Getting tan is a respond of your body to UVA and UVB rays. When your skin is exposed to sun, it starts to produce a pigment called melanin that colors our skin. Its a response of our bodies and sign of damage that has been done by exposing our skin to sun.
Sunscreen, also known as suncream or sunblock, is designed to offer fuller protection against both UVA and UVB rays. Sunscreen prevents sunburn, reduces risk of skin cancer, and helps prevent early signs of skin aging. Some work by scattering the light, reflecting it away from your body.

Research soon showed that ultraviolet A rays (UVA) also increase skin cancer risk. While UVA rays don't cause sunburn, they penetrate deeply into skin and cause wrinkles. Its estimated that up to 90% of skin changes associated with aging are really caused by a lifetime's exposure to UVA rays.
Which sunscreen is right for you?
