Sun allergy is quite common. Polymorphous light eruption, or PLE, affects millions of people and comes with a host of irritating symptoms like redness, rashes, pustules, and blisters. There are other sun allergies as well, and these include solar urticaria, drug-induced photosensitivity, acne aestivalis, and others. The best offense against sun damage and sun allergies is a strong defense of prevention.
Skin hyperpigmentation happens when our skin produces too much melanin and leaves dark spots behind. These dark spots on the skin often develop on the face, neck, shoulders, and the hands. Melasma during pregnancy is one form of hyperpigmentation. Although this condition is usually harmless, it can be difficult to hide and embarrassing.
Age spots from sun are a discoloration of the skin caused by excessive melanin. Doctors aren’t sure why they occur, but frequent exposure to harmful UV rays, coupled with natural aging, are likely to blame. Anyone at any age can experience age spots, but they do not hurt, itch, or otherwise irritate.
