Ultraviolet (UV) radiation that reaches the Earth’s surface is in wavelengths between 290 and 400 nm (nanometers, or billionths of a meter). This is shorter than wavelengths of visible light, which are 400 to 700 nm. People and plants live with both helpful and harmful effects …

The major acute effects of UV irradiation on normal human skin comprise sunburn inflammation (er … Bright light activates the constriction of the pupil and the squinting reflex to minimize the penetration of the sun’s rays into the eye. However, the effectiveness of these natural defences in protecting against the dangers of UV radiation is limited under extreme conditions such as sunbed use or strong ground reflection from sand, water and snow. The skin serves as a protective barrier to various environmental factors, such as ultraviolet (UV) radiation, air pollution, and environmental hormones. These environmental factors enhance the aging of the skin. Skin aging is divided into intrinsic (chronological) and extrinsic processes that involve increased wrinkling, sagging and laxity. 2020-04-25 2020-03-27 2020-10-01 2020-05-29 It is true: ultraviolet (UV) light — a culprit behind sunburns, wrinkles and skin cancer — does offer benefits for some skin conditions.

Ultraviolet Light Treatment Definition Ultraviolet light treatment uses a particular band of the nonvisible light spectrum to treat psoriasis and a variety of other skin diseases. It can be used alone or in combination with other medications applied directly to the skin or taken internally.

Sun avoidance, dwelling far away from the equator, and lifestyle are some of the factors that limit exposure to UVB light on a Another form of light therapy for psoriasis involves the use of psoralens (medications that make the skin sensitive to light) followed by skin irradiation with ultraviolet A (UVA) light.
