Collagen Use in Periorbital Rejuvenation for Chinese Patients: The Restoration Injection for Optimal Rejuvenation Technique

Modern periorbital rejuvenation treatments involve a comparison of various injectable materials to optimize therapeutic outcomes. This article highlights the advantages of collagen in periorbital rejuvenation and introduces the restoration injection for optimal rejuvenation (RIO) technique as a precise and safe injection method. Due to the complex anatomical and physiological characteristics of the periorbital area, conventional injectable materials may lead to adverse reactions or suboptimal results. Collagen, however, offers excellent adhesion and minimal migration, and effectively improves both pigmented and structural dark circles. To ensure long-term results and minimize complications, the RIO technique, developed based on the authors' years of injection experience, optimizes collagen application. This low-cost technique is suitable for personalized customization, is safe and effective, and provides patients with a reliable periorbital rejuvenation solution.
