The difference between lidocaine gel and cream is the difference in dosage form, while the active ingredients are the same. The excipient of the gel allows the drug to adhere evenly to the mucous membrane and has a faster onset of action, about one minute, and delays the release of the drug, which is commonly used in cystoscopy and male urethral surgery. Cream is able to penetrate the dermis layer of the skin, the effect is slower, about 20 minutes to an hour, applicable to all kinds of superficial skin surgery, needle puncture, ulcer debridement, medical aesthetic surgery and skin itching, etc., to play an analgesic effect. Lidocaine is a local anesthetic, either in the form of an injection, gel or cream, which provides a fast and safe nerve anesthetic effect and is widely used in clinical practice.
