Feeling overwhelmed with laser hair removal

I want to get started with laser hair removal for my underarms and maybe Brazilian. I for sure want to get my underarms done because I’m tired of waxing and the having hair show up after a week and a half.

The problem is that I’ve been doing research on how to get started and it just feels so overwhelming. I feel like things can go wrong fast. And the r/laserhairremoval sub is filled with pictures of people getting burned.

I was hoping that sub had a guide but I can’t seem to find one. Does anyone here have some good tips?

I’m struggling to find unbiased info that’s not written by a cosmetic company
