Photobiomodulation
Light at the right wavelength changes how your skin cells behave. That’s photobiomodulation. Here’s the science behind how it works, what the research shows, and why this mask is designed to deliver accuracy and efficacy in 10 minutes every day.
The science
PBM, also known as low-level laser therapy, uses gentle red or near-infrared light, from 600 to 1100 nanometres, to stimulate cellular repair and reduce inflammation. Unlike surgical or cosmetic lasers, PBM is a non-invasive treatment that does not heat, burn or destroy tissue. It uses safe, non-ionizing light, making it one of the safest therapies available.
There's nothing mysterious about it. Light is absorbed in the skin cell, the cell makes more energy, and the cell puts that energy to work with 3 actions.
01
Your cells contain light-sensitive molecules called chromophores, and they absorb specific wavelengths. The best-known one is cytochrome c oxidase, an enzyme inside the mitochondria. It responds to red and near-infrared light, which is exactly why those wavelengths are used.
02
Absorbing that light nudges the mitochondria to produce more ATP, the molecule your cells run on. It also releases signalling molecules like nitric oxide. So the cell has more energy on hand, and a signal to use it.
03
Cells spend that energy on repair: building collagen and elastin, calming inflammation and improving local circulation. Consistency is key. Wear the mask 10 minutes a day, every day.
Photobiomodulation has decades of research behind it and thousands of peer-reviewed papers. Here are 4 results, each with the sample size, the study length and a link to the abstract.
76%
107 people with mild to moderate acne did daily 15-minute sessions of violet 415 nm and red 660 nm light for 12 weeks. Comedones improved by 58%.
Papageorgiou et al., Br J Dermatol 2000up to 36%
76 people in a randomized, split-face, sham-controlled trial used 633 nm and 830 nm light twice a week for 4 weeks. Skin elasticity improved by up to 19%.
Lee et al., J Photochem Photobiol B 200781%
31 people had 9 sessions of 633 nm and 830 nm light. By week 12, 52% showed a 25 to 50% improvement in photoaging scores.
Russell et al., J Cosmet Laser Ther 200586%
60 people in a randomized, double-blind, sham-controlled trial used a home LED mask at 630 nm and 850 nm for 16 weeks, graded by independent raters.
Park et al., Medicine 2025These are published studies of red, near-infrared and violet LED light therapy using a range of devices, doses and settings. They aren't trials of this mask, and individual results vary. A further controlled trial of 136 volunteers (Wunsch and Matuschka, 2014) measured an increase in collagen density by ultrasound. This mask is a cosmetic device, not a medical treatment.
360 light sources: 90 chips with 4 LEDs each, giving 5 wavelengths across the mask. Each one stops at a different depth and does a different job.
415 nm
The shallowest of the 5 wavelengths, working right at the surface. It's aimed at acne-causing bacteria and the inflammation that comes with them. You'll find it in the Anti-acne and Bedtime modes.
590 nm
Targets the epidermal and upper dermal skin layers to soothe irritation, reduce redness, and boost radiance. Yellow also modulates melanin production and tyrosinase activity to help lighten melasma and hyperpigmentation. Yellow is usually paired with red. It runs in Rejuvenation, Morning and Bedtime modes.
633 nm
Targets the mid dermis. This is the anti-aging wavelength. It boosts collagen and elastin production to fade fine lines and wrinkles. It refines pores and skin texture, calms inflammation and improves radiance. It runs in 5 of the 6 modes: Repairing, Rejuvenation, Anti-aging, Morning and Bedtime.
850 nm + 1072 nm
The 2 deepest of the 5 wavelengths, and almost invisible. Near-infrared is used for deep repair, circulation and hydration. It's the perfect complement to red light. It runs in Anti-aging, Morning and Bedtime modes.
Depth
The mask gives off 5 wavelengths, and each one stops at a different depth. Shallow to deep, left to right.
The shallowest. It stays in the epidermis.

Travels through the mid dermis.
Passes the dermis into the deeper tissue.
The deepest, and invisible to the eye. The chips around the eyes and the nasolabial folds carry it.
Design
The shape and fit of an LED mask can affect how much light actually reaches the tissue and how cells respond to it. The logic is simple. Most masks don't contour the face, so the light hits at an angle and reflects off the skin, and reflected light is wasted light. This mask is made of flexible medical-grade silicone that moulds to your face, so the LED chips sit close to the skin at a consistent distance across the forehead, the cheeks and the sides of the nose, reducing the amount of reflected light. More light absorbed means faster results.
Fit
Same LEDs, same light. Distance and angle decide how much of it gets into the skin.
Contoured siliconeThe LEDs sit close to the skin, at one consistent distance across the forehead, the cheeks and the sides of the nose. The light is absorbed, not reflected.
Rigid shellThere's an air gap at the brow, around the eyes and at the mouth. Light arrives at an angle, and part of it bounces off and never reaches the skin.
Founder
“I've worked with lasers and light-based devices every day for 24 years. I understand light and how it benefits skin. It's what I do. I've worked with one of the world's top LED device manufacturers to create a lightweight, comfortable mask using cutting-edge technology. The design, fit, and efficacy of this mask is beyond comparison. The best part is, it’s affordable luxury that delivers exceptional results in just 10 minutes every day.”

Standards
Guaranteed clinical quality in every device . Every single LED is tested to ensure it emits the exact light proven in research. The approvals this mask carries, for Canada, the US, the EU and the UK.
Photobiomodulation, also called low-level light therapy or red light therapy, uses low-power red, near-infrared or violet light to change how cells behave. It's non-thermal, so it doesn't heat, cut or damage tissue. Light-sensitive molecules in your cells absorb specific wavelengths, the mitochondria produce more ATP, and the cells use that energy to repair themselves, build collagen and calm inflammation.
The mask has 90 LED chips on the face, and every chip carries 4 LEDs: violet 415, yellow 590, red 633 and a near-infrared LED. That one is 1072 nm on the chips around the eyes and the nasolabial folds, where it targets lines and wrinkles, and 850 nm everywhere else. That works out to 360 individual light sources, so the light covers your face evenly instead of in a patchwork of single-colour diodes. The MSK588 has 147 chips, or 588 light sources.
Every day, for 10 minutes. Each mode runs for 10 minutes by default, and the timer turns it off for you.
The MSK360 is the mask on its own: 90 chips, 360 light sources, $450. The MSK588 adds 57 chips under the jaw, for 588 light sources, at $650. Same wavelengths, same 6 modes, same 10-minute timer.
Because it was priced that way on purpose. The LED chips and the contoured medical-grade silicone weren't the place to economize, so the retail price was. The MSK360 is $450 CAD and the MSK588 is $650. The idea is that good light should be something you own, not something you rent by the session.
No. Pregnancy, trying to conceive and breastfeeding are all reasons not to use the mask. If your situation isn't straightforward, check with your own clinician.
Yes. Before your first facial session, run it for 10 minutes on your arm. If you see redness or feel itching, stop and talk to a clinician before you go any further.
