Friction Barrier Cream contains tea tree oil which is an antiseptic, anti-fungal, antibacterial oil, so it is acting as a treatment to help clean the skin of impurities, which may sting if the skin is irritated or chafed. The shea butter in the cream will help lessen the chafing and the more the cream is used as a barrier the softer and less chafed the area should become, so the stinging or burning sensation should get a lot less or disappear completely.
