Great advice above! I'd add that wearing loose, comfortable clothing to your appointment is a game-changer, especially for areas like underarms or bikini line. You don't want tight fabrics rubbing against treated skin afterward. I learned this the hard way after my first session. Also, if you're nervous about pain, you can take an over-the-counter pain reliever about an hour before. When I was getting my treatments done at laser hair removal service, they provided detailed prep instructions and even called the day before to remind me. Having a good clinic that communicates well makes such a difference in the whole experience!
