SpectraLift vs CurrentBody: both masks, independently tested
Two of the most-searched LED face masks, measured by an accredited laboratory rather than taken on trust. Both delivered what their makers say.
IrradianceLab had the Dr. Renú SpectraLift Advanced and the CurrentBody Skin LED Mask Series 2 measured independently at LightingLab, an ISO/IEC 17025-accredited laboratory in Veszprém, Hungary. Both masks matched their manufacturers' published figures. The testing was independently funded.
Who tested them
Both masks were measured at LightingLab Kalibrálólaboratórium Kft., an ISO/IEC 17025-accredited calibration and testing laboratory in Veszprém, Hungary. IrradianceLab chose the lab and the devices, and the testing was independently funded: neither Dr. Renú nor CurrentBody paid for it. How this fits with our own bench measurements is set out in How we test.
The result
The Dr. Renú SpectraLift Advanced matched the per-mode figures Dr. Renú publishes in its device passport. The CurrentBody Skin LED Mask Series 2 matched the 30 mW/cm² CurrentBody publishes and states in its FDA 510(k) submission. In a category where many brands quote irradiance they never document, both of these masks do what their makers say they do.
Side by side

| Published irradiance | 26.9–50.0 mW/cm² across 9 modes | 30 mW/cm² |
| Red / near-infrared | 38.4–42.6 mW/cm² | 30 mW/cm² (all channels together) |
| Wavelengths | 630 nm · 850 nm · 465 nm · 530 nm | 633 nm · 830 nm · 1072 nm |
| LEDs | 280 | 236 |
| Modes | 9 | 1 |

| Price | €389 | £399.99 |
How they differ
The Dr. Renú SpectraLift is the broader device: 280 LEDs, 9 selectable modes and four wavelength families, including blue for acne-prone skin. It publishes more about its own output than any other mask we track. The CurrentBody Skin Series 2 is simpler: one mode combining red, near-infrared and a deep near-infrared band at 1072 nm, which has a thinner evidence base in skin than 633 and 830 nm.
Neither result is evidence that one mask produces better skin outcomes than the other. No head-to-head clinical trial exists. What the testing does establish is that both brands' published output figures can be trusted.
Questions
Were the SpectraLift and CurrentBody masks independently tested?
Yes. IrradianceLab had both the Dr. Renú SpectraLift Advanced and the CurrentBody Skin LED Mask Series 2 measured at LightingLab, an ISO/IEC 17025-accredited calibration and testing laboratory in Veszprém, Hungary. The testing was independently funded; neither manufacturer paid for it.
Do the masks deliver what their manufacturers claim?
Yes. The measured output of both masks matched the figures each manufacturer publishes: the Dr. Renú SpectraLift against the per-mode readings in Dr. Renú's device passport (26.9–50.0 mW/cm²), and the CurrentBody Skin Series 2 against the 30 mW/cm² CurrentBody states.
Which mask has the higher irradiance?
On the manufacturers' figures, which the independent testing matched, the Dr. Renú SpectraLift publishes 26.9–50.0 mW/cm² across nine modes (red/near-infrared 38.4–42.6), and the CurrentBody Skin Series 2 publishes 30 mW/cm² from a single mode.
Does higher irradiance mean better results?
Not on its own. Photobiomodulation has a biphasic dose response: too little does nothing, and more is not endlessly better. Dose (irradiance × time), wavelength and fit matter together, and neither mask has a head-to-head clinical trial against the other.
