MICRODERMABRASION
MICRODERMABRASION
Microdermabrasion removes the stratum corneum, resulting in the stimulation of dermal fibroblasts and epidermal renewal.16,17 Most microdermabrasion units consist of closed-loop negative pressure systems that pass aluminum oxide crystals into the skin; sodium chloride crystals and positive pressure are also used.18
This method has limited scientific data to support its efficacy. Although microdermabrasion may assist light penetration when used in conjunction with lightbased therapies, one study reported that microdermabrasion used in conjunction with a 1,450-nm diode laser did not enhance the effect of laser for treatment of inflammatory acne, although the absorption of topical medications was increased when used with PDT.19,20
