The red LED as Reuters wide range of uses, from the sensor may be used with treatment, but as technology advances, the medical instrument has been increasingly red LED light and compact. In 2012, LED masks have been introduced, which use red LEDs with wavelengths from 633 nm to 660 nm to eliminate wrinkles and shrink pores in a non-invasive manner.
Recently, the Taiwan Institute of Technology has upgraded the LED mask to develop the world's first light film. Using patented technologies such as ultra-thin light-guide film and micro-nano transfer, 48 red 630nm red LEDs can be evenly distributed. Irradiation on the face, and the LED configuration of the light film also avoids the eye, reducing the risk of eye irritation.
Fibroblasts, which are cells that synthesize extracellular matrix and collagen, play a key role in the healing of biological wounds. According to the Institute of Microwave Research, fibroblasts are irradiated for 20 minutes, 24 hours later, fibroblasts. The number can be increased to up to 43.7%, which can slow the loss of collagen.
Compared with large-scale machines, miniaturized LED phototherapy devices are faced with maintaining energy stability and safety. Zhao Zhiqiang, a researcher at the Institute of Measurement and Measurement of the Taiwan Institute of Technology, said that the general beauty salon has a large machine and relatively high energy. The daily dose of red light, the cell proliferation is similar to the results of the clinic once, and the cell tolerance is not a single overdose.
In the future, the Taiwan Institute of Technology will also plan to expand the application of red LEDs, hoping to expand into pregnancy care, skin repair and intimate care.
Red LED lighting was not originally designed for beauty. It started with NASA and the Wisconsin Space Automation and Robotics Center (WCSAR). In order to allow astronauts to plant plants at the airport, they began to study red. Light LEDs, in turn, have been found to have wavelengths that promote plant growth and promote cell metabolism, alleviating astronauts' muscle atrophy and accelerating wound healing.
Studies have shown that red LED spectrum at 680 nm and 730 nm and near-infrared LED lamps at 880 nm have good effects on the skin. The research volume of LEDs has increased with the price drop. Recent studies have also found that blue LEDs and yellow LEDs can delay the growth of acne and soothe sensitive skin.
Decreasing phototherapy
At the Consumer Electronics Show (CES) in the United States, there are also related LED phototherapy devices. The Swedish beauty brand FOREO will combine the UFO and APP, which are cosmetic mirror-sized beauty instruments. The machine is divided into three wavelengths. The blue LED can promote circulation and green. The light LED is to brighten the skin color, and the red LED is to delay the aging. The user can place the corresponding mask on different UFOs and slide on the face for 90 seconds to complete the maintenance.
UFO has LED phototherapy, hyperthermia, cold therapy and special shock wave technology, which can help the skin absorb the essence of the mask and greatly reduce the time of applying the mask. It can also adjust the wavelength intensity and the frequency of the machine vibration by using APP. Skin quality is adjusted.
However, phototherapy machines are not a beauty panacea. Not everyone can use phototherapy equipment. For those suffering from cataracts, glaucoma and other eye diseases, they also need to wear protective goggles to avoid eye damage and redness, itching and other allergies to light. The phenomenon of light-sensitive body is also not suitable for the use of phototherapy equipment.
