How do I tell if an "FDA cleared" mask is real?

Look for a K number (K plus six digits) on the listing or box. Search it in FDA's 510(k) database. Check that the model number on your mask is in that filing. Then read what it is cleared for. In our check, only 9 of 24 Amazon masks that say "FDA cleared" had a filing for that exact mask.

Does a mask under $100 work?

Maybe a little, if you use it for 2 to 3 months. Neither the Weltallina's nor the BONLIBRO's FDA filing has a results trial on people; FDA cleared them because they work like masks already sold. The American Academy of Dermatology says red light devices "can produce subtle to noticeable results on the face" in some studies.

How long should a session be?

Follow the FDA filing, not the listing. The Weltallina's filing says 5 minutes, 3 days a week, and "DO NOT exceed 5 minutes in one session." Its listing says 10 to 20. The BONLIBRO's filing allows 5, 10 or 20 minutes.

Is it worth spending more?

Our LED guide's other picks cost more and are listed by brand in FDA's records. See the guide.

What about the Pure Daily Care Luma, iReliev and Skin Gym WrinkLit masks?

FDA's device listing names the Pure Daily Care LUMA mask, model E43, under K243555 (the RENPHO's filing). The Luma on Amazon gives no model number, so check the box for E43. FDA's records list iReliev pain devices and a red light laser, but no iReliev face mask. They list a Skin Gym Pro mask (K221775), but not the WrinkLit. We found no filing for either of those two masks.

Is the INIA mask FDA cleared?

Not that FDA's records show. Its model number, IN-FM002, is one of nine in a factory's filing (K243040), but no FDA record lists INIA, and the INIA listing makes no FDA claim.

What does it cost per session?

About $0.46 for the Ulike, if you use it 3 times a week for a year (156 sessions).

Is it safe for darker skin?

Ask a dermatologist first. The American Academy of Dermatology says people with darker skin "are more sensitive to visible light, such as red light," which "can lead to hyperpigmentation."

01 / The FDA check

Most cheap masks that say "FDA cleared" do not check out

We checked the 74 best-selling LED face masks on Amazon against FDA's records. 24 of the 71 still for sale said "FDA cleared." Only 9 had an FDA filing for that exact mask. Read the full check.

Under $100 today: 19 of those masks are on sale for less than $100. 5 say "FDA cleared." None of those 5 has a filing for that exact mask. The Ulike ReGlow Lite is not one of them: its listing makes no FDA claim, while FDA's own device listing names it.
Why it happens: one factory files with FDA, then many brands sell its mask. A brand can copy the factory's K number without FDA's records ever listing that brand.
"FDA approved" is the wrong word. FDA clears LED masks; it does not approve them. A clearance means FDA found the mask about as safe as one already sold. The American Academy of Dermatology says FDA cleared "doesn't tell you anything about how effective the device is."

How to spot a fake FDA claim in 2 minutes

Find the K number. It is a K plus six digits, on the listing, box or manual. No K number? Ask the seller. If they cannot give one, assume it is not cleared.
Search it in FDA's 510(k) database and open the PDF.
Match the model. The model number on your listing or box must be in the filing. Weltallina's is SR-M4; BONLIBRO's is M19-6.
Read "Indications for Use." That is what the mask is cleared for: wrinkles, acne, or only heat for sore muscles.
Compare the listing to the filing. Session time, light colors and light strength should match. When they do not, follow the filing.

03 / Does it work?

What a cheap cleared mask can and cannot do

FDA cleared these masks by comparing them with masks already sold. Neither filing has a results trial on people.

Weltallina's filing: "Clinical/animal testing was not performed for the proposed device as part of the submission." It is cleared for "the treatment of full-face wrinkles" (red light) and "mild to moderate acne on the face" (blue light). Its near-infrared mode is cleared only for heat, for "minor muscle and joint pain."
BONLIBRO's filing: The filing lists only non-clinical tests. It is cleared for "Treatment of full-face wrinkles" (red plus infrared, and yellow plus infrared) and "mild to moderate inflammatory acne" (red, blue and infrared).
Dermatologists: the American Academy of Dermatology says red light devices "can produce subtle to noticeable results on the face" in some studies, and "we don't know the long-term effects on the skin." AAD
