Yes, for people with dry or lifeless skin. One to three times per week at most, cut back if your skin begins to feel taxed.
No, for people with breakouts or oily skin — the friction may excite your oil glands causing the production of yet more sebum. As far as those with active breakouts, you may be moving that infection around your face to new sites.
Lastly, make sure that the “scrub” material is not sharp, i.e. made from fruit pits, or you can cause micro tears in your skin, thereby making the transfer of pimples easier. Look for words like “beads” or substances like oats, corn meal, etc., which are create friction but are relatively soft.
