Abstract: There is growing interest for non-invasive and affordable procedures for skin rejuvenation in the recent years. Light-emitting diode (LED), a form of phototherapy, is one of the modalities that has been used for skin rejuvenation. Most of the studies had conducted on the facial skin, however, there are not many reports that determine the effectiveness of LED on other area on the body. The objective of this study was to evaluate the effect of red LED at 633 nanometers on the neck area. This was a pilot study conducted on 20 subjects aged 30 to 75 years’ old who were interested in skin rejuvenation. All subjects underwent red LED treatment using Dr. Müller Beauty Light Therapy device twice a week for six weeks. Primary outcome measured in the study were the changes in neck skin wrinkles using Antera 3D®. Digital photographs were taken at baseline, week 4 and week 8 follow-up. The assessment was done at baseline, week 2, 4, 6, and 8 follow-ups. Subject’s satisfaction score and adverse reactions were also recorded. All 20 subjects completed the study and attended all follow-up. The neck skin wrinkles analysis, using Antera 3D®, showed statistically significant improvement from 2-week follow-up onwards compared to baseline. Majority of the subjects (50%) scored good improvement on the neck skin at 8-week follow-up. No adverse reaction was reported. Red LED at 633 nm is safe and can be used as an adjunctive modality for skin rejuvenation
