J-Cain Cream 10.56% is a topical pre-procedure anesthetic used to make an injection procedure painless. The human body’s response to pain involves pore narrowing and vasoconstriction, which hinders the penetration of a needle or a cannula into the skin during injection and most likely results in skin injury (bleeding, edema, and irritation). The use of the J-Cain Cream 10.56% allows avoiding the adverse consequences of injections due to the high content of lidocaine. The product is approved by the KFDA, it does not cause allergies or skin burning sensations. J-Cain has one of the strongest numbing effects among local anesthetics in the world market.
