I own both Nooance LED masks, the Aurion X252 at $449 and the Elite X600 at $749, and I tested them one after the other: 36 sessions over 12 weeks with the Elite X600, then 32 sessions over 8 weeks with the Aurion X252. They share the same wavelengths, so what separates them is the number of LEd and light points, the shape of the shell and technical details.
So here’s my side-by-side comparison of the Nooance Aurion X252 and the Elite X600, with both scores and the one I kept using.

Nooance Aurion X252 or Elite X600: my verdict by buyer
Buy the Aurion X252 if $449 is your ceiling, and you care about tone, texture and radiance before crow’s feet, because this specific area is not well covered by the Aurion X252. You can also appreciate the cordless LED mask, although the battery is far smaller.
Buy the Elite X600 if you want an LED mask that will last for years, or if the eye area is your priority, because it has 300 light points on a soft shell that goes all the way around the eyes and under the chin. It is clearly the top-of-the-line model in the Nooance LED mask lineup.
Buy neither if you’re looking for blue light to work on breakouts, although blue light is not as much studies than red et infrared. Both LED masks carry red and near-infrared only.
What I tested: the Nooance Aurion X252 and the Elite X600
Nooance sent me the Elite X600 for free ahead of its US launch, and I bought the Aurion X252 with my own money. I’m now a Nooance partner: the code TESTEMILIE15 gives you 15% off and I earn a commission on it, which has no effect on the scores below.
I started with the Elite X600, 3 sessions of 10 minutes a week for 12 weeks, which is the routine Nooance recommends for it. The Aurion X252 came next, at 4 sessions a week for 8 weeks, and I bought it at $449 on Nooance’s US shop.
Results: Aurion X252 4/5 · Elite X600 4.5/5
My results with Aurion X252
When I put the Aurion X252 on for the first time, my skin already had more than a year of red light therapy behind it, including the Elite X600 testing period…
After 8 weeks, I didn’t notice any difference in the photos, but I didn’t lose any benefits either, and that’s already a good sign. With less powerful LED masks, I saw my skin deteriorate during the test.
Aurion X252: what Nooance’s study reports
The Aurion X252 has its own clinical study, run by the French laboratory GREDECO on 20 women of 58 on average. Nooance publishes the measurements but no before and after photo, so for this model I only have numbers to show you below.
Elite X600: my before & after
The half point comes from here. After 12 weeks with the Elite X600 my skin tone was more even on the cheeks, I had less redness around my nose and my pores looked tighter, and this time it shows in the pictures.
Elite X600: what Nooance’s study reports
GREDECO also ran the Elite X600 study, with 21 women between 35 and 65, and this one comes with before and after photos of the eye area and of the skin texture. Here are both studies next to each other, with every figure published by Nooance at day 90.
| Published by Nooance | Aurion X252 | Elite X600 |
|---|---|---|
| Protocol | D118.9.25 | D125.9.25 |
| Volunteers | 20 women, 58 on average | 21 women, 35 to 65 |
| Sessions | 5 a week, 90 days | 3 a week, 90 days |
| Crow’s feet | -11.5% | -8% |
| Nasolabial folds | -9% | -13% |
| Elasticity | +21% | +23% |
| Dermal density | +58% | +42% |
| Before and after photos | Not published | Published |
You’ll notice the Aurion X252 gets the better figure on crow’s feet and on density. But its volunteers were older and spent 50 minutes a week under the LED mask against 30 for the Elite X600 group, so those higher percentages don’t mean it’s the stronger of the two, and you will understand this in the next criteria.
But in both cases, the results are very positive, with measurements that are more accurate than those of most competitors.
Irradiance: Aurion X252 4.5/5 · Elite X600 4.5/5
Aurion X252: 45 mW/cm²
For the Aurion X252 the light output (irradiance) is 45 mW/cm², published by Nooance, and the manual prints a dose of 27 J/cm² per session that matches it. The FDA summary of K260150 splits it into 30 mW/cm² of red and 15 of near-infrared.
The only thing missing is where the 45 was measured, because the X252 page doesn’t say, but considering other LED masks from Nooance are measured at the skin level, I assume it is the same here.
Elite X600: 50 mW/cm²
The Elite X600 irradiance is at 50 mW/cm², and here Nooance adds that the figure is calibrated in contact with the skin. In the same FDA summary it’s 35 mW/cm² of red and 15 of near-infrared, so the whole gap is 5 mW/cm² of red light.
That’s a small difference, and both irradiance figures sit in the 30 to 50 band I look for. Where the Aurion X252 really gives ground is on how many light points there are and where they sit, which is the next criterion.
Coverage: Aurion X252 3.5/5 · Elite X600 5/5
Aurion X252: 126 light points, 252 LEDs
The Aurion X252 has 126 light points, which is 174 fewer than the Elite X600 and less than half. You can see it as soon as both LED masks are switched on: the points are further apart, and the shell itself is smaller as it does not cover the face in depth.
The forehead, the cheeks, the nose and the upper lip are well lit. But the rigid shell stops at the jawline, so nothing reaches under the chin, and a whole line at eye level has no LED, from the eye cutout out to the temple. That line is where the crow’s feet are, and they only get the light of the rows above and below.
It’s still the weak point of this model for me, and I filmed that gap up close in my full Nooance Aurion X252 review.
Elite X600: 300 light points, 600 LEDs
This is where the Elite X600 is very strong. Its silicone shell wraps the jaw, goes under the chin and closes all the way around the eyes, with LEDs as dense there as on the cheeks. So if crow’s feet are the reason you want an LED mask, the Elite X600 is the one to buy.
The 300 light points also sit close enough for their light to overlap on the skin, which I explain with more pictures in my 12-week review of the Nooance Elite X600.
Proof: Aurion X252 5/5 · Elite X600 5/5
Both LED masks are in the same FDA file, K260150, filed by Nooance itself. It names the Aurion X252 as model MJ-66DB and the Elite X600 as MJ-66C, so neither one borrows the clearance of the other.
Aurion X252: 7 points out of 7, without study photos
I expected Nooance to have standardized documentation for its LED masks, but that is not the case. The Aurion X252 is the subject of its own study and has its own section in the filing submitted to the FDA, and its user manual specifies the dose per session.
I would simply like to see the images that go with this study to evaluate visually speaking the results.
Elite X600: 7 points out of 7, photos included
The Elite X600 goes further on 2 aspects: the study is published with its photos, and the irradiance with its measurement condition.

