It is theorized that the repeti- tive intraepidermal damage produces ﬁbroblast proliferation and collagen production in the treated areas, resulting in an improvement of the appearance of wrinkles [36 ]. These are interspersed with a cleaning of the skin surface, and having as end point the onset of erythema. Several clinical studies have shown histologic changes with an increased vascularity, increased thickness of epider- mis and dermis associated with a moderate subjective improvement reported by the patient [37, 38 ].
