is why skin looks flushed, red and gets tanned if stayed out in the sun for long. However sun is very good for children, as they require Vitamin D, which is abundant in sunlight for their growth and metabolism.
Protection against the sun is the only way to delay premature aging. This entails using an effective sunscreen all the time regardless of direct exposure to the sun. Long exposure should be avoided as far as possible. The chosen sunscreen should be sun that it not only blocks out the harmful part of sunrays but also prevents loss of moisture. Use re-hydrating creams and masks regularly to maintain the moisture content in the skin. As more than the sun if you don't take care of your skin you are it' greatest enemy.
