Many friends will have a problem when using a photon meter. When should I use red light and when should I use blue light, and what is the difference between red light and blue light?To put it simply, the main difference between red light and blue light is the wavelength, frequency and energy of the two, which leads to the difference in function.
1. Wavelength: The wavelength of general medical red light is 630-640 10nm, in this range, the longer the wavelength, the more obvious the thermal effect (the thermal effect can obviously promote blood circulation, but it will also evaporate human water). The commonly used blue light wavelength is shorter, around 460 10nm, with a data surface, and the blue light ** effect in this band is significantly better than that of other bands.
2. Frequency and energy: The frequency of red light is low, and the energy emitted is mainly thermal energy, while the frequency of blue light is relatively high, and the energy emitted is mainly electromagnetic energy.
3. Function: Red light can penetrate to 8-12cm under the skin, mainly promoting wound healing, inflammation and analgesia. At the same time, it can promote the production of cellular proteins, improve allergic reactions, reduce the formation of acne and scars, and can play a role in removing acne scars and repairing acne scars. Blue light can kill a variety of common bacteria, such as Staphylococcus aureus, Escherichia coli and P. acnes, etc., and play a role in sterilization and anti-inflammatory. At the same time, blue light can regulate the pH value of cells, improve the intracellular fluid environment, purify the skin, effectively inhibit the secretion of sebaceous oil, and prevent acne**.
4. Clinical use: Clinically, the two are usually used together, generally using blue light for sterilization and anti-inflammatory, and then irradiating red light to repair cells and promote healing. Alternating exposure to red and blue light will have a better effect on preventing infection. However, for internal inflammation or pain, irradiation therapy is usually performed with red light. This is because the condition is usually aseptic inflammation or pain, and the blue light does not reach the internal tissues.
