3 Dermatologists Tell Us What They Really Think About Smart Beauty Products

Predictable, consistently clear skin is priceless — but getting there can sometimes feel like a game of guess and check. It’s hard to know if that moisturizer you religiously apply is actually working, or if your go-to SPF is truly effective, but smart beauty devices can help you connect the dots. Blending innovative technology with real-time data, these mini-but-mighty products can help us refine our regimens, allowing us to confidently go makeup-free. But are they too good to be true? Read on to learn three experts’ opinions on these devices and whether they’re worth using.
La Roche-Posay
H20+ Beauty MiLi Skin Moisture Meter
The small size of this portable device, which was “inspired by the tracking capabilities of wearable fitness technology,” according to H20+ Beauty CEO Joy Chen, makes it easy to toss in your purse (which is helpful if you’re traveling to an extra dry climate). The portability also lends itself well to using it on other parts of your body — don’t forget that your neck, hands, and chest need to be properly hydrated too! After applying moisturizer anywhere, you can see just how much your hydration levels rise and if additional products are needed by touching the tracker to your skin for five seconds. The data is then shown in the connected MiLi Pure app. It’s an easy way to make sure your face is properly plumped-up. The question still remains whether or not it effectively charts long-term issues.
3. FOREO UFO ($199): Pressed for time but still want to give yourself a spa-quality facial? Meet your new bathroom BFF. This palm-sized device, which well surpassed its Kickstarter goal, claims to give you the benefits of a 20-minute treatment in just 90 seconds. “The UFO is great for amping up your facial mask game,” says New York City-based dermatologist Michele Farber. “It cools, heats, massages, and helps your mask work more effectively.” The game-changing detail about this tech-enabled mask is that it combines multiple mask benefits in one thanks to its various settings, which are controlled via an app on your phone.
