Efficacy and Safety of Jmoon Transdermal Collagen Light Beauty Device for Facial Rejuvenation: A 12‐Week Exploratory Clinical Study

Background Facial photoaging affects the health and quality of life of middle‐aged and elderly individuals. While energy‐based aesthetic technologies help delay aging, clinical evidence for home‐use devices remains limited. Objective To evaluate the clinical efficacy and safety of the Jmoon Transdermal Collagen Light Beauty Device for facial rejuvenation over a 12‐week period. Methods Thirty‐six healthy female volunteers with mild‐to‐moderate facial aging were recruited. The device’s effects on facial rejuvenation were assessed using VISIA imaging, PRIMOS‐CR 3D image analysis, Wood’s lamp, multifunctional skin testing, and skin ultrasound. Results Thirty‐four participants completed the study. After 12 weeks of continuous device use, significant improvements were observed in skin hydration (33.7% increase), firmness (21.7% increase), elasticity (22.0% increase), skin tone (39.9% increase), and brightness (8.0% increase) (all p < 0.0001). Sebum (49.6% reduction), melanin (22.0% reduction), and erythema (17.0% reduction) levels also decreased significantly (all p < 0.0001). PRIMOS‐CR 3D imaging showed significant reductions in wrinkle area, length, volume, and number (all p < 0.05). Skin ultrasound revealed a significant increase in dermal thickness ( p < 0.0001). The overall average pain score was 1.9 ± 1.7 based on a 0–10 Visual Analog Scale, with no severe adverse effects such as erythema, blisters, or pigmentation. Satisfaction scores indicated that the satisfaction rate reached 94.1%. Conclusion The Jmoon Transdermal Collagen Light Beauty Device significantly improved skin hydration, oil control, whitening, firmness, elasticity, and dermal thickness, while reducing erythema and wrinkles. It demonstrated a favorable safety profile and high user satisfaction in this exploratory study. Trial Registration: Chinese Registry of Clinical Trials: ChiCTR2400090845
