Red Light Therapy
Red light,
made personal.
A professional-grade red and near-infrared spectrum at the core — extended by a personalised wavelength layer guided by CELA™. Ten quiet minutes. One intelligent ritual.
Every CellSync device is built on three foundation wavelengths with the deepest evidence base in cosmetic light therapy: red at approximately 630nm, near-infrared at 830nm, and blue at 415nm. This is the core. The lift, the smoothness, the look of clarity — most of the visible work happens here.
The Spectrum Mask carries the same core, and extends it with a personalised spectrum layer below.
Red
Anchors radiance, the look of firmness, and a smoother, more even-looking complexion.
Near-infrared
Travels deeper than any visible wavelength. Associated with the look of refreshed, well-rested skin.
Blue
Long used in cosmetic settings to support the look of clearer, calmer-looking skin.
The Spectrum Mask Flagship
The personalisation layer.
On top of the core, the Spectrum Mask carries five further wavelengths CELA can reach for when your latest scan calls for them — yellow, green, cyan, orange and purple.
These aren’t standalone treatments. They’re a tuned palette CELA paints with, on top of the foundation, so a session in March doesn’t have to look the same as a session in October. This is what makes the flagship a flagship.
Yellow
approximately 590nm
A warm-spectrum wavelength selected for its association with skin that looks comforted and luminous.
Green
approximately 520nm
A balancing wavelength chosen for its visual quietness — for sessions where evenness of tone is the goal.
Cyan
approximately 490nm
A cooler-spectrum wavelength selected to support the look of refreshed, awake skin.
Orange
approximately 590nm + 630nm
A composite wavelength bridging yellow and red — selected for its warm, glow-supporting character.
Purple
approximately 415nm + 630nm
A composite wavelength bridging blue and red — selected to extend the spectrum’s reach across the visible range.
The Ritual
Ten minutes. Considered.
A Spectrum Mask session begins in the CellSync app. Open CELA, and she’ll have already chosen your wavelengths for the evening based on your most recent scan, the time of day, and the rhythm of your previous sessions.
When the session ends, the app records it. Your next scan tells CELA what’s changing, and the session after that is tuned accordingly.
CELA tunes your spectrum
CELA has already chosen your wavelengths, intensity and session length — informed by your latest scan.
Ten quiet minutes
Cleanse, settle in, and let the mask deliver. Eyes closed. No menus to navigate.
The next scan tells her more
The app records the session. Your next scan refines what CELA knows for the one after.
The Output
Calibrated to deliver, every session.
Each wavelength channel is calibrated to a measured output. The Spectrum Mask is built to a professional-grade specification, intended for home use, with full output documentation available to qualified partners on request.
