Studysummary This study found that combining red light therapy with oral beta-carotene significantly improved photoaging treatment outcomes compared to red light therapy alone, with Group A showing a 56.12% reduction in photoaging scores over 12 weeks versus 44.78% in Group B. Our plain-language summary of this paper — not a Tressless recommendation.
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.
