How Does Red Light Therapy Work?
Red light penetrates deeper than topical treatments, energising mitochondria in skin cells through a process called photobiomodulation. When red light wavelengths reach the mitochondria—often called the powerhouse of the cell—they stimulate the production of adenosine triphosphate (ATP), the energy currency that fuels all cellular functions. This increased energy availability allows skin cells to work more efficiently, accelerating natural repair processes and enhancing overall skin health.
This boost in cellular energy production enhances repair mechanisms, improves blood circulation bringing oxygen and nutrients to skin tissue, and increases elasticity through enhanced collagen and elastin synthesis. The improved circulation also aids in removing cellular waste products, creating a healthier environment for skin renewal. Clinical dermatology has used similar wavelengths for years in professional settings for anti-ageing treatments, wound healing, and skin rejuvenation protocols.
However, it's important to understand that home devices deliver lower intensity light than professional treatments, which affects both the speed and magnitude of results. Professional devices may use 100-200 milliwatts per square centimetre, whilst home devices typically range from 20-50 milliwatts. This means home users need longer treatment times and more consistent use over extended periods to achieve comparable results to clinical treatments
