Light output (irradiance)
30mW/cm²
Measured: UK IFU 'Max. output optical power density': 30 mW/cm² Revitalise (red + NIR); 34 mW/cm² Energise (red + blue). US 510(k)/US IFU: Revitalise 30 (red 18 + NIR 12); Energise 42 (blue 26 + red 16). Conflicting information
Dose per session
18J/cm²
Manufacturer-stated
Sources differ: Energise setting maximum: 34 mW/cm² (UK IFU) vs 42 mW/cm² (US 510(k) and US IFU). Revitalise 30 mW/cm² in all.
Revitalise figure agrees across sources; Energise differs (34 UK vs 42 US). Stated as maximum; measurement distance, points measured and instrument NOT disclosed.
Revitalise: 510(k) states red 10.8 + NIR 7.2 J/cm² per 10-min session. Energise: blue 15.6 + red 9.6 = 25.2 J/cm² (510(k)). Using the UK IFU's 34 mW/cm² for Energise would give 20.4 J/cm² (Luma Index calculation, 34 × 600 s ÷ 1000) — not stated by Lustre.
Light-output figures come from the manufacturer. Independent checks are rare, even in published studies, so treat them as claims. Why
Sources differ: UK IFU: Energise 4×/week, Revitalise 5×/week, both for 6 weeks. Product page: '10 minutes daily'.
UK IFU (and 510(k)) give 4× and 5× weekly for 6 weeks. Product page says '10 minutes daily' / '10 min per session, daily'.
Sources differ: 2023 510(k) describes a one-button device and does not mention app/Bluetooth; UK IFU (Dec 2024) and product page describe app control of four zones. Unclear whether the hardware was revised.
Product page calls the settings 'Revitalise Mode' and 'acne mode'. The 2023 510(k) describes one button and two modes but does not mention the app/Bluetooth.
IFU: 5 V 1 A supply. 510(k) lists an adapter (100–240 V in, 5 V 1 A out) in its comparison table but not in its box contents.
UK IFU gives 'Lithium-ion' only; capacity from 510(k) and US IFU. Sessions per charge not stated.
'the mask will not work while being charged.'
Sources differ: UK IFU: built-in eye protection. 2023 510(k): removable eye protection.
UK IFU lists 'Built-in Eye Protection'; 510(k) (2023) lists 'Removable Eye Protection'. Guardian tester reports the eye protectors do not shield well.
'Weight of the device'. Dimensions 165.90 × 198.24 × 108.22 mm.
Settings run from the button; app (iOS/Android, Bluetooth) needed for zone personalisation and requires creating an account.
No paid app features mentioned; app requires an account.
UK IFU: 'The mask contains no serviceable parts.' US IFU: battery 'is not removable by the user'.
Values are as stated by Lustre unless marked otherwise.

From the US 510(k) and US IFU (US IFU states 'IEC 62471:2006 Risk Group 1'). The UK IFU lists no standards. Test reports not published. 510(k) biocompatibility relies on identical materials to another device (K2217752 as printed), not new testing.
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.
