It’s the build-up of dead skin cells that block your hair follicles and cause razor bumps and ingrown hairs when you shave.
So exfoliating the dead cells away keeps your follicles clear - and stops ingrown hairs from forming.
As well as improving the overall smoothness of your face, it also stops breakouts occurring.
Exfoliation is especially good for black skin as it gets rid of the dry skin cells that can make dark skin look ashy and clog your pores.
And if you have a beard, exfoliation will keep beard dandruff at bay, improve the texture of your skin and keep your hair follicles clear and healthy, encouraging strong beard growth.
