Changes of the Skin Barrier and Bacterial Colonization After Hair Removal by Clipper and Razor

The study compared the effects of hair removal using a clipping device versus a disposable razor on the skin barrier and bacterial colonization in 12 healthy volunteers. Results indicated that both methods reduced bacterial colony-forming units, but clipping led to a greater reduction and a continuous decrease over time. In contrast, the razor-treated group experienced an increase in bacterial colonization from baseline to 24 hours post-removal. Additionally, the use of a razor resulted in more microlesions and a significant increase in transepidermal water loss, indicating skin barrier disruption. Clipping did not significantly affect transepidermal water loss. The study concluded that clipping is less disruptive to the skin barrier than shaving with a razor, which could be beneficial in preventing surgical site infections and improving postoperative wound management.
