New sensor from L’Oréal tracks UV exposure to keep your skin safe from the sun

It’s no secret that too much exposure to ultraviolet light can do serious damage to your skin — and even cause skin cancer. To help reduce such exposure, personal care company L’Oréal has announced a small wearable sensor, called the La Roche-Posay My Skin Track UV sensor, that’s aimed at tracking your exposure to UV light, which could seriously help users improve the health of their skin.

There are a number of things that make this sensor highly useful. For starters, the sensor was built with Apple users in mind — it integrates with Apple’s HealthKit, meaning you can track how much UV light you’re exposed to straight from the Apple Health app. On top of that, it uses NFC to connect to your iPhone — not Bluetooth. What that means is that it doesn’t have a battery that needs to be charged. L’Oréal also has an accompanying app for the device, which can give you tips on how to keep your UV light exposure at a healthy level.

This isn’t the first time L’Oréal has shown off its UV-tracking tech. The sensor was developed by L’Oréal’s Technology Incubator, which introduced a prototype of the device, called the UV Sense, last year. The UV Sense attached the to the wearer’s fingernail instead of clipping to a shirt as the new sensor does. Before that, it first showed off the tech as a device that can attach to your skin.

The sensor itself actually measures UVA radiation, which is a type of radiation that penetrates deep into your skin and can cause aging and wrinkling. As a report from Wired notes, however, the sensor can use the information about UVA radiation to track UVB exposure too. Both UVA and UVB exposure are thought to contribute to skin cancer, but UVB seems to have a bigger impact, as it also causes your skin to burn.

The sensor itself costs $59.95 and is available in the U.S. exclusively at Apple stores or on the Apple website. Thankfully, Android users don’t need to miss out — while the device is being sold through Apple, it still works with an Android device through the accompanying Android app, though you won’t be able to integrate the collected data with Apple’s HealthKit.

Cost-cutting strips Pixel 9a of the best Gemini AI features in Pixel 9

The Pixel 9a has been officially revealed, and while it's an eye candy, there are some visible cutbacks over the more premium Pixel 9 and 9 Pro series phones. The other cutbacks we don't see include lower RAM than the Pixel 9 phones, which can limit the new mid-ranger's ability to run AI applications, despite running the same Tensor G4 chipset.

Google's decision to limit the RAM to 8GB, compared to the 12GB on the more premium Pixel 9 phones, sacrifices its ability to run certain AI tasks locally. ArsTechnica has reported that as a result of the cost-cutting, Pixel 9a runs an "extra extra small" or XXS variant -- instead of the "extra small" variant on Pixel 9 -- of the Gemini Nano 1.0 model that drives on-device AI functions.
