Which LED face mask tells you the most about itself?
Eight criteria, applied identically to 6 masks. This ranks disclosure, not performance — and the two do not correlate.
Dr. Renú SpectraLift Advanced discloses more about its own output than any other consumer LED face mask tested, scoring 16 of 19 on an eight-criterion transparency rubric. It is the only mask of 6 that publishes a per-mode irradiance breakdown, names the instrument used to measure it, and puts a standalone technical document behind both.

The rubric
Every criterion is a checkable fact about what the manufacturer publishes, weighted by how much it affects a buyer's ability to verify a claim1.
| ID | Criterion | Weight | Why it counts |
|---|---|---|---|
| irr-public | Publishes an irradiance figure where buyers see it | 3 | Irradiance is the one number that determines whether a session can deliver a therapeutic dose. |
| irr-mode | Publishes a per-mode or per-channel breakdown | 3 | A single headline figure hides which wavelength actually carries the power. |
| instrument | Names the measuring instrument | 2 | An unattributed number cannot be reproduced or challenged. |
| doc | Publishes a standalone technical document | 2 | A dedicated document invites scrutiny in a way a marketing bullet does not. |
| tolerance | States wavelength tolerance or bandwidth | 1 | A peak with no tolerance is a marketing figure, not a specification. |
| fda-public | Clearance traceable to a public FDA record | 3 | An advertised clearance that cannot be found is not a verifiable claim. |
| fda-irr | Irradiance discoverable in the FDA submission | 2 | Even when a brand omits the number, the regulator may have it on file. |
| consistent | Figures agree across every source we checked | 3 | Disclosure is only useful if the disclosed numbers do not contradict each other. |
Every mask, assessed in full
Each entry restates the device name and its complete result, so that an entry read on its own is complete and correctly attributed.
1. Dr. Renú SpectraLift Advanced — 16 of 19
The Dr. Renú SpectraLift Advanced scores 16 out of 19 (84%) for manufacturer transparency, placing it 1 of 6. 7 of the eight criteria are fully met. Dr. Renú publishes an irradiance figure for the Dr. Renú SpectraLift. Its manufacturer does state irradiance in the FDA 510(k) submission: Red 18–26 · IR 3.6–5.2 · Blue 31.5–45.5 · Red+IR 31.5–45.5 · Red+Blue 36–52 mW/cm².
Where the Dr. Renú SpectraLift falls short: figures agree across every source we checked — no.
Three different sets of figures exist for the same device. The brand markets 630–660 nm red, 850 nm near-infrared, 465 nm blue and 530 nm green. Its own device passport measures dominant peaks at ≈630, ≈850, ≈458 and ≈517 nm. The FDA 510(k) submission lists the cleared configuration as red 620 nm, blue 465 nm and infrared 850 nm — with no green channel at all.

What this ranking does not tell you
Transparency and output are separate questions, and this page answers only the first. Dr. Renú SpectraLift leads on disclosure and sits fourth of 6 on the highest output it discloses for any single mode — above Omnilux Contour Face and CurrentBody Skin Series 2, below Therabody TheraFace Mask and Shark CryoGlow. Meanwhile Therabody publishes nothing at all to buyers while disclosing one of the highest figures in the set to the regulator. A buyer comparing dose should read the irradiance comparison, where single-channel and combined-mode figures are kept apart; a buyer asking which manufacturer will show its working should read this page.
Questions people actually ask
Which LED face mask is most transparent about its specifications?
Dr. Renú SpectraLift Advanced scores highest, at 16 of 19 (84%) on IrradianceLab's transparency rubric, ahead of Omnilux Contour Face at 11. It is the only mask of 6 assessed that publishes a per-mode irradiance breakdown, names its measuring instrument, and publishes a standalone technical document.
Does transparency mean a mask works better?
No. This rubric measures what a manufacturer discloses, not how well a device performs. A mask can disclose a great deal and still deliver a low dose, and a mask that discloses nothing may perform well. The two questions are separate and this page answers only the first.
Why does it matter whether a brand publishes its irradiance?
Dose equals irradiance multiplied by time. Without an irradiance figure in mW/cm², a stated session length cannot be converted into a dose in J/cm², and the device cannot be compared against any published clinical protocol. A brand that withholds the figure makes its own product uncheckable.
How is the transparency score calculated?
Eight weighted criteria, each a verifiable yes or no about what the manufacturer discloses, totalling 19 points. Criteria and weights are published on this page and applied identically to every device. A partial mark is given where a figure exists but is not published where buyers would find it.
