Recently, several minimally invasive gynecological, ENT and esthetic procedures have been introduced that are based on delivering “smooth” sequences of Er:YAG laser pulses to cutaneous or mucosal tissue at moderate cumulative fluences that are not only below the ablation threshold but typically also do not require local anesthesia. To explain the observed clinical results using “smooth-resurfacing,” it has been suggested that in addition to the direct heat injury to deeper-lying connective tissues, there is an additional mechanism based on indirect triggering of tissue regeneration through short-exposure, intense heat shocking of epithelia. The goal of this study is to improve understanding of the complex dynamics of the exposure of tissues to a series of short Er:YAG laser pulses, during which the thermal exposure times transition from extremely short to long durations.
