This product is used on the skin for the short-term relief of pain and itching from certain skin conditions (such as sunburn, scrapes, minor cuts/burns/skin irritation, insect bites). Benzocaine is a local anesthetic that works by causing temporary numbness/loss of feeling in the skin. Menthol works by causing the skin to feel cool and then warm to distract you from feeling the pain and itching.
