Las Vegas is punishingly dry. The arid winter air means I woke up on Day 3 of CES 2025 with a nosebleed, chapped lips, and ashy legs. This in spite of the fact I slathered myself with two pumps of a fermented bean essence, eye cream, moisturizer, and a lip mask. Staring at my face in the hotel mirror, I wonder if any of those products were doing what they’re supposed to — and if maybe, I should try something different.
This is why I was so eager to try L’Oréal’s Cell BioPrint.
For anyone who’s struggled with their complexion, the Cell BioPrint feels like a holy grail gadget. The device is a mini-lab setup that analyzes a skin sample to generate a report about your skin’s current condition. It’ll also “grade” your skin with regard to oiliness, wrinkles, skin barrier function, pore size, and uneven skin tone. Based on the proteins in your skin, you’ll also see whether you’re more likely to be susceptible to those issues down the line — even if they aren’t issues now. The test also determines whether you’re responsive to retinol, a popular and well-studied skincare ingredient that nevertheless causes a ton of confusion online.
