Many people got a bit too much sun exposure this past weekend as a result of a trip to the beach, an outdoor barbecue, or from just catching up on work in the garden. Most people thought enough about this sun exposure to slather sunblock on their exposed skin before going outside. But, that sunblock just might have caused a problem -- an itchy rash caused by an allergic reaction to the active ingredient in the sunblock. Sunblock allergy is not as rare as you think -- many people suffer from this unusual allergy -- which leads to an unpleasant dilemma. Should you risk getting a bad sunburn, or should you protect your skin by using sunblock, knowing that you'll pay the price with an itchy rash in 1-2 days? You may not have to make this unpleasant choice!