Comfort: Aurion X252 4/5 · Elite X600 4.5/5
Aurion X252: light and cordless, but still a rigid shell
At 286 g with the battery inside, the Aurion X252 is really good for a rigid LED mask, and it has nothing to do with the heavy models I’ve tested which weight near 800 g for some of them.
It’s still a hard shell though, and the silicone of the Elite X600 feels nicer on my skin.
The battery in the forehead makes it quick to start, since I put the LED mask on, press the button and that’s it. The downside is that I got about 5 sessions per charge, so I had to charge it every week, and with no screen I never knew how many minutes were left.
Elite X600: softer on the skin, with a timer I can see
With the Elite X600 there’s a remote which is also the battery. I prefer it that way, because the remote shows me the timer and it holds a much bigger battery: I charge it every 2 weeks, overnight since it needs about 4 hours, when the Aurion X252 takes 90 minutes every week.
The routine is lighter too. Nooance recommends 3 sessions a week with the Elite X600 and 5 with the Aurion X252, which means 30 minutes a week against 50. Still, you can use Elite X600 up to 4 times a week if you prefer, but I personnaly stick to 3 times a week.
Eye shields are included with both and I wear them with both, because at that brightness my eyes get tired without them.
Value: Aurion X252 4/5 · Elite X600 4/5
Aurion X252: $449, one of the best choices at this price
For $449 you get an FDA-cleared LED mask with its own clinical study, 45 mW/cm² and 2 years of warranty, and among the LED masks I’ve tested it’s one of the best choices at this price.
The compromises are the ones you’ve just read: fewer light points, a smaller shell and a battery to charge every week.
Elite X600: $300 more, for an LED mask you keep
The Elite X600 lists at $749. The extra $300 pays for 174 more light points, the eye contour and the underside of the chin, a softer shell and a battery more than 4 times bigger. If you really want to use an LED mask over the long run, the Elite X600 is the better buy.
It only stays at 4 because $749 is still a lot of money. My code TESTEMILIE15 takes 15% off both, and these are paid links, so I get a commission when you order through them: about $382 for the Aurion X252 on Nooance’s shop and about $637 for the Elite X600.

Safety & support: Aurion X252 4.5/5 · Elite X600 4.5/5
Aurion X252: exempt risk group and 2 years of warranty
The manual of the Aurion X252 puts it in the exempt group of IEC 62471, lists the contraindications and asks you to try it 5 minutes on your arm before you start. The warranty is 24 months.
Elite X600: the same paperwork
Same risk group, same 2 years and same brand behind the support, so I have no difference to report here. Paying less doesn’t get you a weaker warranty at Nooance, which I really appreciate.
Who shouldn’t buy the Nooance Aurion X252 or the Elite X600
Skip both if you recognize yourself
- Breakouts are what you want to work on. There is no blue light in either LED mask, and the FDA file covers the appearance of wrinkles.
- You won’t keep 3 to 5 sessions a week for 3 months. Both studies ran for 90 days, and so did my results with the Elite X600.
Am I still using the Nooance Aurion X252 or the Elite X600?
Updated September 2026. The Elite X600. I picked it up again the week my Aurion X252 test ended, and it’s the LED mask I wear 3 evenings a week.
Nooance Aurion X252 vs Elite X600: your questions
Is the Nooance Aurion X252 less powerful than the Elite X600?
Slightly. Nooance publishes 45 mW/cm² for the Aurion X252 and 50 mW/cm² for the Elite X600, and the FDA summary puts the whole difference on red light. The bigger gap is the number of light points, 126 against 300.
Are both Nooance LED masks FDA cleared?
Yes, under the same file, K260150, which lists the Aurion X252 as model MJ-66DB and the Elite X600 as MJ-66C. FDA cleared isn’t FDA approved: it means the FDA accepted each one as substantially equivalent to a device that was already sold.
Which Nooance LED mask is better for crow’s feet?
The Elite X600. Its shell closes around the eyes with LEDs on the crow’s feet, while the Aurion X252 has no light point there and lights that zone from the rows next to it.
How often do I have to charge each Nooance LED mask?
In my use, every week for the Aurion X252, which gave me about 5 sessions per charge, and every 2 weeks for the Elite X600. The Aurion X252 charges in 90 minutes and the Elite X600 in about 4 hours.
Does the code TESTEMILIE15 work on both LED masks?
Yes, it takes 15% off the Aurion X252 and the Elite X600 on Nooance’s shop. It’s a paid code, so I earn a commission when you use 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.
