A team of researchers has created an innovative LED mask designed to stimulate the deeper layers of the skin, and clinical trials have confirmed that it can enhance dermis elasticity by an impressive 340%.
A KAIST research team led by Professor Keon Jae Lee has developed a deep skin-stimulating LED mask which has been verified in clinical trials to improve dermis elasticity by 340.
Traditional LED masks often lack flexibility in their design, which prevents them from fitting snugly to facial contours. This results in significant light reflection, with as much as 90% reflected away when positioned 2 cm from the skin, thus limiting light absorption and reducing the stimulation of deeper skin layers that are crucial for effective rejuvenation.
To overcome these issues, Professor Lee’s team created a face-adapting micro-LED mask, known as the face-conforming surface lighting micro-LED (FSLED) mask. This innovative design ensures consistent photostimulation of the dermis. The technology’s core advantage is its ability to deliver light evenly to the deeper skin layers while maintaining a close contact with the surface of the skin. This is accomplished through a unique 3D origami structure that houses 3,770 micro-LEDs and features a flexible layer for light diffusion, which minimizes the spaces between the light source and the skin.
In trials with 33 participants, the FSLED mask showed a remarkable 340% enhancement in deep skin elasticity compared to regular LED masks, demonstrating its effectiveness in reducing wrinkles, sagging, and signs of aging.
Professor Keon Jae Lee remarked, “The FSLED mask offers cosmetic improvements to the entire facial dermis without the risks associated with low-temperature burns, enabling a home-care anti-aging treatment that can significantly boost quality of life. The product is currently being produced by Fronics, a startup from KAIST, and will be globally available through Amorepacific’s distribution channels, with sales set to begin in November.”
