This Acne-Fighting LED Mask Is In The Amazon Prime Day Sale
As a beauty journalist, I've had the privilege of testing a myriad of top tier beauty products and learned long ago that a hefty price tag isn't always an indicator of efficacy. Sure putting a £300 tub of luxury cream on my vanity is a flex - and don't get me wrong, some deliver brilliant results - but all too often I'm disappointed. There is one product though, that I am adamant is worth the price tag. I wax lyrical about the FAQ 202 Smart Silicone LED Face Mask, a device that I have been using religiously since it launched in 2023. And it's good news for those who are currently in the market for an LED mask that actually works because this next-level gadget is currently included in the Amazon Prime Day sale. While there are plenty of brilliant beauty deals available on Amazon right now, I consider the sale price of the FAQ 202 Smart Silicone LED Face Mask to be a serious bargain. On an ordinary day, you'd be spending an eye watering £719 not he mask, but thanks to the Amazon Prime Day sale it's now available for £503, that's an impressive30% off. Admittedly £500 is still a lot to spend on a new skincare buy, but think of the FAQ 202 Smart Silicone LED Face Mask as an investment piece. While some are quick to judge the effectiveness of at-home LED treatments in comparison to in-clinic salon-grade technology, the FAQ 202 Smart Silicone LED Face Mask has some impressive claims. It promises to reduce wrinkles by 32%, sebum by 18%, and acne by 48%, all while firming, rejuvenating and repairing the skin. Created by skin tech powerhouse Foreo, the FAQ 202 Smart Silicone LED Face Mask in unlike others on the market which feature only red and/or green and blue light therapy. My go-to boasts seven different wavelengths of LED light and Near Infrared (also known as the ideal wavelength) to penetrate deep beneath the skin's surface to target a range of concerns. For instance, red light combats wrinkles, unevenness, and increases collagen production, while yellow light encourages lymphatic drainage and blue light to targets acne-causing bacteria. As someone who has dealt with acne for over a decade I was keen to see how much different this mask would make to the latter and I'm pleased to report I've seen a noticeable difference. Sameeha Shaikh, beauty writer, says: 'Having used it for the best part of two years, perhaps not as consistently as I'd hoped, I'm now a devotee – so much so, I keep it on my bedside table. While I still get breakouts, the mask has helped to calm the inflammation that comes with acne and helps my skin to heal post-breakout - I feel like it has toned and brightened my skin too. I use the blue, cyan and white light functions to target my problem areas - I love how precise I can be with this. Another win? Comfort levels. It is much more lightweight than other LED masks I have tried out and although it looks bulky in a selfie, it's comparatively slim and feels like a second skin when it's on. And it's wireless, so I can walk around the house and go about my business without being tethered to a plug socket. I've never stuck to an at-home device as religiously as this one, and that is something in itself - I put that down to the ease of use and results - there's no better motivation than good results.' 1. FAQ 202 Smart Silicone LED Face Mask This high tech LED face mask may be costly but its impressive tech and efficacy cushions the blow. Brough to you by skin tech powerhouse Foreo, it is one of the very best at-home LED treatments on the market for good reason. It tackles a host of skin concerns from acne to puffiness and fine lines with its impressive seven different wavelengths of LED light and Near Infrared (NIR).

