Research suggests that red and near-infrared light (630-850nm) may help reduce inflammation, improve skin barrier function, and alleviate symptoms of chronic skin conditions like psoriasis, eczema, and rosacea. RLT has been studied for its ability to calm immune responses in the skin, enhance cell repair, and promote overall skin health.
Key Findings from Multiple Studies:
- A 2016 study found that red light therapy at 633nm significantly reduced psoriasis symptoms, improving skin appearance and reducing scaling.
- A 2018 clinical trial showed that near-infrared light (830nm) helped alleviate eczema symptoms by reducing skin inflammation and improving hydration levels.
- A 2021 review suggested that red light therapy can reduce redness and irritation in rosacea by strengthening blood vessel function and reducing oxidative stress.
- Research indicates that RLT enhances the skin’s ability to retain moisture, which is particularly beneficial for eczema sufferers.
Implications:
These findings suggest that red light therapy between 630-850nm may be beneficial for individuals with chronic inflammatory skin conditions such as psoriasis, eczema, and rosacea. Regular use may help reduce redness, irritation, and flare-ups while supporting overall skin health.
