Conventional LED masks have long struggled with rigid designs that fail to contour closely to the skin, resulting in as much as 90% of light reflecting off the skin from distances as short as 2 cm. This limits the effectiveness of light penetration, preventing sufficient stimulation of deeper skin layers crucial for skin rejuvenation.
Professor Lee's team at KAIST has now introduced a solution: a face-conforming surface lighting micro-LED (FSLED) mask capable of delivering consistent photostimulation to the deeper layers of the skin. This new mask uses a 3D origami design, embedding 3,770 micro-LEDs along with a flexible light-diffusion layer that allows the device to closely hug facial contours, minimizing gaps between the light source and the skin for improved effectiveness.
In clinical trials with 33 participants, the FSLED mask showed a 340% improvement in deep skin elasticity compared to traditional LED masks, demonstrating its capability to reduce wrinkles, sagging, and visible signs of aging.
"The FSLED mask provides cosmetic benefits to the entire facial dermis without the risk of low-temperature burns, making it possible for home-based anti-aging treatments to enhance quality of life," said Professor Keon Jae Lee. The mask will be manufactured by KAIST startup Fronics and will launch globally through Amorepacific's distribution network starting in November.
