yes. in some people sunscreens containing paba (para-aminobenzoic acid) can actually heighten the risk of suffering from sunburn. other ingredients in sunscreens may also increase the risk of a skin reaction in certain people. anyone can determine the suitability of a particular sunscreen without risk of serious harm by: clothing his or her body fully except for a small patch of skin. applying sunscreen to the skin patch and exposing it to sunlight. if a reaction occurs the user should not use that product. he or she should try another product.
can sunscreens cause a skin reaction?
