Users can calm their emotions and focus by illuminating the skin with blue light; red light can be used for the proliferation of collagen, improving small lines, pores, and swelling after surgery.
In this regard, many people who love beauty not only go to the beauty salon to spend money, but even buy LED beauty instrument to improve the skin, but some people say that the LED light meter is not very effective, what is the truth? CCTV reporter launched an investigation.

The author interview found that many citizens want to try to improve the skin with LED beauty instrument.
After the birth of the baby at the end of last year, Ms. Zhang of Lanzhou felt that her skin was not as good as before. For this reason, she bought so-called high-tech beauty products such as beauty instruments and beauty bars. Recently I heard that the LED light meter can improve the skin, and she is busy studying it. "In fact, I don't really believe that this can improve the skin, but now the skin is not over, so I have to work hard to improve." Ms. Zhang said.
Unlike Ms. Zhang, Ms. Yu was originally dry skin. Recently, the weather in Lanzhou has become cold. The cold wind on the road is very strong, and the skin is more dry, especially the small lines appearing in the corners of the eyes, which makes her a little anxious. "It should be able to improve the skin." Ms. Yu said. She is going to go to the beauty salon to experience it first. If it is effective, she will prepare for the blood, and buy an LED light meter online.
Author survey: need to use multiple times to be effective
The author visited several beauty salons in Lanzhou, and their staff claimed that the equipment they used was professional equipment approved by the state and had no side effects to improve the skin.
In the experience event launched by a beauty salon in Lanzhou, there is a blue light project. The author called the customer in the name of the customer, the staff said: "Beauty through the LED light meter, no side effects, can improve the skin."
Then the author came to the beauty salon and found that many customers were lying on the bed with a mask on their faces and a blindfold on the face. The staff on the side turned on the light meter and it ended in about ten minutes. The staff of the beauty salon said: "We use imported equipment. Many customers have set up a package. Every week, we use LED light meter to improve the skin fine lines."
In a local beauty shop, the staff told the author that the LED illuminator they used was a company-specific device, and the acne effect was very good, even if it promised invalidity, it could be refunded. According to the staff, the device has no side effects and is a state-approved device, but first a skin test is performed to determine the treatment package based on skin problems and conditions.
In another beauty salon, the staff claimed that there was no difference between the equipment they used and the hospital. In terms of cost, the general course of treatment is 12 times and it costs 6800 yuan. When the reporter asked whether he could buy equipment at home, the staff said: "Our equipment has no side effects, but it needs to do professional skin tests before use. Ordinary people may not be able to choose the method that suits them."
Doctor: LED illuminator can really improve the skin
Wei Yuping, chief physician, medical doctor and associate professor of the Department of Dermatology, Second Affiliated Hospital of Lanzhou University, said that the LED illuminator is clinically a range of photodynamic therapy and can indeed improve the skin, but it must be used properly.
Wei Yuping, chief physician, medical doctor and associate professor of the Department of Dermatology, Second Affiliated Hospital of Lanzhou University, said in an interview with CCTV. The LED illuminator is clinically a range of photodynamic therapy, which can actually improve the skin, but it must be used properly.
Wei Yuping explained that LED illuminators use light to treat, not heat. The skin is generally composed of epidermis, dermis and subcutaneous tissue. Red and blue light can stimulate the metabolism of each cell mitochondria, which has a certain effect. Such as red light, wavelength 635 nm, in medical clinical, red light can promote wound healing and increase the phagocytic ability of white blood cells; in beauty, it can stimulate and promote cell metabolism, collagen proliferation, can be applied to the skin. Tightening the pores, while the skin has inflammation or red light. Blue light has a wavelength of 415 nanometers. In medical clinical practice, blue light has a bactericidal effect, so it is generally used to treat hemorrhoids; in beauty, it has a proper sedative effect on the skin, which can calm emotions and concentrate. However, Wei Yuping believes that the effect claimed by the merchants is still exaggerated.
In fact, in general, large hospitals will have red and blue devices. Wei Yuping said: "Ordinary people can also choose to purchase equipment to improve their skin, but we must pay attention to the fact that the products selected must be certified by the state. Because some products are especially small. The equipment produced by the manufacturer, the wavelength of red and blue light does not meet the relevant regulations, the effect is not great. In addition, the frequency of use of red and blue light equipment should not be too high, not more than twice a week."
It can be seen that the LED light meter can improve the skin and is true. Although cold light source is a natural treatment for skin regeneration, experts also remind the public that the frequency of using LED light meters should not be too high, up to two times a week. At the same time, the improvement of the skin is also related to many factors such as sleep, mood, physical condition, etc., and cannot rely on this method alone.
