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.
Melasma is a common skin condition that causes dark brown spots and patches. It is caused by a variety of factors, including genetics, certain hormones and medications, exposure to the sun, and other high sources of heat. While it is difficult to treat, melasma can be prevented by avoiding the sun’s harmful UV rays and other extreme heat sources.
Sun sensitivity, sometimes referred to as a sun allergy, is an immune system reaction that is triggered by sunlight. Sun sensitivity reactions include solar urticaria, chemical photosensitization, and polymorphous light eruption and are usually characterized by an itchy eruption on patches of sun-exposed skin.
