Light output (irradiance)

Not disclosed

Dose per session

Not published

Not yet checked

Notes on these figures

No irradiance given. Manual gives energy per 4-minute setting instead: red 12–14 J/cm²; red + IR setting red 12–14 J/cm² and infrared 9–11 J/cm²; blue 10–12 J/cm², described as 'generated across the entire device'. Measurement distance, method and whether skin-surface dose are NOT stated. Not converted to irradiance here.

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: 12 minutes
Sources differ: Brand says '12 minutes a day'; its comparison chart and the Guardian say 4–12 min (single light type = 4 min).

Details
Pre-set 12-minute cycle = 4 min each of red, red + IR, blue. Pressing the LED button skips to the next light type, so a session can be shorter. Brand comparison chart says '4-12 minutes'. Vibration-only mode runs 12 min.
How often: Once a day, 6 days per week
Details
Manual: 'Recommended Use: 6 days per week'. Product page: '12 minutes a day', study 'Monday–Saturday'. No course length stated (study ran 12 weeks; claims say results 'in as little as 8 weeks').
Modes: Automatic 12-min cycle (red → red + IR → blue) or a single light type via the LED button; vibration on/off with 3 modes (Relax, Refresh, Relieve); vibration-only mode
Auto shut-off: Yes, when the 12-minute treatment ends

Design and power

Power: Built-in rechargeable battery, USB-C; cordless in use. Brand says use a USB-C adapter of at least 20 W (adapter not included)
Battery: Lithium polymer, 1200 mAh, 23 g; about 60 minutes of use (12-minute routine with vibration)
Details
Manual battery info is headed 'Device Battery Information - EU'. Elsewhere manual calls it a lithium-ion battery.
Charge time: — Not disclosed
Use while charging: No
Details
'Do not try to use the device while charging.'
Eye protection: Built-in silicone eye shield (manual: 'pre-installed eyeshield (assembled)'; UK page: 'removable protective eye shield')
Details
Manual warns the eye shields may cause redness around the eyes that should fade within 5–10 minutes.
Weight: 514 g
Details
Dimensions 200 × 220 × 120 mm. Cordless, so no separate controller.
App needed: No
Details
Two buttons on the device; no app mentioned in manual or on UK page.
Subscription: No
Details
No app or paid features mentioned.
Replaceable battery: No

Context
Comparative claim; basis for 'largest' not given.

“87% of study participants reported their skin looks and feels smoother”
Context
Perception survey; page footnote says participants were compensated.

“Firms skin, enhances facial contour and helps reduce the appearance of sagging, loose skin”

“Improves skin tone evenness and texture”

“Blue light therapy (415 nm wavelength) fights blemish-causing bacteria and helps prevent new bacteria from growing.”

“Red and infrared LED light therapy (633, 830 nm wavelength) boosts your skin's natural collagen production”

“Blue Light is intended to treat mild to moderate inflammatory acne”
Context
US 510(k)-style indication; also in the international manual.

“The device is safe for use on all skin types (Fitzpatrick Types 1 - 6).”

Evidence

The clinical findings behind TheraFace Mask Glo (Therabody blog) / ClinicalTrials.gov NCT07054710

Manufacturer-stated

Studied: This exact mask Not peer-reviewed

Single-group, open-label (no masking), before-vs-after; no control or sham group · 115 enrolled, 104 completed participants

What it measured and its limits

Measured: Expert grading, VISIA-CR imaging, Cutometer and self-assessment. Brand reports group changes at 12 weeks e.g. radiance +25.4%, texture +22.9%, firmness (Cutometer) +14.3%, fine lines 4.0%, undereye wrinkles −3.1%; wrinkle depth not significant at group level

No control or sham group, so changes can't be separated from placebo, season or skincare changes
Sponsor-funded; summary written by Therabody staff; no full report or registry results published
Only one primary outcome registered (overall skin appearance); many outcomes reported, with some small effects
Mostly women
Light and vibration were used together, so effects can't be attributed to light alone
Registry summary gives age 39–64 but eligibility 35–65

