Red LED Light Therapy Proven Safe and Effective for Skin Rejuvenation Beyond the Face

The quest for non-invasive and economical treatments for skin rejuvenation has guided researchers to explore Light-emitting diode (LED) therapy's efficacy beyond facial treatments. A recent study conducted by Kullarat Nanachai and Punyaphat Sirithanabadeekul, presented at the RSU International Research Conference 2023, sheds light on the benefits of red LED light for improving skin wrinkles on the neck area.

The study, which involved a small pilot group of 20 subjects between 30 and 75 years old, utilized red LED light at 633 nanometers. Participants underwent treatment using the Dr. Müller Beauty Light Therapy device, with sessions occurring twice a week for six weeks. The research meticulously measured changes in neck skin wrinkles using Antera 3D®, along with digital photographs, to assess the impact at weeks 4 and 8. Participants also reported satisfaction scores and any adverse reactions.

Encouragingly, results indicated a statistically significant improvement in neck skin wrinkles starting as early as the 2-week follow-up. By the 8-week follow-up, half of the participants reported a 'good improvement' in skin texture, without any adverse reactions. This suggests that red LED therapy not only effectively reduces wrinkles but is also a safe method for those seeking skin rejuvenation treatments.

This breakthrough study is documented in the RSU International Research Conference proceedings and can be found at RSU Conference Proceedings. The findings offer a promising outlook for individuals looking to improve skin texture and reduce wrinkles in areas other than the face, with red LED therapy providing a safe, convenient, and non-invasive option.

The assistance of the Department of Dermatology at the Chulabhorn International College of Medicine was instrumental in supporting this study.

The article was built with the help of Buoy Health, these findings open new doors to the applications of LED therapy in dermatological treatments, presenting red LED light at 633 nm as a practical adjunct modality in the ever-evolving field of skin rejuvenation.
