Ultraviolet (UV) phototherapy is the use of specific wavelengths of the sun’s natural spectrum for the treatment of photoresponsive skin disorders such as psoriasis, vitiligo, and atopic dermatitis (eczema); and for the treatment of Vitamin D deficiency. Phototherapy devices create either the short wavelength Ultraviolet-B (UVB) rays or the longer rays of Ultraviolet-A (UVA). UV light produces biological reactions within the skin that lead to clearing of the lesions. UVB is the only waveband of light that produces Vitamin D in human skin.

Quick facts about Vitamin D
We All Need Vitamin D
Over millions of years of exposure to the sun, the human body has evolved the need for UVB and Vitamin D for general health. It is a biological certainty that UVB makes Vitamin D in human skin and nearly every cell in the human body has a Vitamin D receptor.
Skin Pigment Is Nature’s Sunscreen
The darker the skin, the more UV-blocking melanin it contains. Over thousands of years, the humans that migrated north from Africa into less-sunny Europe had their skin naturally lighten so more UVB could penetrate and make the Vitamin D they needed.
Vitamin D Tablets Don’t Work For Everyone
Modern lifestyles inside buildings and the use of sunscreens prevent most of us from getting adequate Vitamin D from the sun. Oral Vitamin D tablets can maintain levels for most of us, but not for those with absorption problems in the gut.
Solar UVB Is Inconsistent
The UVB content of natural sunlight is highly variable, making proper dosing difficult, along with greater risk of skin burning. UVB from the sun varies with latitude, time-of-day, time-of-year, altitude, cloud cover, and pollution.
UVB Provides Photoprotection
UVB creates new melanocytes in the skin which are ready to produce melanin and provide photoprotection when the skin receives natural sunlight. This is of particular value to those that occasionally travel to sunnier climates.
Too Far North?
The further north you are, the less UVB reaches the earth, especially in the winter. This is because the tilt of the earth makes the sun’s rays travel longer through the atmosphere, which filters out the shortest wavelengths first: UVB.
Tanning UVA Won't Do
Only UVB makes Vitamin D in the skin. Cosmetic tanning beds and some UV equipment specifically marketed for Vitamin D produce almost entirely UVA with only a small amount of beneficial UVB.
Sensible Exposure Means Excluding Some Skin Areas
The risk of premature skin aging and skin cancer increases with cumulative lifetime repeated exposure of UV to a specific skin area, so it makes sense to exclude any such skin areas from further UV exposure, such as the face and chest.
