The science
of light.

LED therapy has been studied clinically for over 40 years. Here is how it works — precisely.

What is
photobiomodulation?

Photobiomodulation — or PBM — is the clinical application of specific wavelengths of light to biological tissue to stimulate cellular responses. It has been studied in hospital settings for over 40 years: first for wound healing and pain management, more recently for skin rejuvenation and repair.

When light at precise wavelengths reaches the mitochondria in your skin cells, it's absorbed by an enzyme called cytochrome c oxidase. This triggers increased ATP production, reduced oxidative stress, improved cellular signalling, and accelerated repair. Your cells, in short, work better.

This is not a wellness trend. It is a well-characterised biological mechanism with a substantial peer-reviewed evidence base.

How the
RAE mask
applies it.

The RAE mask uses 122 LED beads — 488 chips in total — emitting at four distinct wavelengths in a 1:1:1:1 ratio. The mask delivers consistent, calibrated photonic energy across the full face in a single ten-minute session.

Six treatment modes combine these wavelengths in clinically-informed configurations, each targeting a different skin concern and depth of tissue. Three brightness levels — 50%, 75%, and 100% — allow you to calibrate treatment intensity to your skin's tolerance.

The device is CE and RoHS certified. The specifications are verifiable. We publish them because we expect you to look.

415

Anti-Acne

Targets and destroys Propionibacterium acnes bacteria beneath the skin surface. Reduces oil production and the inflammatory response that causes breakouts.

590

Rejuvenation

Stimulates collagen and elastin. Improves skin tone and lymphatic drainage. Particularly effective for sensitive and rosacea-prone skin.

660
nm · Red
Repair & Anti-Aging

The most extensively researched wavelength in photobiomodulation. Penetrates the dermis to stimulate fibroblast activity, collagen synthesis, and surface repair.

850
nm · Near-Infrared
Deep Repair

Invisible to the eye. Penetrates past the dermis into subcutaneous tissue. Reduces deep inflammation, improves circulation, and increases skin hydration at a structural level.

Six modes.

Mode Wavelengths Target Mechanism
M1 — Repair 660nm Redness, texture, sensitivity Reduces surface inflammation. Stimulates red blood cell activity. Supports recovery of damaged or reactive skin.
M2 — Rejuvenation 590 + 660nm Dullness, firmness, tone Stimulates collagen and elastin production. Improves microcirculation. Reduces the appearance of fine lines.
M3 — Anti-Aging 660 + 850nm Fine lines, hydration, firmness Deep tissue repair. Improved blood flow. Increased hyaluronic acid retention and skin moisture.
M4 — Morning 590 + 660 + 850nm Daily maintenance Full daytime treatment. Reduces overnight puffiness. Prepares skin for enhanced absorption of morning actives.
M5 — Anti-Acne 415nm Acne, congestion, oiliness Eliminates acne-causing bacteria. Reduces active inflammation and the risk of post-inflammatory hyperpigmentation.
M6 — Bedtime 415 + 590 + 660 + 850nm Overnight recovery All four wavelengths simultaneously. The most comprehensive treatment mode. Designed for nightly use.

Red Light & Collagen

Multiple randomised controlled trials have demonstrated that red light at 630–660nm significantly increases collagen density in the dermis after 8–12 weeks of consistent use, with measurable reductions in fine line depth and improvements in skin roughness.

NIR & Cellular Energy

Near-infrared at 850nm stimulates cytochrome c oxidase in the mitochondrial electron transport chain, increasing cellular ATP production. This accelerates repair processes across a broader tissue volume than visible red light alone.

Blue Light & Acne

Blue light at 415nm targets and destroys Propionibacterium acnes through photoactivation of bacterial porphyrins. Studies show a 76% reduction in acne lesions after four weeks of twice-weekly treatment at this wavelength.

Combination Therapy

Multiple-wavelength protocols consistently produce superior outcomes compared to single-wavelength use — because red and NIR light act on the same cellular receptors across different tissue depths, producing additive rather than redundant effects.
