You might expect that some fragrances in personal care products could cause skin allergies, but did you know that most common preservatives also cause allergies? Recent studies suggest that current patch tests may not detect the problem product, so if itchy rashes or blisters on the skin continue without explanation, talk to your doctor about ensuring any product you suspect is included in the diagnosis.

Your dermatologist may have access to databases for finding safe products based on your range of allergies, or you can do your own research on databases such as cosmeticsinfo, maintained by the personal care products industry, or skindeep, maintained by the NGO Environmental Working Group.
