LED face masks are a form of light therapy used to penetrate deep into the skin and accelerate cell processes. Different colors produce different wavelengths of energy, and these different wavelengths trigger different processes. LED masks are designed to rejuvenate the complexion and boost the performance of skincare products and sheet masks. The NURI Mask Infuser, for example, uses thermal technology to open the pores to ensure maximum absorption, while the sonic technology helps push the beneficial ingredients for even product absorption. The negative electrons in ionic technology create a circuit to pull the positively charged skincare ingredients deeper into the skin. The Aphrona LED Face Mask Light Therapy does not contain any harmful ultraviolet rays and is safe and comfortable. The Phera LED Face Mask Light Therapy has four modes: red light, blue light, infrared light + red light, and a revolutionary combo of red and blue infrared light. However, the ingredients or materials used in these masks are not mentioned in the search results.
