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.
Because symptoms are similar, telling the difference between windburn and sunburn can be difficult. Skin-damaging UV rays cause sunburn, while cold and windy weather causes windburn. Sunburn poses a long-term health risk, and may even cause skin cancer. While windburn is harmless in the long-term, but still leaves your skin red and irritated after a day of hiking, skiing, or even just walking in the park.
