Also known as “solar lentignes,” age spots are very common in adults over 50 . But can also occur to those much younger. Despite their name (age spots) they are in fact due to accumulated sun exposure. They are well -defined, uniformly colored, brown or gray, and appear on the sun exposed skin areas like the face, neck, shoulders, decolletage and hands. Conditions like pregnancy, vitamin deficiencies , weak liver functioning may also lead to this problem.
