Frequently a component of skin care products, resorcinol can be found in sunscreens as well as various anti-fungal creams and ointments. In conjunction with sulfur, resorcinol is applied as a treatment for conditions such as acne, eczema, dermatitis, and dandruff because it helps breakdown hard, rough skin. However, resorcinol products should be used in moderation because the substance is potentially irritating.
