FDA cleared, CE, UKCA: what the labels mean

The short version

UKCA and CE marks

To be sold in Great Britain, electrical products like LED masks need a conformity mark. Great Britain currently accepts either the UK's UKCA mark or the EU's CE mark for most products [1]. The mark goes with a declaration of conformity: a document in which the maker lists the rules and standards it says the product meets.

• It's mostly self-declared. For electrical products, UK rules let the manufacturer declare conformity itself [1]. No regulator tests the product before sale.
• It's about safety, not results. The rules cover electrical safety, radio and electromagnetic interference, and hazardous substances. They don't cover whether a mask improves skin.
• Look for a name and address. The manufacturer's and importer's name and postal address should be on the product (or, in some cases, its packaging or paperwork) [1]. Masks without a traceable company are harder to return or report.
• "CE certified" on a web page is less useful than the mark and declaration themselves. Ask for the declaration of conformity if it isn't in the manual.

MHRA registration and medical claims

In Great Britain, whether a product is a medical device depends on its intended purpose, as shown by what the maker says in its labelling and marketing. Products without a medical purpose, including wrinkle treatments with a cosmetic purpose, are not normally medical devices. A "this is not a medical device" disclaimer doesn't help if the marketing makes medical claims [2].

Medical devices must be registered with the Medicines and Healthcare products Regulatory Agency (MHRA) before they're sold in Great Britain, and makers based outside the UK must appoint a UK Responsible Person [3]. So an LED mask sold for cosmetic purposes, to improve how skin looks, doesn't need registering, but it can't then claim to treat conditions.

In November 2025 the MHRA told the BBC "there are currently no LED face masks currently registered" [4]. The same day, the Advertising Standards Authority (ASA) upheld complaints against four companies whose ads claimed their masks treated acne or rosacea [4]. In two of those rulings, the ASA said it had "seen no evidence that the product was registered with the MHRA or had the appropriate conformity marking" [5] [6].

This is why UK pages talk about "the appearance of blemishes" rather than "treating acne". 3 masks in our directory are from brands with an upheld ASA ruling, shown on their listings.

Some brands say their masks are certified under the EU Medical Device Regulation (MDR). That's an EU status. In Great Britain, check the MHRA's register [7].

"FDA cleared" and "FDA approved"

The US Food and Drug Administration (FDA) has no role in the UK, but its clearances appear on many UK product pages. Most LED masks that have one went through the 510(k) route: the maker shows the FDA that its device is "substantially equivalent" to one already legally sold in the US. That's a lower bar than approval, and it doesn't usually require new clinical trials.

• "Approved" usually means "cleared". Several brands and magazines call masks "FDA approved". For these products, the status is almost always a 510(k) clearance.
• Check the number and the name. Each clearance has a number starting with K, a device name and an applicant, all searchable in the FDA's database [8]. Two brands in our directory, Omnilux and The Light Salon, cite the same number, K191629, which the database lists under the device name "faceLITE LED mask". They may share a manufacturer, but the clearance names neither brand.
• Check the model. A clearance can cover an earlier version, or a family of models. Where a brand's own pages disagree about which mask is cleared, our listings show "Sources differ".
• "FDA registered" or "FDA listed" means the company has registered with the FDA. It involves no review of the product.

We've confirmed 7 masks' clearances directly in the FDA database. For 4 more, the brand's claim and the FDA record don't clearly match.

Safety standards

Manuals and declarations often list international standards. They show what a brand says it has tested against, though test reports are rarely published. The ones you'll see most:

IEC 60601-1 (and -1-2, -1-11)

Electrical safety for medical electrical equipment, its electromagnetic compatibility, and use in the home.

IEC 60601-2-57

Extra safety requirements for non-laser light equipment used for therapeutic, diagnostic, monitoring or cosmetic purposes [9].

IEC 60601-2-83

Extra safety requirements for home light therapy equipment used by lay people, covering all light sources except lasers [10].

EN 60335 (-1, -2-27)

Safety of household electrical appliances; part 2-27 covers appliances that expose skin to optical radiation [11]. Some brands use this appliance route instead of the medical one.

IEC 62471

Photobiological safety of lamps: places a light source in a risk group for eyes and skin, from "exempt" to "high risk" [12]. The risk group is the useful part, and few brands state it.

ISO 10993

Biological safety of materials that touch the body [13]. For a face mask, the relevant parts test whether the materials irritate the skin or cause allergic sensitisation.

IEC 62133

Safety of rechargeable lithium batteries, under normal use and reasonably foreseeable misuse [14].

What UK masks declare

Based on manuals, product pages and declarations we could read. "Not found" can mean the information exists but isn't published online. Each listing shows the detail and our sources.

How to check for yourself

1. Look for the UKCA or CE mark on the product, box or manual, and a UK or EU company name and address.
2. Ask for the declaration of conformity if it isn't published.
3. If a page claims to treat a condition, search the MHRA's register for the device [7].
4. For "FDA cleared", find the K number and check the device name and applicant in the FDA database [8].
5. For eye safety, ask which IEC 62471 risk group the mask falls into.
