Active Ingredients
The most active ingredient of numbing cream is lidocaine. Lidocaine is a drug obtained from the Coca plant. It is actively present in almost all numbing creams. Lidocaine acts as a nerve-deadening drug and prevents nerves from signalling the brain. Lidocaine is a topical drug that stays on the upper layer of the skin and doesn't absorb deeper, so you may feel a bearable amount of pain. Other active ingredients in a numbing cream are Benzocaine, tetracaine, Pramoxine, and Dibucaine.

Benzocaine and tetracaine act as nerve-blocking agents. They are combined with lidocaine to enhance the numbing effect of the cream. However, they don't make magic happen by completely numbing the pain. They make the pain bearable during the procedures.

Other drugs like vasoconstrictors are more effective in numbing the pain as they constrict the blood vessels and reduce the bleeding. Vasoconstrictors are usually combined with other active ingredients. The effectiveness of the numbing cream depends on the combination of the active agents used.
