The Nooance Aurion X252 LED mask is the smaller model in the Nooance range, with 252 dual-core LEDs, 45 mW/cm² of irradiance and a battery built into the forehead of the shell instead of a remote. I wore it for 8 weeks, 4 sessions of 10 minutes a week, 32 sessions in total. What sets it apart is that there is nothing to hold and nothing to plug in during a session, and the whole LED mask weighs less than 0.7lbs.
So here is my full review of Nooance Aurion X252: the score, what the FDA file reveals about its light output, and the exact spots on the face where the light does not land.
84/100
Emilie Approved since September 2026The shell is thin, sits tight on the face, and 45 mW/cm² from a 286 g device is real work, but 126 light points leave the crow’s feet without an LED of their own and the battery wants a charge every week.
Buy it if
- You want a cordless LED mask you can wear while doing something else, with no remote to clip on and no cable to mind.
- You want 633 and 830 nm at 45 mW/cm², an FDA file that names this exact model and a clinical study run on it, for $449.
- Your first concerns are tone, texture and radiance rather than deep wrinkles.
Skip it if
- Crow’s feet are the reason you are buying, because no LED sits directly on them here.
- You want the highest LED density on the market for full face coverage.
What I tested: the Nooance Aurion X252 LED mask
I paid for this LED mask myself. I do have a partnership with Nooance now: the code TESTEMILIE15 takes 15% off and pays me a commission. That commission doesn’t touch the score or the verdict below.
I bought the Aurion X252 on Nooance’s US shop at $449. The protocol was 4 sessions of 10 minutes a week for 8 weeks, with the eye shields in every time. Nooance recommends 5, which is what its clinical study used, while its own manual says 30 to 50 minutes a week, so 4 sits inside their range too. I could’ve gone to 5, but 4 evenings is the rhythm I kept without it feeling like a chore.
Results: 4/5
My results with the Aurion X252 from Nooance
I’ve been undergoing red light therapy since 2025 using high-quality LED masks, so I wasn’t expecting to see visible results in photos from this test. But the upside is that my skin hasn’t lost the benefits I’ve gained, whereas many of the LED masks I test actually undo those benefits when they’re of poor quality…
The one before and after I can show you comes from the Elite X600, the bigger Nooance model with the same 633 and 830 nm at 50 mW/cm², over 12 weeks. That is where I photographed a change, on tone and on the pores along my nose.
Nooance Results on Aurion X252
For the X252 itself, Nooance had the GREDECO laboratory in France run a 90-day study on this exact model: 20 women, average age 58, 5 sessions of 10 minutes a week, instruments named and statistics published.
At day 90 it reports:
- complexion uniformity improved by 83%,
- skin texture by 23%,
- dermal density by 58%,
- elasticity by 21% and radiance by 14%,
- nasolabial folds down 9% and crow’s feet down 11.5%.
Those are measured results published by Nooance, with 0 adverse events over the test period. Unfortunately, Nooance did not publish photo from that study to put next to them.
Irradiance: 4.5/5
Nooance publishes 45 mW/cm² and 27 J/cm² per 10-minute session, which is exactly what 45 mW/cm² gives over 600 seconds, so the 2 figures agree with each other. 45 is inside the 30 to 50 band I consider useful.
- Nooance Aurion X252 45
- Nooance Elite X600 50
- CurrentBody Series 2 30
- Omnilux Contour Face 30
What Nooance does not write for this model is where the 45 was measured. The Elite X600 page says in direct contact with the skin, and both LED masks come from the same file, so I’d expect the same condition.
Coverage: 3.5/5
Nooance Aurion X252: 252 LEDs or 126?
The LED mask carries 126 light points, and each one is a dual-core emitter with a 633 nm diode and an 830 nm diode inside, which are 126 red LEDs and 126 near-infrared LED for a total of 252 LEDs. So Aurion X252 has 126 unique spots on the area, and it’s the low end of what I accept for a full-face LED mask. For scale, the Nooance Elite X600 (you can read my review here) puts 300 unique light outputs.
The LEDs are positioned quite well, with the forehead, cheeks, nose, and upper lip well-lit, and the lower part of the chin somewhat lit. The underside of the chin doesn’t receive any light because the shell stops at the jawline, and the crow’s feet are the area I like the least since an entire line isn’t covered.
The area around the eyes does receive some light from the neighboring LEDs, but less than the other areas, and I would have liked to see a row of LEDs there.
What makes it work is the fit. The shell is rigid but thin, allowing the two straps to hold the LED mask against the face, and the nose groove is deep enough that no part of it presses against the bridge of the nose. As a result, each emitter is in direct contact with the skin, and the 45 mW/cm² is effectively absorbed rather than lost in an air gap.
Proof: 5/5
What the brand publishes
- Published: Wavelengths in nm, 633 and 830, stated to ±2 nm
- Published: Session dose published, 27 J/cm² in the manual, consistent with 45 mW/cm² over 10 minutes
- Published: FDA clearance number, K260150, verifiable in the database for model MJ-66DB
- Published: Clinical study run on this exact model
- Published: Study documented: 20 volunteers, 90 days, laboratory, dermatologist, instruments and statistics named
- Published: Photobiological safety: IEC 62471 exempt risk group printed in the manual, testing listed in the FDA summary
- Published: Two year warranty and documented after-sales contact
Proof: 5/5
Nooance commissioned the GREDECO laboratory to conduct the study above with protocol D118.9.25, run on the X252, supervised by a named dermatologist, with the Cutometer, the ultrasound probe, the VISIA camera and the PRIMOS wrinkle scanner listed, and the statistical tests printed under the results. That’s the instrumental level of proof.