James Webb telescope reveals 'impossible' auroras on Jupiter that have astronomers scratching their heads
When you buy through links on our articles, Future and its syndication partners may earn a commission. On Christmas Day in 2023, scientists trained the James Webb Space Telescope (JWST) on Jupiter's auroras and captured a dazzling light show. The researchers observed rapidly-changing features in Jupiter's vast auroras using JWST's infrared cameras. The findings could help explain how Jupiter's atmosphere is heated and cooled, according to a study published May 12 in Nature Communications. "What a Christmas present it was — it just blew me away!" study coauthor Jonathan Nichols, a researcher studying auroras at the University of Leicester in the UK, said in a statement. "We wanted to see how quickly the auroras change, expecting them to fade in and out ponderously, perhaps over a quarter of an hour or so. Instead, we observed the whole auroral region fizzing and popping with light, sometimes varying by the second." Auroras form when high-energy charged particles, often released from the sun, slam into gases in a planet's atmosphere, causing the gas to glow. Jupiter's strong magnetic field scoops up charged particles such as electrons from the solar wind — and from eruptions on its highly volcanic moon Io — and sends them hurtling toward the planet's poles, where they put on a spectacle hundreds of times brighter than Earth's Northern Lights. Related: NASA reveals 'glass-smooth lake of cooling lava' on surface of Jupiter's moon Io In the new study, the team looked closely at infrared light emitted by the trihydrogen cation, H3+. This molecule forms in Jupiter's auroras when energetic electrons meet hydrogen in the planet's atmosphere. Its infrared emission sends heat out of Jupiter's atmosphere, but the molecule can also be destroyed by fast-moving electrons. To date, no ground-based telescopes have been sensitive enough to determine exactly how long H3+ sticks around. But by using JWST's Near Infrared Camera, the team observed H3+ emissions that varied more than they expected. They found that H3+ lasts about two and a half minutes in Jupiter's atmosphere before being destroyed. That could help scientists tease out how much of an effect H3+ has on cooling Jupiter's atmosphere.

They also found some puzzling data when they turned the Hubble Space Telescope toward Jupiter at the same time. Hubble captured the ultraviolet light coming from the auroras, while JWST captured infrared light. "Bizarrely, the brightest light observed by Webb had no real counterpart in Hubble's pictures," Nichols said in the statement. "This has left us scratching our heads. In order to cause the combination of brightness seen by both Webb and Hubble, we need to have a combination of high quantities of very low-energy particles hitting the atmosphere, which was previously thought to be impossible. We still don't understand how this happens." In future work, the researchers plan to study the source of this unexpected pattern using additional JWST data as well as observations from NASA's Juno spacecraft, which has been observing Jupiter from orbit since 2016.

NASA's Webb Space Telescope reveals ancient surface of Pluto and other celestial bodies for the first time
Scientists at NASA for the first time have been able to observe the make up of Pluto and other small and icy celestial bodies in the outer solar system. They had expected to find that the surfaces of the bodies, known as 'trans-Neptunian' objects, were dominated by frozen molecules that are gases or liquids on the surface of Earth, like water, methane, and carbon dioxide. They believed that radiation from the sun and solar system would alter that chemistry, creating new and more complex hydrocarbon molecules like methanol and ethane. New data from the James Webb Space Telescope's Near Infrared Spectrograph instrument (NIRSpec) has 'confirmed this, but in unexpected ways, and in unprecedented detail,' NASA explained in a blog post on Wednesday. The findings were published in the journal Nature Astronomy. To reach these conclusions, the researchers used data from NIRSpec, one of four science instruments on the Webb telescope. Spectrographs scatter light from an object into a spectrum: a chart or a graph that shows the intensity of light being emitted over a range of energies. Analyzing that chart can reveal an object's temperature, mass, and chemical composition. With the data from NIRSpec – which detects near-infrared wavelengths of light and is capable of observing more than 100 bodies at once – the scientists were able to study more than 75 trans-Neptunian objects. The objects range in size, with diameters less than tens of miles to 1,500-mile-diameter dwarf planets. The objects travel on orbits comparable in size or even larger than Neptune's orbit. NASA says their paths reflect the migration of the ice giants Uranus and Neptune during the early formation of the solar system. Data from nearly 60 trans-Neptunian objects helped to identify three 'spectral classes' characterizing the spectra they analyzed. Spectral classes are how astronomers categorize stars based on their light spectrum and temperature. The three categories are distinct in their color and shape. Notably, they are generated by molecules that contain water and feature carbon dioxide ice, and silicate-rich dust. Those that were shaped like bowls formed closer to the sun and were subject to higher temperatures, the space agency said. The data came from the DiSCo-TNOs program, which is comprised of a group of international researchers. Looking forward, researchers will work on imaging and spectroscopy of a handful of these objects and their satellites.
