KIRA Hydrating TreatmentとJet Peelの顔の保湿効果の比較

概要

This study compared the effects and tolerability of two non-invasive facial treatment systems on skin hydration: a hydroabrasion-jet system (KIRA) and a conventional high-pressure jet system (JET PEEL). Twenty-three women aged 30-65 years underwent three treatment sessions in an intraindividual split-face design, with KIRA applied to the left side of the face and JET PEEL to the right side. Skin hydration was assessed by corneometry at baseline, 48 hours after the first treatment, before the second treatment, and before the third treatment; the measurement before the third treatment was the primary endpoint. Additional exploratory assessments included multispectral skin imaging, participant-reported treatment experience and preference, and a 21-day follow-up. The study evaluated differences in hydration outcomes between a protocol combining vacuum-assisted hydroabrasion with 5-bar jet infusion and a conventional high-pressure jet treatment at 6.89 bar.
