Often called “microderm” for short, microdermabrasion is a procedure to help exfoliate or temporarily remove a few of the top layers of the skin called the stratum corneum. Much like brushing one's teeth, microdermabrasion helps to gently remove skin “plaque” and skin debris.[citation needed] Since human skin typically regenerates at approximately 30-day intervals, skin improvement with microdermabrasion is temporary and needs to be repeated at average intervals of two - four weeks for continued improvement. Multiple treatments in combination with sunscreen, sun avoidance, and other skin care creams yield best results.
