Sources differ: UK help centre: 100 mW/cm². FDA 510(k) summaries K243492/K260511: 1–40 mW/cm². Amazon UK (brand seller): '100W/cm²'. None states measurement conditions.
Three different figures. UK help centre: 'The mask delivers an LED treatment intensity of 100mW/cm²'. Both FDA 510(k) summaries (submitted by Ulike): 'LED Intensity 1-40mW/cm2'. Amazon UK listing (sold by Ulike Beauty Care): 'delivering a 100W/cm² energy output' (units as written). None gives distance, measurement points, instrument, or whether the figure is per band, per mode or combined. The UK product page gives no mW/cm² figure, only '77.4% better light irradiance' from its mirror-reflection design, with no baseline or method stated. K260511 lists a 'Wavelength and Irradiance Performance Test Report', which is not published.
Light-output figures come from the manufacturer. Independent checks are rare, even in published studies, so treat them as claims. Why
Sources differ: Product page: max 20 minutes per session. Quick-start guide: max 26 minutes a day. Help centre: 20 per session, 26 maximum.
Daily maximum differs. UK product page: 'not exceeding 20 minutes in total' per session. Quick-start guide: 'should not use the device for more than 26 minutes a day'. Help centre gives both: 20 minutes per session, 26 minutes maximum. See conflicts.
Sources differ: UK product page FAQ: 3 times a week. Quick-start guide and help centre: up to 6 times a week, or daily once skin is used to it.
UK product page FAQ: 'It is recommended to use the device 3 times a week.' Quick-start guide: 'up to 6 times a week… Once your skin gets used to the device, you can use it every day.' Help centre: 'up to 6 times per week', with a '28-day treatment cycle'.
In K260511, Firm is called 'Anti-Aging mode' and Rejuvenate is 'Restoring mode' (US filing).
Help centre: 'The mask body itself does not charge directly.' Spec table says 'Wireless Use Support: Yes', meaning no mains cable during use (the controller is still cabled to the mask). The help-centre unboxing photo shows a US-style plug. UK plug/adapter not confirmed.
Sessions per charge not stated.
UK page: 'Built-in silicon eye seal minimizes light exposure around the eyes'. Quick-start guide labels a 'Protective eye guard'. 510(k): 'protective eye-shield which blocks light energy from LEDs'. Quick-start FAQ: 'The light emitted by the LED mask has no effect on eyesight and is harmless to the human body' (claim, not verified).
Amazon UK (sold by Ulike Beauty Care): item weight 0.45 kg, item 23.3 × 19.1 × 14.5 cm; package 1.25 kg, 26.2 × 24 × 20.2 cm. Brand site gives no weight. Unclear if 450 g includes the controller.
No app mentioned. NFC tag on the mask is for an 'Anti-Counterfeiting' check that opens a browser page on the phone.
No app or paid features mentioned.
Battery sits in the separate controller, but no source says whether the battery or the controller can be replaced or bought separately.
Values are as stated by Ulike unless marked otherwise.

Tested, not included
One-paragraph mention under 'Other LED masks we've tested'. Price quoted $399. US buying guide by Nasha Addarich Martínez and Anna Gragert; masks chosen from brands with FDA clearance and tested by the authors. Article carries an affiliate disclosure; prices in US dollars. Text supplied by the site owner.
'UKCA-cleared' is unusual wording: UKCA is a self-declared conformity mark, not a clearance. No declaration of conformity, UK responsible person, or regulation (medical device vs. general product) given. Ask.
Ulike markets it with medical-sounding claims (acne treatment, 'FDA cleared') and US filings use medical-electrical standards. UK classification and registration not established. MHRA told the BBC on 5 Nov 2025 that 'there are currently no LED face masks currently registered'. Registration can be checked on the MHRA Public Access Registration Database (PARD); not yet checked for this model.
UK page says 'FDA-cleared' and 'FDA cleared… home use device'. Device name, model and applicant match. K260511 is a modification: extra battery and LED suppliers 'with the same specifications', plus a package without an adapter. US status only — not a UK approval. Whether the UK unit is identical is not confirmed.

Declared in the US 510(k) summaries (submitted by Ulike), not in any UK document we found. IEC 62471 risk group not stated. Test reports not published. UK page says only 'Tested in SGS Laboratories'.
A conformity mark or US FDA clearance doesn't prove a device works. "Not published" doesn't mean unsafe. If you have a medical condition, are pregnant or take light-sensitising medicines, ask your GP or pharmacist first.
Runs from delivery date. Covers defects in materials/workmanship. Ulike repairs or replaces at its option and sends a pre-paid label. Replacements are covered for the unexpired period only. Not transferable to second owners. Excludes unauthorised sellers and free gifts. Warranty can be voided 'if the Product is used outside the market where it is purchased'. Claims need proof of purchase, order number, model and serial number (SN is on the mask next to the controller port). Statutory rights unaffected.
Sources differ: Price match: '7-Day' (product page, policy) vs '14-Day' (/pages/ulike-reglow landing page). 100-day guarantee shown on ReGlow page, but the policy intro limits it to 'any Ulike IPL device'.
Brand-site purchases only; Amazon and other retailers handle their own returns. The policy intro says the 100-day guarantee applies 'when you purchase any Ulike IPL device', but the ReGlow page shows '100-Day Money-Back' — ask whether it covers the mask. Product page badge says '7-Day Price Match'; the /pages/ulike-reglow landing page says '14-Day Price Match'; policy section 9 says 7 days. Standard UK delivery 2–3 business days; express £4.99.
Only a 7-page QUICK START GUIDE (image-only PDF), and the file title marks it as the US version. It has no spec table, warnings, manufacturer address or conformity marks. Linked from Ulike's US blog, not the UK site. The full 'User Manual' shown in the box (cover reads 'Version 1.0, Effective date 2024/01/10') was not found online. Help-centre spec table used for specifications instead.
Sources differ: Help centre lists a charger. K260511 adds a package with only a Type-C cable and no adapter. Help-centre unboxing photo shows a US plug.
