What does laser infrared therapy do for the skin?

Background:Previous studies have documented the effectiveness of visible or near-infrared light for skin rejuvenation. This study explores the use of LASER photorejuvenation, which combines these wavelengths to enhance their unique cellular stimulation effects.
Objective:To evaluate the effectiveness and local tolerability of combined light therapy for facial skin rejuvenation.
Methods: Thirty-one participants with facial wrinkles underwent nine treatments using the COZING-T03C LASER system. This system used wavelengths of 650 nm and 808 nm with fluences of 126 J/cm² and 66 J/cm², respectively. Skin surface improvements were assessed at weeks 9 and 12 using profilometry on periorbital casts. Additional outcomes included clinical photography assessments and patient satisfaction scores.
Results: Significant improvements were observed in key profilometry metrics Sq, Sa, Sp, and St at the 12-week follow-up. By week 12, 52% of participants exhibited a 25%-50% improvement in photoaging scores. Additionally, 81% of subjects reported significant improvement in periorbital wrinkles at the end of the follow-up period.
Conclusion: The COZING combination of red and near-infrared laser therapy is an effective and well-tolerated method for photorejuvenation. Further research is needed to optimize treatment parameters.
