Researchers have unveiled a new AI system that can predict how old you are simply by looking at a photo of part of your face. And, in what may not come as much of a surprise to many, the experts say the corners of your eyes are the biggest giveaway. The new technique tested on more than 8,000 photos could pave the way for more precise age estimations even when just a small portion of the face is visible, and lead to more personalized skin care treatments. According to the researchers from Haut.AI, the skin near the corners of the eye, and the general eyelid area, were the most effective in predicting age. In a new study, researchers from AI skin care firm Haut.AI used 8,414 anonymized high-resolution images to test the accuracy of their system.
