Rash Reactions to Sun Damage and Exposure

Most of the concern related to sun exposure is regarding its long term effects, such as skin cancer and premature aging of the skin. For photosensitive people, unprotected sun exposure leads to a bumpy, itchy and sometimes painful skin rash. Though the symptoms of sun rash can be treated with drug store items, it is best to prevent the rash and damage to your skin.

  1. Polymorphous Light Eruption

    • Polymorphous light eruption, or PMLE, the cause of sun rash, is a condition in which exposure to ultraviolet light causes a red, itchy rash. Those who suffer from this disorder are considered photosensitive, or sensitive to sunlight. The Mayo Clinic (mayoclinic.com) explains that a sun rash will usually develop "after an episode of intense sun exposure," and is more likely to occur "in the spring or early summer with the first few exposures to sunlight."

    Symptoms

    • Web MD (webmd.com) explains: "the term 'polymorphic' refers to the fact that the rash can take many forms." PMLE can look like small pink or red bumps on the chest, arms or legs. In some people, the rash develops blisters or dry patches. PMLE can cause itching and burning at the rash site for days.

    Causes

    • Sun rash is often caused by prescription medication. Thoroughly read all information that comes with the drugs you are taking. The Mayo Clinic lists high blood pressure [medication], such as thiazides; antibiotics, such as tetracyclines; and nonsteroidal anti-inflammatory drugs, such as ibuprofen, as drugs that can cause sun rash.

      Another cause of sun rash and photosensitivity is exposure to chemicals found in soap, perfume and even sunscreen. These chemicals can make your skin more sensitive to the sun. Contact with celery, lemons, limes and some berries can also increase chances of developing a sun rash.

    Prevention

    • Sun rash can be prevented by limited exposure to the sun, especially during the hours of 10 a.m. and 4 p.m. when the sun's rays are the strongest. Twenty minutes prior to going outdoors apply a fragrance-free sunscreen with an SPF of at least 30 and reapply every two hours. Protect your skin further by wearing sunglasses, a hat and a long-sleeved shirt.

    Treatment

    • Aloe vera lotions and cooling gels that contain aloe vera help soothe the burning, itching and stinging associated with a sun rash and sun burn. An over-the-counter pain reliever such as acetaminophen will help lessen the pain and reduce the inflammation. For severe cases of sun rash, apply a cold compress to the irritated area. Web MD advises that sun rash sufferers stay out of the sun until the rash heals.
