Microdermabrasion is a mostly noninvasive procedure that removes the uppermost layer of the skin. The process is performed using a small handheld machine that removes the dead cells at the top layer of the skin and gives the patient younger looking skin that is also healthier. Microdermabrasion can help a patient reduce the visibility of sun spots, acne scars and fine lines. One of the reasons for its popularity is that it is a painless procedure. Just like any other treatment performed on a person, there are pros and cons to having a microdermabrasion procedure.
