Microdermabrasion has a wide range of potential applications and an equally varied host of cosmetic benefits.   The most common reason people use microdermabrasion is to reduce the appearance of fine lines and wrinkles caused by natural aging, stress, and sun damage. Hyperpigmentation can be treated with microdermabrasion. Melasma, or any type of aging spots or darker patches on your skin, can fall under this category. If you have a current breakout of acne or irritated skin, including blackheads, microdermabrasion isn't recommended. In cases where you get blackheads frequently, the treatment may help shrink your pores. Some dermatologists recommend microdermabrasion to improve your skin's condition and reduce pores. The effectiveness of microdermabrasion for treating stretch marks is at least as good as that of other popular topical treatments, such as tretinoin cream. Microdermabrasion enhances your skin's ability to heal by stimulating cell turnover. Perhaps that's why the treatment works especially well at the onset of stretch marks.
