On October 29, it was reported that a research team led by Professor Keon Jae Lee from the Korea Advanced Institute of Science and Technology (KAIST) had developed an LED beauty mask designed to stimulate deep skin layers. Clinical trials have demonstrated that this mask can improve dermal elasticity by 340%.
Challenges with Traditional LED Masks
Traditional LED masks often fail to conform to the contours of the face, leading to significant light reflection. Reports indicate that the light reflection rate is as high as 90% when the distance from the skin is two centimeters. This results in reduced light penetration, limiting effective stimulation of deep skin layers and negatively impacting skin regeneration.
Innovative Design of the Micro LED Mask
To address these challenges, Professor Keon Jae Lee’s team created a face-conforming surface lighting micro LED (FSLED) mask that provides uniform light stimulation to the dermis. The key technology behind this mask is its ability to transmit light evenly to deep skin tissues while tightly adhering to the skin. Utilizing a 3D origami structure, the mask integrates 3,770 Micro LEDs and a flexible surface light diffusion layer, minimizing the gap between the light source and the skin.
Clinical Trial Results
In clinical trials involving 33 participants, the FSLED mask significantly improved dermal elasticity by 340% compared to traditional LED masks. It also demonstrated notable effects in reducing wrinkles, skin sagging, and signs of aging.
Implications for Home Skin Care
Professor Keon Jae Lee stated that the FSLED mask offers cosmetic benefits for the entire dermal layer of the face without causing side effects such as low-temperature burns. This innovation paves the way for at-home anti-aging treatments. The product will be manufactured by Fronics, a startup company from KAIST, and is expected to go on sale in November.
This research has been published in the academic journal Advanced Materials, under the title “Clinical Validation of Face-fit Surface-lighting Micro Light-emitting Diode Mask for Skin Anti-aging Treatment.”
