Experts believe that for skin care with hyperpigmentation, you can also use a scrub with glycolic acid, which can be bought in a pharmacy. The frequency of use of such a scrub, you should discuss with a cosmetologist. Theoretically, if the goal is only to remove the dead skin from the face, the peeling procedure should be carried out once every few days. If you are struggling with hyperpigmentation, then such a procedure should be carried out at least twice a week.
