Why is #tanning #damaging to your skin? When ultraviolet light - TopicsExpress



          

Why is #tanning #damaging to your skin? When ultraviolet light penetrates the epidermis it stimulates melanin, the substance responsible for skin pigmentation. Up to a point, the melanin absorbs dangerous UV rays before they do serious damage. Melanin increases in response to sun exposure, which is what causes the skin to tan. This is a sign of skin damage, not health. Sunburns develop when the UV exposure is greater than the skins natural ability to protect against it.
