Background:
Microdermabrasion has become a popular method for superficial resurfacing of the epidermis. Despite the popularity of this technique, few studies have examined changes in the levels of lipids (especially ceramide) in the stratum corneum following microdermabrasion.
Objective:
To assess and analyze changes in the ceramide level in the stratum corneum during the course of serial aluminum oxide microdermabrasion.
Methods:
Eleven healthy volunteers were enrolled in this study. Each participant underwent microdermabrasion once a week for 5 weeks. Following each procedure, the ceramide level in the resulting epidermal scales was measured.
Results:
A statistically significant increase in the ceramide level in the stratum corneum was observed following the first and second microdermabrasion sessions. After the third and fourth sessions, the ceramide level returned to baseline.
Conclusion:
The results suggest that microdermabrasion alters the epidermal ceramide level. These findings provide the first evidence of alterations in the lipid barrier following microdermabrasion.

Cells of the Epidermis
The cells in all these layers except the stratum basale are called keratinocytes, a type of cell that manufactures and stores the protein keratin. The keratinocytes in the stratum corneum are dead and regularly slough away, being replaced by cells from...

Stratum Basale
Stratum basale, also known as the stratum germinativum, is the deepest layer of the epidermis. It is composed of a single layer of actively dividing cells called basal cells or basal keratinocytes. These cells constantly undergo cell division to replenish the upper layers of the epidermis. Additionally, melanocytes, which...
