Frequent Sunbathing or Tanning
Though sunbathing seems really fun, it may cause age spots, freckles, as well as brown warty lesions. Our skin becomes exposed to UVA, UVB, and infrared-A rays which cause wrinkles and fine lines. Moreover, too much exposure to the sun may lead to skin cancer. If you are fair skinned, 40 years of age, and often go outdoors, check your skin regularly for spots.
