KAIST team develops flexible LED mask with 340 percent increase in deep skin elasticity
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 solu
