Sources differ: Manufacturer: 120 LEDs. Lookfantastic: '120 … LEDs (480 LED light bulbs)'. Guardian: 480 LEDs at 120 light points.

Sources differ: UK page spec table: 465 nm. Page mode description and Lookfantastic: 463 nm.

Sources differ: Page FAQ: 'Dark red LED light is 660nm'; no mode or spec row includes 660 nm (red is 633 nm).

Light output (irradiance)

Mode1 red: 23.1; Mode2 blue: 16.1; Mode3 amber: 16.6; Mode4 near-infrared deep near-infrared: 11.7–24.7; Mode5 red near-infrared deep near-infrared: 26.8–32.3; Mode6 blue red near-infrared deep near-infrared: 24.8–26.1; Mode7 amber red near-infrared deep near-infrared: 22.6–26.3mW/cm²

How it was measured isn’t published. Manufacturer-stated

Dose per session

Mode1: 10.3; Mode2: 9.9; Mode3: 10.5; Mode4: 11.8–15.1; Mode5: 17.4–18.2; Mode6: 15.7–16.5; Mode7: 14.2–15.8J/cm²

Manufacturer-stated

Sources differ: Stated fluence does not equal stated irradiance × 10 min for several modes (mode 1: 23.1 mW/cm² → 13.9 J/cm² vs 10.3 stated).

Notes on these figures

Per-mode figures in UK page spec table. Measurement distance, location, instrument, and what the ranges represent (per band? across measurement points?) are NOT disclosed. Not in the manual.

Stated on page as 'Fluence (energy dose) per session'. Several figures do not match the page's own irradiance × 600 s (e.g. mode 1: 23.1 mW/cm² × 600 s = 13.9 J/cm², page says 10.3; mode 4 ranges also differ). Basis not explained — see conflicts.

Light-output figures come from the manufacturer. Independent checks are rare, even in published studies, so treat them as claims. Why

Using it

Treatment

Session length: 10 minutes Conflicting information
Sources differ: Manual regimen: week 4 'max. 20 minutes at a time'. Manual and page: auto-off at 10 min; page FAQ: no more than 10 minutes per session.

Details
Auto-off after 10 min (manual, page). Page FAQ: no more than 10 minutes per session. But manual regimen table says fourth week 'max. 20 minutes at a time'; timer resets when mode is changed.
How often: Build up over 4 weeks to daily use (max once a day); blue modes F2/F6 max 3 sessions per week; once results show, once or twice per week Conflicting information
Sources differ: Manual: ramp-up every 3 / 2 / 2 days then daily; page FAQ: results after 2 weeks with 3–4 sessions a week; efficacy study used daily from day 0.

Details
Manual: wk1 every 3 days, wk2–3 every 2 days, wk4 daily; 'As soon as results show, adjust the frequency to once or twice per week.' Page FAQ: max once a day; first results after about 2 weeks with 3–4 sessions a week.
Modes: 7 modes: F1 red; F2 blue; F3 amber; F4 NIR + deep NIR (invisible; 3 red indicator LEDs light); F5 red + NIR + deep NIR; F6 blue + red + NIR + deep NIR; F7 amber + red + NIR + deep NIR. Default F1; mode button cycles.
Auto shut-off: Yes, after 10 minutes; also switches off on low battery (5 beeps, red flashing)

Design and power

Battery: Lithium, 2,000 mAh, 3.7 V
Details
Sessions per charge not stated.
Charge time: 3 hours
Details
Manual: 'around 3 hours'.
Use while charging: No
Details
'The product cannot be used during charging.'
Eye protection: Removable eye protection covers (page) Conflicting information
Sources differ: Page FAQ recommends removable eye covers; neither manual parts list nor page box list includes them.

Details
Page FAQ: 'We highly recommend using the removable eye protection covers', but use is up to the user and eyes need not be closed. Eye covers are not in the manual's parts list or the page's in-the-box list. Manual: 'Do not look directly at the light source part of the product.'
Weight: 315 g Conflicting information
Sources differ: Manual: 315 g. Product page: 0.32 kg.

Details
Manual: 315 g. Product page: 0.32 kg. Unclear whether either includes the controller.
App needed: No
Details
Operated from buttons on the controller; no app mentioned.

Regulatory status

UK: Advertising Standards Authority ruling (brand-level): Upheld, 5 Nov 2025 (A25-1293796) Independently verified
Details
ASA ruling A25-1293796 (5 Nov 2025), Invention Works BV t/a Silk'n, upheld: a Meta ad and silkn.co.uk page for 'an LED face mask' (model not named) made acne claims; the ASA 'had seen no evidence that the product was registered with the MHRA or had the appropriate conformity marking'. Not confirmed that the ruling concerns this model.
UK: UKCA Not disclosed
Details
No UKCA mark or UK declaration-of-conformity wording found: manual symbol legend (EN p.6) and back cover show the CE mark only; product page mentions no marking. (Contrast: the LED Face Mask 100 manual includes a UK conformity symbol.) Ask.
EU: CE: Manual symbol legend: 'Declaration of Conformity: Products labelled with this symbol meet all applicable provisions of the European Economic Area.' CE mark on back cover. Manufacturer-stated
UK: Intended purpose: 'exclusively designed to help improve your skin's glow, elasticity and texture, and reduce the visibility of wrinkles, fine lines and pigmentation'; private use only Manufacturer-stated
Details
Cosmetic wording; no medical-device classification stated. MHRA registration not checked.
US: FDA 510(k) clearance Not yet checked
Details
openFDA 510(k) searches for applicants Silk'n Beauty / Home Skinovations / Invention Works returned no LED face mask. OEM behind model FAC08 not named, so a clearance under another applicant cannot be ruled out. US status only — not a UK approval.

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.
