J-Cain 10.56% Lidocaine Cream is a topical anesthetic cream used to numb the skin before certain medical procedures or to relieve pain from minor skin irritations.

Composition:
 * Lidocaine: The active ingredient in J-Cain cream, lidocaine is a local anesthetic that works by blocking nerve signals to the brain, preventing the sensation of pain.
 * Other ingredients: J-Cain cream also contains inactive ingredients, such as water, propylene glycol, carbomer, and sodium hydroxide, which help to create the cream's consistency and stability.

Effects:
 * Numbness: When applied to the skin, J-Cain cream causes a temporary numbing effect, making the area less sensitive to pain.
 * Pain relief: J-Cain cream can be used to relieve pain from minor skin irritations, such as sunburn, insect bites, or minor cuts.
 * Anesthesia: J-Cain cream can be used to numb the skin before certain medical procedures, such as tattooing, piercing, or laser hair removal.
