What Is Microdermabrasion For?

Microdermabrasion is an abrasive skin-smoothing technique. Depending on the laws of individual states, microdermabrasion is performed by dermatologists, plastic surgeons, physician-supervised practitioners such as nurses, and licensed esthetitians. Microdermabrasion reduces signs of sun damage and aging, helps to clear up acne and repair superficial acne scars on the face and other areas of the body. The results are similar to those of a mild chemical peel, according to the University of Maryland Medical Center.

Method

Microdermabrasion is a mild form of dermabrasion, which is a deeper, more abrasive method of polishing and refining the skin that was used more often in the past to remove several layers of skin at one time. During microdermabrasion treatments, tiny aluminum oxide or diamond crystals pass at a high speed through a tube-shaped tool. They exfoliate, or "sand away" only the outermost layer of skin. A vacuum removes the crystals and ablated skin. An even milder form of microdermabrasion is sometimes performed by skin care specialists in spas and salons, and can be done at home, using gentle, abrasive creams to remove dead skin cells from the surface of the skin.

Time Frame

Microdermabrasion treatments generally last about 30 minutes. Several microdermabrasion treatments are usually required. Depending on individual skin type and condition, approximately six treatments, spaced seven to 10 days apart, are recommended for best results by the University of Rochester Medical Center. One treatment will smooth and refresh the skin, but is not usually enough to repair skin problems.

Effects

Microdermabrasion acts only on the outermost layer of skin, known as the stratum corneum of the epidermis. This technique smooths skin texture, evens out skin coloring and improves the overall appearance of the skin, according to a study published in the June 2001 edition of Dermatologic Surgery. By removing the topmost layer of skin, healthier skin below is exposed and lower layers of skin are stimulated to create fresh new cells. Topical moisturizing and healing products are more effective because they can reach deeper below the skin's surface.

Warning

Because microdermabrasion is a relatively new procedure that can be performed by a variety of professionals with varying levels of education and experience, and enforcement of the regulations governing this procedure vary from state to state, it is important for consumers to know the training, license and skill level of an individual practitioner.

Theories/Speculation

Because microdermabrasion acts only on the very top layer of skin cells, it is generally considered a superficial skin resurfacing technique. A University of Michigan Medical School study published in a 2006 edition of the Journal of the American Academy of Dermatology suggests, however, that microdermabrasion may stimulate deeper layers of skin to continue to send healthy new cells to the surface and remodel the skin after treatment is completed.
