The encouraging part is that simple, regular care can make a measurable difference. In a 2025 randomized controlled trial published in the Journal of Cosmetic Dermatology, participants did just 10 minutes of facial massage, five times a week, for eight weeks. Both gua sha and facial roller massage improved facial contour measurements. The roller group improved skin elasticity by 8.6% (gross elasticity), and the gua sha group showed significantly relaxed facial muscle tone.[5]
Light is another area with real research behind it. In a 2014 controlled trial of 136 volunteers, people who received red and near-infrared light treatments twice a week for 30 sessions showed significantly improved skin complexion, smoother skin texture, and higher collagen density measured by ultrasound, compared with an untreated control group.[6]
Neither study tested Dermelle products. What they show is the principle we built around: gentle care, done consistently, at home, counts.
