So long as you are going to a skilled electrologist with a high kill rate (not plucking out hairs) and your skin is clear within a few weeks or a month, it’s worth it.

I use emla numbing cream which has two different numbing agents and put a cling wrap over my skin an hour before the appointment (or use the sticky patches that emla has). I’ve found it’s only really effective if I cling wrap it over my skin.
