Rep Power: 23 | The Tanning Process : Skin tanning results from exposure of the skin to ultraviolet radiation in the wavelength region between 260 and 400 nanometers. This region is conventionally subdivided into UVB short wavelength radiation (260 nm to 320 nm) and the longer wavelength UVA radiation (320 nm to 400 nm). Tanning results when melanin pigment is formed in the skin following exposure to ultraviolet radiation. There are two processes for tanning that occur. Immediate pigment darkening results from photo-oxidation of melanin already present in the melanocyte cells of the skin basal cell layer and is caused primarily by long wavelength ultraviolet radiation UVA. Delayed tanning results from production of new "packages" of melanin pigment called melanosomes. UVB radiation is much more efficient than UVA in this process. This is why small amounts of uvb are used in uva tanning lamps, The % of uvb can be from 1/2 a % all th way up to 9 %. High amounts of uvb are not needed to cause good tanning. And high uvb lamps will cause more burning or reddening of the skin. More tanning less burning. Its a good idea.
