Tissue removal scores of skin layers. Quantitative representation of removal scores of stratum corneum and viable epidermis for an untreated control site and sites exposed to different numbers of passes of mobile-mode microdermabrasion at 50 kPa vacuum pressure, displayed as the mean values (a) and the frequency distribution for a total of 180 scores for each site (b). Numbers above the bars represent means (a) and percent frequency (b). Error bars correspond to standard deviations. SC=stratum corneum, VE=viable epidermis.
