How much numbing cream is safe to use at a time for laser hair removal?
Doctor Answers 4
An 8 1/2 x 11 sheet of paper size is usually ok, but I wouldn't recommend applying any of this at home. Lidocaine toxicity is very dangerous and potentially deadly. Your provider should be able to apply a safe amount of lidocaine for you at the office.
Dosing topical EMLA
The typical adult dose of EMLA is 2.5 to 10 grams. It would be advisable not to exceed this. Most likely you will need to do half leg at a time ( thigh separate from lower leg). Extremities and torso we usually wait 6 to 8 weeks between sessions, face/bikini/underarms 4 weeks.

Lidocaine can be potentially dangerous especially if applied to larger areas for longer periods of time or occluded with a plastic wrap. In general, it is best to have it applied at the clinic unless your provider gives you explicit instructions for home use. I do not advise using this at home. A trained physician is the best person to be using Lidocaine. Please see a physician for laser hair removal treatment.
