What Causes White Spots to Appear on the Skin When Developing a Tan?
White spots sometimes become noticeable on the body once the tanning process begins. These white spots may appear due to the presence of a fungus which lives on the skin’s surface. While the fungus is harmless, it does absorb UV light which would normally penetrate the skin. This fungus did not appear as a result of tanning; it merely becomes noticeable once tanning occurs. It can be remedied through the use of prescription drugs or some other topical lotions. Sometimes patches of skin which do not tan could be the result of genetic determination. The melanocytes in that certain area may simply not be efficient at producing melanin.
