Microdermabrasion: molecular mechanisms unraveled, part 2

Microdermabrasion (MDA) remains a common in-office procedure for many dermatologic practices. The procedure offers minimal downtime with a low incidence of side effects, making it a relatively desirable option for skin rejuvenation. Investigators have identified many of the molecular mechanisms behind this technology in an attempt to optimize clinical results. In particular, activation of the wound healing response plays a key role in the remodeling of post-MDA treated skin, although this response varies based on the type of MDA employed. In addition, advances in MDA technology offer new and promising ways to enhance transcutaneous penetration of active ingredients to improve clinical outcomes. Our review addresses innovative applications of MDA in the last 10 years of research.
