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
