Like the rest of your body, the skin on your face sheds dead cells. Too much buildup of these dead skin cells can result in pesky skin conditions. For one thing, they can clog pores and incite acne to flare up; for another, they can cause your complexion to look dull. Exfoliation does away with these dead skin cells, keeping your skin healthy and clean. It also doesn’t have to be completed just with sugar scrubs: There are plenty face masks and body lotions housed with ingredients that can do the job just as well.
There are two types of exfoliation: chemical and mechanical. Either has various methods which, if done too often, can severely damage skin. Take, for example, chemical peels: This process completely removes the top surface of your skin for a more youthful look and should only be done sparingly, due to the harsh nature of the procedure.
Casual exfoliation could also be detrimental. Facialist Joanna Vargas tells Glamour how constant scrubbing can actually strip your skin of its necessary, natural oils. This could lead to acne or redness due to irritation (not to mention dry, itchy skin). Know your skin type, and exfoliate accordingly.
