this was my first time! i did one leg a few nights ago and finished the other leg today. the first leg was crazy painful, took me hours, working up the nerve to press on after each pass. the other leg went a bit quicker; by then i was mentally used to the pain so i was able to go quicker. allegedly the first time epilating is the worst, but then your skin physically grows accustomed to the sensation so the next time you do it, it won't hurt as much. i can't verify that yet tho lmao

re: the eyebrow thing, yeah ive had my eyebrows plucked once a long time ago, and it hurt so much i couldn't stop tearing up. i haven't done it since then though so i genuinely can't tell (⁠;⁠ŏ⁠﹏⁠ŏ⁠)

edit: for reference i used the Braun silk épil 9 epilator. comes with 2 speeds and 3 attachments: a massage roller cap, a skin close cap, and a trimmer/shaver head. the massage head i used for the most part since it is a little more comfortable, but after i went back over with the skin close cap to get everything i missed or couldn't see.
