Abstract

The demand for skin rejuvenation procedures has progressively increased in the past decade. Additionally, clinical trials have shown that current therapies might cause downtime and side effects in patients including prolonged erythema, scarring, and dyspigmentation. The goal of this study was to explore the effect of partial irreversible electroporation (pIRE) with pulsed electric fields in aged skin rejuvenation as a novel, non-invasive skin resurfacing technique. In this study, we used an experimental model of aged rats. We showed that treatment with pIRE promoted keratinocyte proliferation and blood flow in aged rat skin. We also found significant evidence indicating that pIRE reformed the dermal extracellular matrix (ECM). Both the collagen protein and fibre density in aged skin increased after pIRE administration. Furthermore, using an image-processing algorithm, we found that the collagen fibre orientation in the histological sections did not change, indicating a lack of scar formation in the treated areas. The results showed that pIRE approach could effectively stimulate keratinocyte proliferation, ECM synthesis, and angiogenesis in an aged rat model.
