A research team at KAIST, led by Professor Keon Jae Lee, has developed an innovative deep skin-stimulating LED mask that has shown remarkable results in clinical trials, enhancing dermis elasticity by 340%. Unlike conventional LED masks that struggle to adhere to the contours of the face, causing light reflection and reduced efficacy, the new face-conforming surface lighting micro-LED (FSLED) mask uses a 3D origami structure to deliver uniform photostimulation to deeper skin layers. Clinical trials with 33 participants demonstrated significant improvements in reducing wrinkles, sagging, and signs of aging. Professor Lee emphasized the mask’s benefits as a safe, at-home anti-aging treatment without the risk of low-temperature burns. The product, manufactured by Fronics—a KAIST startup—will be available globally through Amorepacific starting in November. The findings were published in the journal Advanced Materials on October 22, 2024, with contributions from KAIST students Min Seo Kim and Jaehun An.
