Red Light Therapy

Red Light Therapy for Aesthetics: Detailed Overview and Supporting Studies

Red light therapy (RLT) leverages specific wavelengths of red and near-infrared light to stimulate cellular processes, enhancing skin health and appearance. Here’s an in-depth look at its aesthetic applications and scientific backing.

Mechanism of Action

Cellular Stimulation: Red light therapy works by penetrating the skin and being absorbed by the mitochondria, the energy powerhouses of cells. The light energy boosts mitochondrial activity, increasing the production of adenosine triphosphate (ATP). Enhanced ATP production leads to improved cellular function, promoting regeneration and repair.

Key Wavelengths: The most effective wavelengths for aesthetic purposes are:

Red Light (630-660 nm): Primarily affects the skin’s surface and upper dermis.

Near-Infrared Light (810-850 nm): Penetrates deeper into the skin, reaching muscles and joints.
