The Dreame Chrona Photon Anti-Aging Skincare Mask is the first LED mask from Dreame, the brand behind the robot vacuum and mop I’m happy with at home. I used it 4 times a week for 4 weeks, on the red and near-infrared mode, at the highest intensity.
So here is my review after a month, including the real face coverage of this LED mask, and my feedbacks with the score.
38/100
Shelved since October 2026I saw nothing on my skin after 4 weeks. It’s light, and the open eye window is pleasant to wear. But I count 70 light points on the silicone, with many area not exposed to light, and Dreame does not specify its irradiance anywhere: nobody knows its light power!
Buy it if
- You want a soft, cordless LED mask you can wear with your eyes open, and you accept not knowing the light output.
- You want a 10-minute habit more than a result on your skin.
Skip it if
- You want your skin to get a real light dose.
- You already own an LED mask with more than 100 light points.
- You want your LED mask to be the subject of a clinical trial.
What I tested: the Dreame Chrona LED mask
I bought the Chrona on Dreame’s US site for $209.99, against a $299.99 list price. No affiliate link, and no contact with Dreame. The model is the AB01A, the only version they sell. The box holds the silicone LED mask, the remote, 2 swappable battery packs, a USB-C cable and a bag.
I ran it for 4 weeks in October 2026, 4 sessions a week, on the Rejuvenate mode that combines red 630 nm and near-infrared 850 nm. I left the intensity on Level III and the timer on 10 minutes, which is how the mask comes set out of the box.
Results: 2/5
What changed on my face following my test, including my before-and-after photos. I also evaluate the “before-and-after” examples provided by the brand being tested, as well as the results of any studies that may have been conducted on the mask.
Read my results guideI got no results. After 16 sessions I had no change in tone, no change in the texture along my nose, and nothing worth putting in a before and after.
I normally run 8 weeks, and 12 when something starts to show, but I stopped at 4 here because the 2 numbers that predict a result, light points and irradiance, were already below anything that has ever worked on my face.
My before&after from the Nooance Elite X600 LED mask (my review here)
Dreame publishes an SGS study on this LED mask: 130 people with Asian skin, in China, 28 days, 10 minutes every day. Dreame shows a skin elasticity up 20.87 %, but it comes only from the Red group, and there’s no control group. Moreover, the pictures “before/after” seem to be AI generated to be fair, as the results after 4 weeks are way better than expected from red light therapy…
This is not what is expected from clinical studies on LED masks, where I prefer those to be ran with instrumental measures and with a placebo group.
Irradiance: 0.5/5
How much light reaches the skin, in mW/cm²? I evaluate this value, as well as how the information is presented, the conditions under which it was measured, and the total dose received in a single session. If the brand does not communicate it, I give it a severe rating.
Read my irradiance guideDreame doesn’t publish any information about the irradiance, which is the light power of the LED mask. No information on the US product page, not on the global page, not in the manual…
- Dreame Chrona not disclosed
- Nooance Aurion X252 45
- Nooance Elite X600 50
- CurrentBody Series 2 30
- Shark CryoGlow 64
Instead, the LED mask features 3 intensity levels and 3 duration settings (5, 10, or 15 minutes), both of which can be adjusted using the remote control. The “Low” setting is noticeably less intense than the “High” setting.
The problem I have with this Chrona LED mask is that we have no information about the light dose (fluence) received. In light therapy, the dose is calculated by multiplying the irradiance by the session duration (irradiance x time). But here, we have no irradiance data, and the duration is variable…
In their study, Dreame states that the masks operated at the default setting of 10 minutes, which is why I stuck with that same setting, and I recommend doing the same.
Coverage: 1.5/5
How many points of light does the mask actually feature, how evenly are they distributed, and which areas remain uncovered? Note that I am counting “bulbs” and not LEDs, because the number of LEDs often includes two, three or more diodes per bulb, which inflates the apparent coverage area.
Read my coverage guideDreame Chrona: 280 LEDs or 70?
I count 70 light points on the silicone (and you can too). Dreame says 280 LEDs, and its true: it uses “quad-chip LEDs” for 70 bulbs with 4 chips each. The 5 colors on 4 chips puzzled me until I read the specs, which describes the Brighten mode as “yellow light = red + green”. So the yellow you see is 2 chips lit together, which is far from a real 590 nm the manual suggests…
70 points to cover the whole face is a problem. The Nooance Aurion X252 has 126, the Shark CryoGlow 160, the Nooance Elite X600 300, and 70 spread over a whole face leaves gaps between beams, so the skin is not properly covered.
- Dreame Chrona 70
- Nooance Aurion X252 126
- Shark CryoGlow 160
- Nooance Elite X600 300
The shape of Dream Chrona LED mask
Flexible silicone is more comfortable than a rigid LED mask, which is a point I already highlighted in my review of the JOVS 4D LED mask (which bears a strong resemblance to the Dreame…).
However, Dreame states on its product page that the mask sits 1 cm away from the skin, which clearly reduces the light intensity actually received.
There is also a coverage issue due to the mask’s shape; the wide eye opening leaves certain areas uncovered.
Proof: 2.5/5
What the brand clearly displays and what I check in the FDA file: wavelengths (in nm), emitted dose, FDA clearance number, product study, safety tests, warranty.
