Monopolar radiofrequency treatment for facial laxity: Histometric analysis.

Background: A monopolar radiofrequency device can be used in facial tightening. The device targets the dermis and fibrous septae, and the treatment results in immediate collagen contraction and the induction of subsequent collagen remodeling.

Aims: We aimed to evaluate the histometric change of the subjects treated with a monopolar radiofrequency device using a novel tip.
