High Pressure tanning beds combines high pressure quartz lamps with a tremendous filtering system to insure you receive 99% UVA tanning rays. High pressure lamps produce UVA & UVB in different ratios than conventional tanning beds; just enough UVB to produce the melanin required to tan and a lot of UVA to oxidize the melanin and turn it golden brown.
UVA rays, sometimes known as the “gentle tanning ray”, not only tan the very most outer layer of skin, but also tans the 2nd and 3rd sub-layers of the epidermis, giving a deeper, longer lasting tan. So even as your outer layer exfoliates, the layers beneath are still tan. UVA light does not cause the outer layer of skin to thicken.
