Yes, red light therapy (RLT) is legit and has been studied for various medical and cosmetic applications. It uses low-level wavelengths of red or near-infrared light to penetrate the skin and promote cellular repair, reduce inflammation, and stimulate collagen production.
Red light therapy (RLT) is generally considered safe, but its use during pregnancy remains controversial due to limited research on its effects on fetal development. For more information, you can consult your doctor.
Red light therapy promotes facial collagen production. Red light (630-660nm) and near-infrared light (810-850nm) penetrate deep into the skin and stimulate the mitochondria to increase ATP (energy) production, which activates fibroblasts and promotes collagen and elastin synthesis. This helps reduce wrinkles, improve skin elasticity, improve skin tone and texture, and accelerate skin repair. Consistent use of a high-quality red light device, 3-5 times per week, usually results are visible in 8-12 weeks.
