Clinical and Dermoscopic Evaluation of Red Light Emitting Diodes With Beta-Carotene Versus Red Light Emitting Diodes Alone in Treatment of Photoaging

The study evaluated the effectiveness of combining red light-emitting diode (LED) therapy with oral beta-carotene versus red LED therapy alone in treating photo-damaged skin. Subjects were divided into two groups: Group A received red light therapy and oral beta-carotene, while Group B received only red light therapy. Results showed that Group A experienced a 56.12% reduction in the Dermoscopic Photoaging Scale (DPAS) at 12 weeks, compared to a 44.78% reduction in Group B. The difference in DPAS reduction between the groups was statistically significant (P = 0.001), indicating that the combination of red LED therapy with oral beta-carotene was more effective in treating photoaging than red LED therapy alone.
