Re: Ladies: bleaching your face
If your skin was too sensitive for waxing and threading then bleaching would not be recommended as it is much harsher on your skin than probably any other hair removal method.
If you're getting spots after waxing and threading then it's probably due to blocked pores, as when you remove hair from the root you leave the pore exposed and it can easily get bacteria build up which causes spots. Make sure you wipe something like aloe vera gel, or any mild toner over your face after waxing/threading and then apply a light moisturiser. It should do the trick.
