I bought the Veet Version for my top lip and chin. I normally have to epilate/pluck/trim using a wand on a daily basis.
Shaved the area as required (eeek!) zapped on the lowest level and apart from one area which I couldn't zap due to a hormonal spot, I haven't had to do anything to it at all. I need to repeat at their stated levels, but I'm so impressed. Planning my underarms tomorrow.
I have had laser and IPL on my underarms and bikini line in the past few years.
The laser is by far the better treatment. After a course of laser on my bikini line I was hair free for many years. It doesn't last forever -so I booked in for IPL to zap the new growth. IPL did not do it for me. Perhaps having a home IPL gun would work, but going to a salon for a course of treatments would need to be repeated quite frequently ime.
If you can get laser instead then I think you will find it more effective.
