Shades,
it sounds more painful then it actually is. I had about 6 session (full Bikini, Brazilian) and OK the perineum it a bit more touchy but so can be the bum-crack.
Electrolysis is more painful in general and A LOT more so on the upper lip area.
Laser is not such an issue, but in any case if similar to my hair roots, they will re-grow. Thankfully A LOT thinner.
There you are,
Axelle
