Numbing creams are topical anesthetics that work to temporarily desensitize the nerves in the skin to reduce pain or discomfort during medical or cosmetic procedures. These creams are often used before procedures such as injections, tattoos, laser treatments, and waxing to help minimize the sensation of pain. Numbing creams typically contain ingredients like lidocaine, prilocaine, or benzocaine, which work by blocking nerve signals in the skin. It is important to follow the instructions for application and consult with a healthcare provider before using numbing creams to ensure safe and effective use.
