Arlington, Virginia - November 07, 2026 - NuYOU360 Ventures LLC today published the complete measurement distribution from a 36-position irradiance scan of its Contour PRO device, releasing output data across the full surface of the mask rather than the single peak figure that is standard practice in the at-home light therapy category.
Irradiance, measured in milliwatts per square centimeter, is the most commonly cited performance specification for light therapy devices and, according to the company, the most commonly misrepresented. A single figure taken at the brightest point of a device, under laboratory conditions, at the surface of the emitter, can be several times higher than the output across the rest of the device or the output that reaches a user's skin during normal use.
The scan NuYOU360 released covers 36 positions across the mask surface at three brightness levels. Across the VCSEL zones, which deliver the device's 665nm, 850nm and 1064nm wavelengths, measured output ranged from 84 to 95 mW/cm² at maximum setting, with a mean of 91.5. Across the LED zones, measured output ranged from 33 to 47 mW/cm². The device is rated up to 100mW/cm² at the VCSEL zone.
The company says the variation across zones is intentional rather than a limitation. Higher-output VCSEL emitters are concentrated along the jawline and the structural perimeter of the mask, where deeper delivery is most relevant, while LED output is distributed more evenly across the mid-face and cheeks. The design reflects a principle the company describes as right dose rather than maximum dose.
"Publishing a distribution instead of a peak means publishing your weaker numbers alongside your strongest," Tzotchevska said. "That is exactly why it is worth doing. A buyer who can see the whole picture can make a real decision. A buyer who sees one number is being asked to trust a stranger."
NuYOU360 is calling on other manufacturers in the category to publish comparable data, arguing that measurement distribution and stated measurement position should become baseline disclosure practice rather than a differentiator. The company published a four-question evaluation standard in October that included measurement position as one of the four criteria consumers should apply to any device.
The Contour PRO, priced at $594, uses 72 quad-chip VCSEL emitters, stated by the company as 288 individual emitters, operating at 460nm, 665nm, 850nm and 1064nm. The device is registered with the FDA, with a 510(k) submission in progress. NuYOU360's RADIANCE, priced at $369, uses 400 LEDs across 415nm, 590nm, 625nm, 830nm and 1072nm, delivers up to 50mW/cm² measured at the worn position, and holds FDA clearance under K242385. The company's entry device at $289 is cleared under the same number.
NuYOU360 was founded in January 2026 by Dora Tzotchevska, who used light therapy devices daily for nearly a decade before starting the company. She has said the decision to publish full measurement data came directly from that experience as a buyer rather than from a marketing strategy.
The complete scan data and an explanation of how to read it are published on the company's website.
