Fig. 5. Histological analysis of photoaged ex vivo human skin after fractional microneedle radiofrequency (FMRF) and application of an antioxidant formulation. (A, B) A single pulse-type FMRF treatment induced neocollagenesis on the photoaged skin (Masson’s trichrome, ×100). (C) Subsequent treatment with the antioxidant formulation induced a further increase in collagen deposition in the FMRF-treated skin (Masson’s trichrome, ×100). FMRF, fractional microneedle radiofrequency.
