Numbing Cream FAQs

Yes. When applied as directed, Zensa 5% lidocaine numbing cream delivers a numbing sensation that lasts approximately 2–3 hours on average. Many assume a higher percentage automatically means better results, but effective absorption matters just as much as concentration. For maximum effectiveness, apply a half-inch thick layer and cover with an airtight dressing before your procedure.

Topical anesthetic cream is used to numb the skin before cosmetic procedures such as:

• Microneedling
• Hair removal

• Tattoo removal
• Permanent makeup
• Piercings. 

These creams help reduce surface pain so the experience feels more manageable, comfortable and easier to endure.

Numbing cream contains lidocaine, a local anesthetic that blocks the nerve signals responsible for pain. When applied properly, lidocaine numbing cream desensitizes the surface of the skin without affecting deeper pressure or movement.
