Hard to say: If the rash occurs only on sun exposed area, one needs to consider photosensitizing from lotion applied or drug taken. Some ingredients in sunscreen can also induced photoallergic reaction. Try changing sunscreen PABA-free or one with a different active ingredient. Topical cortisone may help
