The wavelength-dependent penetration depth of light into human skin is an important mark for photobiologists helping to estimate ultraviolet (UV)-induced processes in the different skin layers. For example, knowing how much radiation of what wavelength is available at a certain depth in living human skin is one prerequisite for a valid risk assessment for skin cancer based on in vitro and

1 Some data suggests that melanoma and nonmelanoma (NMSC The skin undergoes certain changes when exposed to UV light, to protect against damage. The epidermis (the skin's uppermost layer) thickens, blocking UV light. The melanocytes (pigment-producing skin cells) make increased amounts of melanin, a brownish-colored pigment that darkens the skin, resulting in a tan. Most ultraviolet (UV) light from the Sun is blocked by the atmosphere before making it to the surface, but the American Cancer Society points out that UV light is still the main cause of the damaging effects of sunlight on human skin. Ultraviolet light therapy, also known as phototherapy, is the use of ultraviolet or UV light to treat skin conditions with its healing effects. Ultraviolet light treatments have been used for nearly a century worldwide to treat chronic skin conditions such as psoriasis, eczema and skin cancers.

To prevent possible serious injury, eyes and skin should not be exposed to direct or reflected ultraviolet light emitted by this lamp. This lamp is in Risk Group 3

Cancer Inst. , 90 ( 1998 ) , pp. 1278 - 1284 View Record in Scopus Google Scholar 2010-08-01 · In our study, a light source emitting 98.3% visible light was used to evaluate the effect of visible light on skin. In addition, melanocompetent volunteers with skin types IV–VI were used, which are different from the samples evaluated in the aforementioned studies.

Two types of UV light are proven to contribute to the risk for skin cancer: Ultraviolet A (UVA) has a longer wavelength, and is associated with skin aging. Ultraviolet B (UVB) has a shorter wavelength and is associated with skin burning. While UVA and UVB rays differ in how they affect the skin, they both do harm. The sun's rays provide warmth and light that enhance your general feeling of well-being and stimulate blood circulation. Some UV radiation is essential to the body as it stimulates the production of vitamin D. Vitamin D has an important function in increasing calcium and phosphorus absorption from food and plays a crucial role in skeletal development, immune function and blood cell formation. The effects on skin of exposure to UV light are known to everyone who has experienced sunburn, namely, erythema and edema followed by scaling and changes in pigmentation.
