About

The purpose of this research project is to investigate the treatment design, therapeutic effects and safety of the 1927 nm laser for the rejuvenation of the skin around the eyes.

Full description

The chromophore of the 1927 nm diode laser is mainly water, which can be used for skin rejuvenation. This study intends to use the Solta CLEAR+BRILLIANT Laser System, featuring a 1927 nm diode laser with 5 mJ energy, a treatment spot of 140 μm, a treatment depth of 170 μm, and a treatment coverage of approximately 5% per energy level after four rounds of treatment using the patented Intelligent Optical Tracking® System (IOTs). The purpose of this research project is to investigate the treatment design, therapeutic effects and safety of the 1927 nm laser for the rejuvenation of the skin around the eyes. This is an open-label, single-center clinical trial. Participants will be randomized into treatment groups, including Group A (treatment interval of 2 weeks) or Group B (treatment interval of 4 weeks).
