Notes on these figures

FAQ: '18 joules/cm2 in a 10 minute treatment, which equates to 30 milliwatts/cm2 of Near-Infrared 830nm and Red 633nm.' Measurement distance, location, instrument and per-band vs combined are NOT disclosed. K191629 summary gives '30mw/cm2 total' for faceLITE.

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
How often: 3–5 times per week; minimum programme 4–6 weeks
Details
FAQ also says 'The Boost has been designed for daily use.' K191629 protocol for faceLITE: 5× weekly for 6 weeks.

Details
Page says wavelengths are 'delivered simultaneously'; no other modes mentioned. Controller interface not described (manual not available).
Auto shut-off: Yes, at end of the 10-minute treatment

Details
'The Boost will NOT work if plugged into a wall socket.'

Details
UK brand page: 'Tested to international eye-safety standards' — no goggles or shield mentioned. US retailer Dermstore says an eye shield is provided as an option. Ask whether UK units include eye shields.

Evidence

A study to determine the efficacy of combination LED light therapy (633 nm and 830 nm) in facial skin rejuvenation (Russell, Kellett, Reilly; J Cosmet Laser Ther 2005;7(3-4):196-200)

Source read by Luma Index (results not verified)

Studied: Similar light settings

Clinical trial; no control group, randomisation or blinding stated in abstract · 31 participants

What it measured and its limits

Measured: Profilometry changes significant at week 12; 52% showed 25–50% improvement in photoageing scores; 81% self-reported periorbital improvement

Used the Omnilux LED system, not the Boost
Same wavelengths but much higher fluence per session
No control group stated; small sample
Abstract only read

Listed twice on the brand's Clinical Studies page.

A prospective, randomized, placebo-controlled, double-blinded, split-face clinical study on LED phototherapy for skin rejuvenation (Lee SY et al.; J Photochem Photobiol B 2007;88(1):51-67)

Source read by Luma Index (results not verified)

Studied: Similar light settings

Randomised, sham-controlled, double-blinded, split-face trial; four arms (830 nm, 633 nm, 830+633 nm, sham) · 76 participants

What it measured and its limits

Measured: Wrinkle reduction up to 36% and elasticity up to 19% vs baseline in active arms; histological increase in collagen and elastic fibres; no adverse effects reported

Not the Boost device (unnamed LED devices)
Treatment frequency (2×/week) differs from Boost instructions
Abstract only read

Other studies on brand's Clinical Studies page (Bhat 2005 Omnilux Revive; Baez 2007; plus 'wellbeing' papers on exercise, pain, blood pressure, melatonin, sleep, migraine)

Not yet checked

Studied: General red light research

What it measured and its limits

None tested the Boost. Several involve lasers or unrelated light exposure. One link on the page is mismatched (Zhu 'Circadian Rhythm Sleep Disorders' title links to the Morita study). No study of the Boost itself is published.

General research on red light doesn't prove a particular mask gives the same results. Research overview

Regulatory status

UK: UKCA Not disclosed
Details
No UKCA or CE wording on any brand page read. Manual not available to check labelling.
US: FDA 510(k) clearance: K191629 Conflicting information
Details
Brand FAQ: 'FDA-Cleared Medical Device with over-the-counter clearance … 510(K) No. K191629'. The FDA record for K191629 is for 'faceLITE LED mask', applicant iSMART Marketing Svcs Ltd (Sutton Coldfield, UK), cleared 12 Sep 2019, product code OHS, OTC, 'treatment of full-face wrinkles'. Device name and applicant do not match The Light Salon/Boost. Parameters are similar (630/830 nm, 30 mW/cm², 600 s). Possibly an OEM clearance — ask. US status only, not a UK approval.
UK: MHRA device registration Not yet checked
Details
Brand describes it as an 'FDA-Cleared Medical Device' with a wrinkle-treatment claim; UK classification not stated. 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.

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 The Light Salon

Legal entity selling the Boost in the UK (name, registered address, company number) — The Light Salon Limited (09298920) or The Light Salon Boost Limited (11477110)?
Is the Boost the same device as the FDA-cleared 'faceLITE' (K191629, iSMART Marketing Svcs)? Who is the manufacturer?
UKCA / CE marking and declaration of conformity; MHRA registration status
LED count: 56 dual-chip (56 positions) or 112 emitters? Why do some retailers say 57?
Energy dose 18 or 19.2 J/cm²? Irradiance measurement method (distance, points, instrument, per band or combined)
Wavelength tolerances (±nm); 633 vs 630 nm
Safety standards tested to (IEC 60601-2-57, IEC 62471 risk group?)
User manual PDF download (Glamour UK says a printed manual comes in the box; none is published online)
Weight, charge time, sessions per charge, whether the battery is replaceable
Has the controller changed? Liberty's product photo shows a rounded black controller; other retailers show a stick-shaped power bank.
Are eye shields included with UK units? (Glamour UK's 2024 review lists eyewear in the box.)
Any study of the Boost device itself
Authorised UK retailers list
