We analyzed the expression levels of growth factors [fibroblast growth factor 2 (FGF2) and epidermal growth factor (EGF)] and keratin subtypes (K10) in both the b-MES and control groups at different time points after wounding. The b-MES group showed a significantly accelerated healing process of the epithelial tissue, resulting in more consistent healing as compared to the control group. A molecular biological analysis showed that the FGF2 mRNA expression level on Day 2 after wounding was significantly higher in the b-MES group, whereas the EGF mRNA expression level on Days 1, 2, and 4 after wounding was significantly lower in the b-MES group. Additionally, the K10 mRNA expression level on Days 1 and 2 after wounding was significantly higher in the b-MES group. Our study findings suggest that b-MES facilitates wound healing by regulating the growth factors. However, the precise mechanisms underlying these effects remain to be fully elucidated. Further research is needed to fully understand the therapeutic potential of b-MES and its applications in clinical setting. Clinically, m-MES requires shunting due to residual electrical charge at the application site. However, b-MES alternates polarity, leaving no charge at the site of application.

The findings obtained indicate that the following methods can be used to lessen retinoid-induced irritation in topical formulations: developing drug delivery systems in the formulation, such as encapsulating retinoids, transforming retinoids into nanoparticles, forming complexes (e.g., with cyclodextrin), and binding retinoids with carriers (e.g., polymers, NLC, SLN), adding ingredients with anti-irritation activity, skin barrier improvement, and increased skin hydration to retinoid formulations (e.g., combinations of glucosamine, trehalose, ectoine, sucralfate, omega-9, and 4-t-butylcyclohexanol, addition of ethanolic bark extract of <i>Alstonia scholaris</i> R.
