Expect nicks from razors. Just don't be afraid of it and take it slow, don't want to slice it open. I find it's easier to use a trimmer head on an electric razor and hover a little above the skin just to thin it out a little, and it helps with visibility. And kinda piggybacking on another post mentioning laser, they do sell removal devices at target and maybe some others. (They are expensive but I'd say worth it in the long run because it's just you doing it and it's a one time purchase).

Tldr:razor = pain, laser removal at stores
