Noooo !!! DONT !
Any form of hair removal makes the hairs grow back thicker, epilating/ waxing only lets the hair grow back slower so you dont have to keep shaving it, since it rips it off from the root so therefore it will take a while, until it grows back, but it will still be thicker !
So if you got a facial hair problem, just bleach it, it will be so unnoticeable, I use 'Jolen' & it works wonders, I hope I helped :)
