Unfortunately microdermabrasion does not help with active acne (red pimples) or with acne scars. Microdermabrasion is a good option when one has only comedones (white heads and blackheads). Nevertheless, if one has in addition to the comedones also many red inflammatory pimples the microdermabrasion will irritate the skin and make acne worse.
