The Hard Science of Photobiomodulation: Why Joules, Not Minutes
The Architecture of Light
A masterclass in clinical dosing and cellular harmony.
At Lumnae, we believe that beauty is a science of precision. The skin does not respond to mere light — it responds to energy. Years of engineering have gone into perfecting the delicate balance between physics and biology, to ensure that every second spent under a Lumnae mask is an investment in your skin's future.
The biological formula
This equation is the foundation of our engineering. Irradiance is the power that drives photons through the skin barrier, while Joules represent the total energy your cells receive to trigger repair. Without this calculation, light therapy is merely a glow — with it, it becomes a calibrated treatment.
Every mode in the Lumnae mask is a bespoke mathematical response to a specific skin need. Using Intensity Level 3 (45 mW/cm²), the mask achieves clinically relevant doses within the standard 10-minute session — no need to extend treatment time to compensate for insufficient power.
Our 6 modes, by the numbers
Six distinct modes, each a calibrated mathematical response to a specific skin need.
A sanctuary for compromised skin. Provides the exact energy required to accelerate wound healing and soothe post-procedure inflammation.
A sophisticated blend, mathematically optimised to brighten the complexion and revitalise the skin's natural glow.
The pinnacle of anti-aging. Combining Red and Near-Infrared reaches the deeper dermis to stimulate fibroblasts, filling fine lines from the inside out.
The most potent protocol in the device. Delivers a substantial energy surge to prepare and protect skin for the day ahead.
Precision at 415nm. This dose is specifically calculated to neutralise P. acnes bacteria at the source without stressing surrounding healthy tissue.
A three-phase restorative journey: 3 minutes of Yellow to calm, 5 minutes of Red+NIR to regenerate, 2 minutes of Blue to purify. A complete overnight restoration in a single ritual.
A 10-minute session at low irradiance can deliver less total energy than a 5-minute session at higher irradiance. Session duration alone does not indicate treatment strength — the energy dose (J/cm²) is what determines whether a therapeutic threshold has actually been reached. This is why every Lumnae mode publishes both numbers, not just the timer.

How many Joules does each Lumnae mode deliver?
Why does Joules matter more than minutes?
What is intensity Level 3 and why does it matter?
"We do not guess. We calculate. So your skin can simply glow."
- Irradiance × Time = Energy. This single equation determines whether any LED session crosses the threshold from "a nice glow" to a genuine therapeutic dose.
- Every Lumnae mode is calibrated to deliver a specific, published energy dose — from 13.2 J/cm² (M1) to 27 J/cm² (M4) — within a 10-minute session.
- Minutes alone tell you nothing about treatment strength. Always check the Joules.
