I know performing laser hair removal is contraindicated after inital injection of lidocaine (may cause burning of solution)
Should you wait at least an hour before procedure if you are having lidocaine injections
One need only wait about an hour for topical applications of lidocaine to be fully effective. If you have injections, electrolysis may be performed (and should be performed) begining in 5 minutes so as to maximize the amount of treatment time.