What I miss from it is a photograph to see a clear Before&After from the Aurion X252. Else, the FDA side is clean. File K260150, decided April 22, 2026, lists model MJ-66DB by name, which is the X252. The indication is the appearance of full-face wrinkles, over the counter, red and near-infrared with the IEC 62471 risk group, exempt, and a 24-month warranty. You can see details on the FDA summary here.
Comfort: 4/5
Weighing 286 g, including the battery, it’s one of the lightest hard-shell LED masks, thanks to the thinness of its shell. The Shark CryoGlow (see my review) and the TheraFace Mask (see my review too) are thick, heavy, and sit away from the skin, weighing more than twice as much as the Nooance Aurion X252…
The Nooance Aurion X252’s hard shell is a step below that of the Elite X600, whose silicone shell better conforms to the contours of the face, but it is clearly an improvement over other hard-shell LED masks.
How long does the Aurion X252 battery last?
About 5 sessions per charge in my use. On 4 sessions a week I had to plug it in once a week, and a full charge takes more than one hour (using USB-C). The battery lives in the forehead, which is what makes the LED mask cordless and light, but it’s a 1,200 mAh cell.
When it runs low the power button starts blinking. That’s the only signal you get: there’s no display, so the session ends when the LED mask switches itself off at 10 minutes, and you never see the time left. It’s a detail, but it’s why this is a 4.
Are the eye shields necessary on the Aurion X252?
Not according to Nooance, but I prefer to use them. The silicone shields are in the box and clip into the eye sockets from the inside, and at 45 mW/cm² a session without them tires my eyes. With them in, I feel nothing.
Value: 4/5
$449, with a 24-month warranty, an FDA filing for this model, and an independent study. In comparison, the Elite X600 costs $749, and it performs better on every criterion I evaluate: more LEDs, 5 mW/cm² more red light, a more powerful battery, a flexible shell that fits the face better…
The question, then, is whether you’re willing to pay an extra $300 for better features or if you’d rather settle for good features.
If so, buy the X600. Otherwise, the X252 will suit you just fine, but with 174 fewer light points and no crow’s feet treatment.
My code TESTEMILIE15 takes 15% off either one on Nooance shop, and it’s a paid link: I earn a commission if you use it. You’ll find all the details and Nooance promotions on my Nooance discount code page.
Safety & support: 4.5/5
Approved by the FDA under this model number, classified in the exempt group of the IEC 62471 standard in the manual, and accompanied by a manual that clearly lists the contraindications for light therapy.
It is also recommended to perform a 5-minute test on the arm before the first session.
Support includes a 24-month warranty and a responsive email address, support@nooanceparis.com. So on safety & support, Nooance is doing right.
Who shouldn’t buy the Nooance Aurion X252
Skip this one if you recognize yourself
- Crow’s feet are the reason you are buying an LED mask. No emitter sits on that zone here, it’s lit from the side.
- You want the highest density of LED. 126 light spots is not as high as you can expect.
- You can affort a more expensive LED mask. There are better LED masks for higher prices.
Am I still using the Nooance Aurion X252?
Updated September 2026. No. When the 8 weeks ended I went back to the Elite X600, because I own both and it covers more of my face with the same light.
What I still want to know about the Nooance Aurion X252
I would love to see what the crow’s feet looked like at day 90 in the GREDECO study, because an 11.5% reduction on a zone the LED only reach from the side can be a good argument for the X252.
If that zone is your priority, the Elite X600 review is where I’d go next. If it isn’t, and $449 is your ceiling, the X252 is the LED mask I’d buy at that price.
Nooance Aurion X252 LED mask: your questions
Is the Nooance Aurion X252 FDA cleared?
Yes. The file is K260150, decided April 22, 2026, and it lists model MJ-66DB, which is the Aurion X252, by name. The applicant is Nooance itself. Cleared means the FDA accepted that it’s substantially equivalent to a device already on the market, which isn’t the same thing as FDA approved.
Does the Aurion X252 have 252 LEDs or 126?
Both are true. There are 126 light points on the shell, and each one holds a 633 nm diode and an 830 nm diode, which Nooance prints as 126 red LEDs and 126 near-infrared LEDs. I score coverage on the 126, because that is what touches your skin.
How long does the Aurion X252 battery last?
About 5 sessions of 10 minutes on one charge in my use, and a full charge takes 90 minutes on USB-C. The power button blinks when the battery is getting low.
Aurion X252 or Elite X600: which Nooance LED mask should I buy?
The Elite X600 does better on every criterion I score, with 300 light points instead of 126, 50 mW/cm² instead of 45 and a much bigger battery, and it costs $300 more at list price. Buy the X600 if the budget is there. Buy the X252 if $449 is your ceiling and crow’s feet aren’t your first concern.
Does the Aurion X252 cover crow’s feet?
Not directly. The last row of emitters sits on the rim of the eye socket, so the crow’s feet get light from those neighbors at an angle rather than from an LED placed on them. Nooance’s study still reports an 11.5% reduction on that zone at day 90, but it publishes no photo of it.

About Emilie
I have tested LED masks since 2023. I buy the devices, use them for weeks, and read the spec sheets nobody reads, because this market runs on numbers most brands never publish. Not a dermatologist, and I say so whenever a question needs one.
