Is the LED red and blue light beauty instrument that can whiten and rejuvenate the skin and eliminate acne in the beauty salon reliable? Many young girls have doubts about this issue. What is the LED red and blue beauty instrument? Why does my skin get better after using this instrument? Will red and blue light radiation harm my skin? Below we will introduce in details the working principle of the LED red and blue skin beautifying device and the scientific judgment of whether the beautifying device is working with the UV radiometer.

1. LED red and blue beauty instrument working principle

The LED red and blue beauty instrument mainly uses red light around 630nm and blue light with a wavelength of 415nm. The red light of 630nm can penetrate the surface of the skin to promote the growth of collagen, make the skin plumper and play the role of whitening, tenderizing and anti-aging. High-purity 415nm blue light acts on the surface of the skin, which can activate P. acnes endogenous porphyrins into high-energy unstable porphyrins and then combine with three-state oxygen to form unstable toxic singlet oxygen. After binding with the compound on the cell membrane, it searches for the cell membrane, which leads to the death of Propionibacterium and plays a bactericidal effect. It can also inhibit the secretion of sebaceous gland oil. Many people worry that their skin will get hurt when used. The LED red and blue beauty instrument uses a narrow-spectrum LED cold light source, which emits cold light and does not generate high heat, so it will not burn the skin.

Does the home red and blue beauty instrument have any effect? This is a problem that many people care about. Compared to regular visits to the hospital for beauty treatments, some people feel that it is not very convenient to buy a household LED red and blue beauty instrument, which can be used anytime and anywhere. However, the comparison between the household LED beauty instrument and the medical device is indeed much weaker.

Why do you say that? The hospital's LED red and blue beauty instrument uses thousands of LED lamp beads, which emit high-purity red and blue light. The home beauty instrument generally only has dozens to hundreds of lamp beads, the wavelength is not accurate and the energy is relatively weak. According to the editor, there is an imported medical LED red and blue beauty instrument, the output intensity of red light is 106 mW/ cm² and the energy is 128 J/ cm²; the output intensity of blue light is 42 mW/ cm² and the energy is 50 J/ cm² . It only takes 20 minutes to complete a simple beauty. In the same time, the output power and energy of the domestic LED red and blue beauty instrument is much smaller than that of the medical one, so the beauty time will be longer. Manufacturers of LED red and blue beauty devices often need to confirm the consistency of the products leaving the factory and confirm that each beauty device that leaves the factory can output the same radiation intensity and energy within a certain period of time. Beauty salons also need to make sure that the irradiation intensity and energy of the beauty instrument have not declined after long-term use. UV radiometer can be used to detect the intensity and energy of blue light radiation.

One of our customers bought the LS125+UVALED-X0 UV light meter to measure the intensity and energy of the LED red and blue beauty instrument. Linshang UV radiometer has a spectral range of 340nm-420nm and is calibrated to a 395nm LED light source. The blue light used by the LED red and blue beauty instrument is exactly 415nm, which can be measured with this ultraviolet irradiator and the measured data can be used as a reference. The power measurement range is 0-20000mW/cm², and the energy measurement range is 0-9999999mJ/cm². Turn on the LED red and blue beauty instrument, place the probe under the light source, and the intensity value and energy value of the light source are immediately displayed on the display of the host.

With the help of the LS125+UVALED-X0 UV radiometer, we can simply measure the effect of the LED red and blue beauty instrument. The main unit of LS125 uv meter can be equipped with 9 types of probes, which can measure UV-A, UV-B, UV-C and other wavelengths. For more information on UV measurement, welcome to consult the professional UV irradiometer manufacturer-Linshang Technology.
