White spots from tanning can occur for a number of reasons. The four primary reasons which I’ll discuss here are pressure points from the positions in which you tan, side-effects of medications, skin fungal infections, and genetics-related or overexposure-related skin pigmentation conditions.

One of the most common and thankfully least dangerous causes of white spots from tanning are pressure points. People relate tanning to relaxing and thus remaining still. So inevitably, their bodies will rest on pressure points where their circulation will be reduced. Locations such your hip bones and shoulder blades tend to develop these sorts of white spots from tanning most often. I suggest rotating and moving more during your tanning. Of course, this is precisely the kind of problem you wouldn’t have if you chose to sunless spray tan rather than baking yourself in the sun or a tanning bed.
