Abstract

Objectives: Dissolving microneedle patches have been extensively studied in the field of cosmetics comparison with topical cosmetics focusing on the delivery of active ingredients. Nevertheless, the skin improvement effect of hyaluronic acid, which is mainly used as a backbone material for dissolving microneedle, was not analyzed. In this study, adenosine encapsulated high and low molecular weight hyaluronic acid dissolving microneedle patch (Ad-HMN and Ad-LMN) were evaluated with respect to skin wrinkling, dermal density, elasticity, and safety in a clinical test on the crow’s feet area. Methods: Clinical efficacy and safety tests were performed for 12 weeks on twenty three female subjects with wrinkles around their eyes. The Ad-HMN and Ad-LMN patch were applied once every 3 days, in the evening, for 8 weeks to the designated crow’s feet area. Skin wrinkling, dermal density, and elasticity were measured by using PRIMOS® premium, Dermascan®C, Cutometer® MPA580, and Corneometer® CM 825, respectively. Results: Both Ad-HMN and Ad-LMN groups showed statistically significant efficacy for almost all parameters. The Ad-HMN patch had better effect on the mean depth of biggest wrinkles, maximum depth of biggest wrinkles, dermal density, and skin elasticity than the Ad-LMN patch. No adverse effects were observed in either group during the test period. Conclusion: In the clinical efficacy test of four skin-improvement parameters, the Ad-HMN patch showed the better effect than the Ad-LMN patch with the similar adenosine dose.
