FDA-Cleared Red Light Therapy Devices: What the Label Means
"FDA cleared" on a red light device means the company sent the FDA a 510(k) submission and the FDA agreed the device is substantially equivalent to one already on the market for the same use. It is a real review, and it is limited in scope: the clearance covers the specific uses written into it, such as wrinkles around the eyes or mild to moderate acne, and nothing beyond them. It is also different from "FDA approved", which red light devices almost never are, and very different from "FDA registered", which involves no review of the device at all. This article sets out what each label means, which kinds of red light devices get cleared, and how to look one up.
What does FDA cleared mean for a red light therapy device?
The FDA has reviewed a 510(k) for the device and found it substantially equivalent to a legally marketed device, called the predicate.
To be substantially equivalent, the new device has to have the same intended use as the predicate. Its technology has to be either the same, or different in ways that do not raise new questions of safety and effectiveness. When the FDA agrees, it issues a letter that clears the device for sale. FDA on the 510(k) process. Almost all FDA-cleared red light therapy devices, whether masks, panels or laser caps, have gone through this route, because they sit in Class II, the moderate-risk class.
FDA cleared vs FDA approved vs FDA registered
Cleared means a 510(k) was reviewed. Approved means a full premarket approval, which is for Class III devices. Registered means only that a company told the FDA it exists.
| Label | What happened | Used for red light devices? |
|---|---|---|
| FDA cleared | 510(k) reviewed; device found substantially equivalent to a predicate for the same use | Yes, this is the usual one |
| FDA approved | Premarket approval (PMA): the FDA evaluates safety and effectiveness directly, for Class III devices | Not the usual route for consumer red light devices |
| De Novo | A new, low to moderate risk device with no predicate gets its own classification | Only for a new kind of device with no predicate |
| FDA registered or listed | The company registered its facility and listed its products; no review of the device | Common, and often mistaken for approval |
Registration is the one to watch. Federal regulations say it "does not in any way denote approval" of the company or its products, and the FDA states that it does not issue registration certificates. FDA on "registered" and "certified". A certificate with an FDA logo on a listing does not show that anyone at the FDA looked at the device.
Cleared devices also should not be called approved. The regulation on 510(k)s says a clearance does not denote official approval and that implying otherwise is misbranding. 21 CFR 807.97. When you see "FDA approved red light therapy mask", the seller has usually either got the term wrong or chosen it on purpose.
Which kinds of red light devices get FDA clearance?
Each cleared device is filed under a product code that names what it is for. These are the codes you meet most often with red light products.
| Product code | FDA's name for it | Typical device |
|---|---|---|
| OHS | Light based over the counter wrinkle reduction | Red and near-infrared face masks and wands |
| OLP | Over-the-counter powered light-based laser for acne | Blue light acne masks and spot devices |
| OAP | Laser comb hair growth device | Laser caps, helmets and combs |
| NHN | Light-based laser, non-heating, for adjunctive use in pain therapy | Pain relief pads and some panels |
| ILY | Infrared lamp, therapeutic heating | Infrared heat lamps (exempt from 510(k)) |
The first two fall under 21 CFR 878.4810 and the last three under 21 CFR 890.5500, according to the FDA's product classification database. A mask with both a red and a blue mode can be cleared under more than one code. You can see the codes on any clearance record, which makes them a quick way to check what a device was cleared for.
What is an FDA-cleared red light therapy mask cleared to do?
Whatever its "indications for use" say, and no more. For masks, that is usually wrinkles, acne or both.
Indications are written into the clearance. One LED face mask cleared in 2025, for example, lists "the treatment of full-face wrinkles", "treatment of mild to moderate acne on the face" for its blue mode, and, for its near-infrared mode, "temporary relief of minor muscle and joint pain, arthritis and muscle spasm". Clearance summary. Other devices are cleared more narrowly, for wrinkles around the eyes only. A mask cleared for wrinkles is not thereby cleared for hair growth, rosacea or anything else, whatever the marketing around it implies.
That is also why the research behind the uses matters more than the badge. For wrinkles, the trials we rely on, a 2014 study of 113 volunteers and a 2007 split-face study of 76, measured smoother skin and higher collagen density over weeks. What to expect for fine lines covers them. For acne, the evidence is for blue light, as explained in red light therapy for acne.
Do all red light therapy devices need FDA clearance?
No. A device sold only for general wellness, and judged low risk, can be sold without premarket review. That is how many red light products reach the market.
The FDA's policy on general wellness products, most recently updated on 6 January 2026, covers products intended only for general wellness that present a low risk to users. FDA guidance. It asks, among other things, whether the technology carries risks such as those from lasers, and it gives a laser product that claims to rejuvenate skin as an example of something that would not count as low risk. The guidance does not mention LEDs. In practice, two devices with similar wavelengths can be regulated differently depending on the claims their makers make. So a missing clearance does not by itself mean a device is unsafe; it means nobody submitted it for review against a stated medical use.
How do you check whether a red light device is FDA cleared?
Search the FDA's public 510(k) database. It is free and is the closest thing there is to a list of FDA-cleared red light therapy devices.
- Open the FDA 510(k) database.
- Search by 510(k) number if you have it. Clearance numbers start with K followed by six digits.
- Without a number, search by product code, such as OHS for wrinkle devices, and narrow it by device name or decision date.
- Open the record. It shows the device name, the company that submitted it, the product code, the regulation, the decision and its date, and a link to the summary.
- Read the indications in the summary. That is what the device was cleared for.
What FDA clearance does not tell you
It does not rank devices, it does not tell you the dose you will get, and it does not cover uses outside the indications.
A 510(k) compares a device with a predicate; it is not a head-to-head test of which mask works best. It says nothing about whether one device delivers more light at the skin than another, which is why we publish irradiance figures and suggest you look for them on any device you consider. Why LED count is the wrong number to shop by goes into that. And clearance does not make a device risk-free. In 2019 a widely sold acne light mask was voluntarily recalled over a theoretical risk of eye injury for people with certain eye conditions or taking light-sensitising medication. Recall notice. The precautions still apply to cleared devices, and eye safety comes first; see is red light therapy safe for your eyes.
Where does the Kivorla mask stand?
The Kivorla 4-Wavelength Red Light Therapy Mask is FDA cleared, and we describe it as cleared, never approved.
It has two modes. The red mode runs 665 nm red with 850 nm and 1064 nm near-infrared, and the blue mode runs 460 nm blue with 850 nm near-infrared. Its irradiance at the skin, 50 to 103 mW/cm², is on the product page, along with the session limits from the manual: 10 minutes up to four times a week at high brightness, or 15 minutes up to three times a week, never more than 20 minutes a day. The eye area is an open cutout with no diodes over it. The clearance is a good place to start, but we would still rather you judged the mask on the published numbers and the studies behind them.
The 4-Wavelength Red Light Therapy Mask page has the full specification. Before ordering, read the precautions, and note that returns are accepted within 30 days, less a 10% restocking fee if the mask is unopened with its seals intact, or 20% if it is opened but undamaged and complete. Standard shipping to the US, UK and Germany is free.
