If it is just a few electrolysis is the best way, most permanent.
The new laser treatments work ok. I used it on my bikini and underarms. Takes about 6 treatments to really see a difference. I think it best for high hair growth areas, and then clean up strays with electrolysis. The new lazers don’t hurt. If the one you try hurts ditch it.
Lasers work but like @JLeslie says, they take a good 5 visits and they hurt. A lot. I did laser for my lady bits and armpits about 4yrs back and the results lasted 2 years but was worth to me enough to want to return and hurt myself some more. My body hair is jet black and my skin is light to where even if I shave, you see the hair under the skin so I understand your irritation.
Laser does not hurt with the new lasers. As I said, if it hurts ditch that laser, go for a different one. Ask ahead if it hurts. If they say it hurts like a rubberband snap, don’t open your wallet, go somewhere else.
