What beauty device is used to improve skin texture?

LED light therapy home beauty devices emit light from the visible spectrum or outside the visible spectrum, with the depth of penetration increasing as the wavelength of light increases. Common ones include blue light, yellow light (amber light), red light, green light and infrared light. Each of these lights has a different wavelength and is absorbed by receptors at different depths of the skin in a gentle and non-invasive manner, causing the skin to react in different ways to soothe, calm and improve inflammation.

What are the different effects of the different coloured lights on the skin? "Blue light mainly works on Propionibacterium acnes, so it has an anti-acne function. Red light itself has some anti-inflammatory effect and also stimulates collagen renewal, which means skin rejuvenation. The most used lamps in Diwali are blue light and red light," says Li Kai. In addition to red and blue light, many instruments also use yellow light, green light and invisible infrared light. Green light mainly evens out skin tone, improves pigmentation or lightens spots, yellow light is used to relieve redness and inflammation, and infrared light works to the deepest degree and can perform different functions depending on the specific needs of the user. It is also common to use different LED lights in combination or with other optoelectronic technologies such as radio frequency.

It's amazing that the LED masks and "Diwali lights" that are so popular on Western social media don't seem to be as popular in China as they are in Europe and the US. Li Kai believes there are a few reasons for this: Firstly, it is difficult to brush up on a drama or do anything else while wearing a mask or using a Diwali light, so you have to close your eyes and put on the mask. Secondly, beauty devices with enough light masks and large LED lights tend to be expensive, ranging from several thousand to tens of thousands of dollars. Thirdly, it has to do with the consumer mentality, as LED-based devices require the user to be patient enough, as only long-term use can provide good results.
