I can only say that despite exfoliating and shaving a day or two earlier and also washing right before epilating it doesn’t work on my upper thighs specifically. I’ve had good results on my lower legs and my arms, but my guess is that the hair is so thick it doesn’t pull it out all the way. I’m using a decent Braun epilator too so tgat shouldn’t be the issue.
I’ve tried both and the only difference it made is how much it hurt as it pulled out some of the hair. It didn’t seem to make a difference in result, ubfortunately. 😞