TheraFace Mask 12-week clinical study (Therabody blog, 2023)

Manufacturer-stated

Studied: An earlier model Not peer-reviewed

Single-group ('monadic') before-vs-after; no control or blinding described · 36 enrolled, 31 completed participants

What it measured and its limits

Studies the original TheraFace Mask (648 LEDs, different design), not the Mask Glo — don't use for Glo claims

Listed only so it isn't mistaken for Glo evidence; Therabody's Glo study page links to it.

About this review

Fortune score 4/5. Lists irradiance as '<300 mW/cm² for red/NIR, <100 mW/cm² for blue', which reads as an upper limit, not a measurement; Therabody doesn't publish a figure. Cites a 12-week, 104-person study (brand data, not seen by us). Price quoted $379.99. US buying guide by Christina Snyder; individual testers over several weeks, testing described as ongoing; 'Fortune score' out of 5. Article carries an affiliate disclosure; prices in US dollars.

Regulatory status

UK: UKCA: Manual symbol table lists 'UKCA Mark for UK' on the rating label Manufacturer-stated
Details
Table text is garbled ('On rating label (Only in the EU)' sits next to it). UK product page says nothing about UKCA/CE. Ask for the UK declaration of conformity and which regulations it covers.
EU: CE / EMC: Manual lists a mark 'in accordance with Directive 2014/30/EU Electromagnetic Compatibility'; international edition says to scan a QR code for the Declaration of Conformity under Regulation (EU) 2019/1020 Manufacturer-stated
Details
Only the EMC Directive is named; no medical-device or cosmetic-device regulation cited.
US: FDA 510(k) clearance: Manual: 'FDA-Cleared, Class 2 Medical Device, K230293' Conflicting information
Details
FDA database: K230293 is 'TheraFace Mask' (the original, sibling device), Therabody Inc., cleared 2023-06-09, product code OHS. No separate 510(k) for 'Mask Glo' found under applicant Therabody (openFDA search, 1 Nov 2026). Whether the Glo is covered by K230293 is not confirmed. US status only — not a UK approval. UK page makes no FDA claim.
UK: MHRA device registration Not yet checked
Details
Manual gives medical-sounding indications (wrinkles, 'mild to moderate inflammatory acne') but also says 'not intended to diagnose, mitigate, or treat diseases'. Classification needs further review. 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.

Safety standards declared (7)

IEC 60601-1, IEC 60601-1-2:2014, IEC 60601-1-11 (written 'IEC60601-11' in manual), CISPR 11 (Group 1, Class B), IEC 61000-3-2, IEC 61000-3-3, IP22

Declared in manual; test reports not published. IEC 60601-2-57 and IEC 62471 (photobiological safety) not listed — ask. Manual says 'Class III equipment with type BF applied part' (electrical safety class, not a medical-device class).

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.

Open questions (13)

Facts we still need from Therabody

Irradiance (mW/cm²) per band, with measurement distance, points measured and instrument; how the J/cm² figures 'across the entire device' were measured
LED count per band (red / IR / blue) and how the 504 LEDs relate to the '168 light points' the Guardian reports
Wavelength tolerances (±nm), peak vs dominant; why wavelengths are not in the manual
Is the Mask Glo covered by 510(k) K230293 (cleared for the original TheraFace Mask), or does it have its own clearance?
UK declaration of conformity: which regulations does the UKCA marking cover? Is the product registered with MHRA?
IEC 62471 photobiological safety classification and IEC 60601-2-57 conformity
Full report of the 12-week Eurofins CRL study (NCT07054710) and whether results will be posted on ClinicalTrials.gov
Basis for 'largest clinical study of any LED mask on the market'
Is there a UK-specific manual? Only the US PDF is linked
