Some people with psoriasis find tanning at a salon can help treat flares. You might wonder about using tanning beds as a less costly psoriasis treatment. Tanning beds in commercial salons emit mostly ultraviolet A (UVA) light, not ultraviolet B (UVB) wavelengths. Though UVA brings out melanin to create the tan, it also penetrates your skin more deeply than UVB.
Phototherapy is the original psoriasis treatment. A form of UVB light known as narrow-band (NB-UVB) has been shown to be even more effective than UVB, and is increasingly being used by dermatologists. Tanning beds emit both UVA and UVB light, and the percentage of UVB varies widely by machine, from less than 1 to nearly 10. A tanning booth is similar to a tanning bed, but the person stands while tanning and the typical power output of booths is higher. Recently, high-intensity UVA-emitting lamps have been introduced to achieve more efficient tanning in shorter sessions; these have a much lower ratio of UVB to UVA, and are much less effective for the purpose of Vitamin D production.
