Red light therapy masks have become a popular choice in skincare and beauty, but do they actually improve skin? The answer is yes—but understanding the science behind them is key.
Red light therapy, also known as Low-Level Light Therapy (LLLT), uses specific wavelengths of red light (typically between 600 to 650 nanometers) to penetrate the skin layers and stimulate cellular energy metabolism. Specifically, red light enhances mitochondrial activity, boosting ATP (adenosine triphosphate) production, which accelerates skin cell repair and regeneration.
Studies show that red light therapy can reduce inflammation, improve blood circulation, increase collagen synthesis, and enhance skin smoothness and elasticity. These effects help diminish wrinkles, fade dark spots, and even alleviate acne.
However, achieving optimal results requires consistent use over time, proper application, and complementary skincare routines. While red light therapy offers noticeable benefits, severe skin concerns should still be addressed by a dermatologist or medical professional.
