Microdermabrasion: Reappraisal and brief review of literature.
BACKGROUND: Microdermabrasion (MDA) is a recently introduced noninvasive, nonsurgical, office-based esthetic procedure for revitalizing and rejuvenating the skin. It is a closed-loop vacuum-assisted abrasive procedure, which uses the physical action of inert crystals to exfoliate the skin. OBJECTIVE: The aim was to evaluate the procedure of MDA in postacne scarring, melasma, and facial rejuvenation, and review the relevant literature. METHODS: Ten patients each of postacne scarring, melasma, and facial rejuvenation were treated by a series of weekly MDA sittings alone or in conjunction with a topical retinoid. The results were assessed by patient questionnaire and an objective assessment by two independent observers. The literature was reviewed to find indications and efficacy of MDA. RESULTS: All the patients of postacne scarring, melasma, and facial rejuvenation reported a mild but definite improvement, which increased when MDA was performed in conjunction with a topical retinoid. Most of the literature based on subjective and patient-dependent assessment parameters points toward a marginal improvement in the skin appearance following repeated procedures. CONCLUSION: Reappraisal of this potentially useful procedure points toward a need for well-designed clinical trials and studies with a long follow-up based on objective assessment parameters.