Read my proof guideWhat Dreame publishes
- Published: Wavelengths in nm
- Missing: Dose per session calculable in J/cm² from the published data
- Missing: FDA clearance number cited and verifiable in the database
- Published: Clinical study on this model
- Published: Documented study: sample size, duration, named laboratory
- Not disclosed: Photobiological safety declared
- Published: Warranty and support documented
Proof: 2.5/5
The SGS report is a key highlight for Dreame, and a score of 4 out of 7 would normally correspond to a rating of 3.
However, I am deducting half a point due to the lack of an FDA filing: this LED mask is not FDA-cleared.
Dreame’s global page says “FDA registered”, which means a company filed a form and nobody reviewed the device yet. I searched the 510(k) database for Dreame, for Chrona and for AB01A, and there’s no clearance under any of them. Registered is the word that matches the record.
Then the colors. Yellow 590 nm for brightness and green 530 nm for redness are 2 of the 5 modes, and FOREO, which sells both, prints on its own page that green and yellow are not intended to have a medical effect.
I have already shared my thoughts on these “new” colors in my review of the FOREO FAQ Swiss 202 LED mask. Regarding Dreame, the SGS study includes no “green” group, and no study demonstrates convincing effects for these colors, which I view as a marketing ploy.
Comfort: 3/5
Fit, weight, heat, eye comfort and minor inconveniences: straps, timer, battery. A mask that becomes a chore to wear several evenings a week scores poorly in these areas, as using it should be a pleasant experience!
Read my comfort guideWeighing 338g and made of soft silicone, with no cable and an eye opening, I find this Chrona LED mask quite comfortable to wear. I can watch my phone or TV without any problems. However, the mesh around the mouth lets in very little air, and after 10 minutes, I found it oppressive. The LED panel gets a little warm at the end of a session, but that’s been the case with all the LED masks I’ve worn, and it’s never bothered me.
Can you keep your eyes open in the Dreame Chrona?
Yes, but a little light still gets through the opening, enough to make my eyes slightly tired by the end. It’s still acceptable, but the silicone pad needs to be positioned correctly to minimize the light. I actually saw a client with her eyelids closed, and quite a significant amount of light was getting through.
Value: 2/5
The price I paid, when viewed in the context of the results achieved and compared to other masks I have tested, both within this price range and at different price points.
Read my value guideI paid around $210, and Dreame lists the Chrona at $299.99 between promotions. For this price, you get 70 LEDs, 5 colors (2 of which aren’t validated), and no information on irradiance. The price is low, that’s for sure, but the compromises are too restrictive even at this price point.
For comparison, the Nooance Aurion X252 LED mask (I reviewed it here) costs $449 and brings 126 light points, an irradiance of 45 mW/cm² (published data), FDA clearance, and a rating of 84/100 from me.
It’s more expensive, but with my Nooance discount code, the difference is less significant. So, if the Chrona fits your budget, I’d advise you to wait and buy the X252 directly instead.
Safety & support: 2/5
Eye protection, build quality, warranty, returns, responsiveness of customer support, and the mask’s ability to remain functional over time.
Read my safety & support guideDreame offers a 2-year limited warranty and a 30-day return policy. The manual is adequate: it includes a 3-minute light sensitivity test on the forearm before first use, a list of contraindications, and a warning against applying retinol or acids to the skin before a session. These are common contraindications for red light therapy, regardless of the mask used.
However, the manual makes no mention of eye safety, and given that the eye protection only works if the device is positioned correctly, I can’t give it more than 2 stars.
Who shouldn’t buy the Dreame Chrona
Skip this one if you recognize yourself
- You wear contact lenses. Dreame’s manual says to avoid them with this LED mask, and the open window is why.
- You are expecting a certain dose of light therapy. No irradiance is published, and the remote lets you change both the intensity and the duration.
- You already own an LED mask with more than 100 light points. The Chrona has 70, held 1 cm off your skin, and it would be a step down.
Am I still using the Dreame Chrona?
Updated November 2026. I stopped at the end of the 4 weeks and I do not recommend you to use this LED mask. The price is its only selling point, but it is explained by its poor features.
What I still want to know about the Dreame Chrona
The irradiance of each of the 3 levels, measured at the skin level considering that 1cm gap.
A 510(k) number to look for their FDA folder.
And whether the yellow mode is a 590 nm chip, as the manual says, or red plus green lit together, as the SGS report says.
Dreame makes robot vacuums that I would recommend without hesitation, but their LED mask is another story, and I am disappointed that such a competent brand offers such a poor quality LED mask.
Dreame Chrona LED mask: your questions
Is the Dreame Chrona FDA cleared?
Dreame’s US page says “FDA-cleared”, its global page says “FDA registered”, and I found no 510(k) under Dreame, Chrona or AB01A in the FDA database. Registered means a form was filed, not that the device was reviewed.
How many LEDs does the Dreame Chrona really have?
I count 70 light points on the silicone. Dreame’s 280 LEDs comes from 4 chips inside each bulb, which the brand calls “quad-chip LEDs” on its own product page.
What is the irradiance of the Dreame Chrona?
Not disclosed. There is no mW/cm² figure on Dreame’s product pages or in the manual, for any of the 3 intensity levels.
Can I keep my eyes open with the Dreame Chrona?
I did for all 16 sessions. A little light gets in around the window and tired my eyes slightly by the end, and the manual says not to look directly at the light, so the silicone pad has to be seated with care every time.
Which mode and setting did I use for my test?
Rejuvenate, which combines red 630 nm and near-infrared 850 nm, on Level III for 10 minutes. That is the setting the mask ships with, and I ran it 4 times a week for 4 weeks.

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.
