Most LED masks are sold on a number the seller has never checked.
A factory quotes a wavelength — 630 nanometres, 850 nanometres — and that number goes on the box, into the advertising, and onto the product page. Almost nobody measures what the finished device actually emits at the distance it sits from your face. Where independent testing has been done in this category, the gap between the advertised figure and the measured one has been large enough to become the subject of litigation.
Our mission
To build the one brand in this category whose numbers you can check.
Not the boldest claim, the loudest launch or the deepest discount. The one where every figure on the page is a figure we measured ourselves and will stand behind. That is a harder promise to make than clinically proven, and a great deal harder to fake.
What that means in practice
The wavelength is the easy part. The variable that decides whether a device does anything at all is dose — intensity multiplied by time. So we publish the measured output of every mode: peak wavelength, irradiance in milliwatts per square centimetre at skin distance, and total dose in joules per ten-minute session. Taken with a spectroradiometer, not copied from a specification sheet. The report ships in the box alongside the device.
That is a fact about the hardware, not a promise about your face. The distinction matters, and it is why you will not find before-and-after photographs here, or a claim that this device treats anything. Light therapy is slow, cumulative and modest. Anyone telling you otherwise is selling harder than the evidence allows.
What you actually get
A measured device at $119.99, when comparable masks from established brands sell for three to four times that — because you are paying for the hardware rather than a decade of somebody else's advertising.
Ten minutes a session, hands free and cordless. A one-year warranty on the device and the controller. And sixty nights to decide, with the return postage paid — because a device you are meant to judge at eight weeks has no business coming with a thirty-day window.
