J-Cain Numbing Cream 500g

J-Cain® 500g is a topical anesthetic cream formulated with lidocaine to temporarily numb the skin before cosmetic, dermatologic, and minor medical procedures. It is widely used by aesthetic professionals to help minimize discomfort during treatments such as microneedling, laser procedures, dermal filler injections, botulinum toxin injections, mesotherapy, permanent makeup, and tattooing. J-Cain is intended for external use only and should be applied according to a healthcare professional’s instructions.
