Research shows that exposure to red and near-infrared light can help improve skin health by boosting collagen production, increasing skin hydration, and reducing the appearance of fine lines and wrinkles. Studies conducted on both animals and humans have demonstrated that wavelengths between 630-850nm penetrate the skin, stimulating cells to repair and rejuvenate.
Key Findings from Multiple Studies:
- A 2014 study found that participants using red light at 633nm and 830nm experienced a 29% increase in collagen density, leading to smoother and firmer skin.
- A 2013 review confirmed that regular RLT treatments improved skin tone, reduced wrinkles, and enhanced elasticity without negative side effects.
- A 2018 trial reported that individuals receiving red light therapy twice a week for 12 weeks saw significant improvement in skin hydration and overall complexion.
- Studies indicate that RLT increases blood circulation to the skin, delivering more oxygen and nutrients for faster healing and a youthful glow.
