Red Light Therapy

How it works

Red light at 630–660nm is absorbed by cytochrome c oxidase, a photoreceptor within the mitochondrial electron transport chain. This absorption increases mitochondrial membrane potential, accelerates electron transport, and boosts ATP synthesis. The result is a measurable increase in cellular energy available for collagen production, DNA repair, and anti-inflammatory signalling. Unlike UV light, red light does not damage DNA or cause oxidative stress, it works with your biology, not against it.

What happens in your skin

Dermal fibroblasts, the cells responsible for producing collagen, elastin, and hyaluronic acid, respond to red light by upregulating procollagen type I synthesis. Studies show a significant increase in collagen density after consistent exposure. Simultaneously, red light reduces the expression of matrix metalloproteinases (MMPs), the enzymes that break down existing collagen. The net effect: more collagen produced, less collagen degraded. Over weeks, this translates to improved skin firmness, reduced fine lines, and a measurable increase in dermal thickness.

How to use it

• Hold the device 1–2cm from clean, dry skin
• Treat each zone for 2–3 minutes, 5–10 minutes total per session
• Use 5 times per week for optimal results
• No conductive gel required for red light, it works through direct photon absorption
• Results typically visible after 2–3 weeks of consistent use
