Tanning inside or out, does help to accelerate the aging process. Almost all types of lamps have UVAČ which breaks down collagen & elastin in the skin.
There are plenty of studies on this. This one from University of Maryland.

Processes Leading to Wrinkles. Even small amounts of UV radiation trigger the processes that can cause wrinkles:
Sunlight damages collagen fibers (the major protein that gives structure to the skin). Sunlight also causes accumulation of abnormal elastin (the protein that causes tissue to stretch) in the skin.
In response to this sun-induced elastin accumulation, the body produces large amounts of enzymes called metalloproteinases . One study indicated that when people with light to moderate skin color are exposed to sunlight for just 5 - 15 minutes, the metalloproteinase levels in their body remain high for about a week. |
Skin wrinkles and blemishes I do think these are a great additions to salons, especially the ones that incorporate the whole unit.
However maybe Roy or Stephen can give some sales tips for salons.
