Too much sun exposure can cause significant damage to human skin, even though most people enjoy the warmth and light it provides. When exposed to direct sunlight, skin loses its natural ability to retain lubricating oils, which causes areas of exposed skin to become dry and cracked. UV radiation from the sun can also cause burning and long-term changes to the structure of the skin.
Sun damage can appear on the skin in various ways, but dark spots and freckles are the most common. Most people want to look and feel their best for as long as possible. However, this is a difficult task because of the ageing effects of the sun and the decreased collagen production that occurs with age.
