Dealing With Heat Damage? L’Oréal Debuts Near-Infrared Light Hair Tool That Styles Below 320 Degrees
From hair tools to laptop clips, near-infrared light is showing up everywhere after CES 2026
Near-infrared light has been quietly powering at-home red light therapy devices for years, but CES 2026 changed the conversation completely. In January, the same wavelength showed up inside a hair straightener, a paper-thin face mask you wear for 10 minutes, and a webcam-sized clip that delivers light therapy while you sit at your laptop.
The pitch from every company on the show floor was the same: NIR doesn’t have to be a scheduled wellness session anymore. It can fit into what you’re already doing. Here’s what actually launched, what the science supports, and what you can realistically expect.
What near-infrared light actually is
Near-infrared light sits just past the visible red portion of the light spectrum. It penetrates deeper into the skin and hair than visible light and is the same core mechanism behind the at-home red light therapy panels that have surged in popularity for skin tone, fine lines, and hair support over the past several years. What shifted at CES 2026 isn’t the science. It’s where the technology is showing up.
Instead of a dedicated panel you stand in front of, NIR is now being built into everyday objects. That changes who uses it, how often, and for how long, which matters because consistency is the biggest factor in whether light therapy produces visible results.
L’Oréal’s new hair tool that styles with light instead of heat
L’Oréal’s Light Straight + Multi-styler was named a CES 2026 Innovation Award Honoree. It uses patented near-infrared light to reshape the internal hydrogen bonds of each hair strand at under 320 degrees Fahrenheit. That matters because conventional flat irons regularly hit 400 degrees and above, the point at which keratin starts to break down.
L’Oréal’s own consumer research found that 58 percent of women surveyed linked heat to their hair damage. Company instrumental testing showed the device works three times faster and leaves hair twice as smooth compared to premium competitors. Those numbers are self-reported and haven’t been independently verified, which is worth keeping in mind. R&D wraps at the end of 2027, and no price or launch date has been announced yet.
L’Oréal’s flexible LED face mask that fits like a sheet mask
The second L’Oréal device to earn a CES 2026 Innovation Award is an ultra-thin LED face mask, currently in prototype form. It’s one millimeter thick, made of flexible silicone, and developed with iSMART Developments, a specialist in LED device innovation. The mask delivers red light at 630 nanometers and near-infrared light at 830 nanometers through an integrated skin-safe microcircuit. Sessions are ten minutes, designed for daily use, and target fine lines, sagging, and uneven tone. L’Oréal is targeting a global 2027 launch at a price described as below the highest-end LED masks currently on the market, though a specific figure hasn’t been confirmed.
The laptop clip that delivers NIR while you work
Sunbooster, from SunLED Life Science, is the most immediately available device from CES 2026’s NIR lineup. It clips to a laptop, monitor, or tablet and projects near-infrared light while you work, designed for two to four hours of passive daily use. The pitch is indoor daylight deficiency: the idea that most of us aren’t getting enough natural sunlight exposure during a standard workday, and that NIR can partially address the energy, mood, and skin effects of that deficit. It tracks your daily dosage and is priced at approximately $235.
The company references human and laboratory studies from the University of Groningen and Maastricht University, though the full studies aren’t publicly linked. A phone case and NIR-enabled monitor are in development. Coverage comes from CyberGuy’s CES 2026 roundup and TechRadar’s hands-on report.
What’s been proven and what’s still a promise
Near-infrared light therapy has a real research foundation. The wavelengths used across all three CES devices, 630 to 850 nanometers, fall within the range most studied in clinical photobiomodulation research for skin, hair, and cellular health. What doesn’t yet exist is independent verification of these specific products’ performance claims.
L’Oréal’s numbers come from its own labs. Sunbooster’s university citations aren’t directly accessible. That doesn’t mean the devices won’t work. It means they’re products to evaluate carefully when they reach market, not ones with a fully published track record yet.
When these devices will be available and what to do in the meantime
Sunbooster is available now at roughly $235. L’Oréal’s LED face mask and Light Straight styler are both targeting 2027 launches with pricing still to be announced. If you don’t want to wait, at-home red light therapy panels and masks from established brands are already widely available and use the same core wavelengths.
CES 2026 introduced a new way to deliver NIR, not new science behind it. The at-home devices already on the market remain the most accessible way to start building consistent NIR use into your routine right now.
