The laser generated by the beauty instrument is a novel light source, which is essentially an electromagnetic wave. It has the advantages of strong directivity, monochromaticity, good coherence, energy concentration, etc. When laser irradiates organism, it can produce thermal effect, photochemical effect, biological stimulation effect, pressure effect, electromagnetic field effect, etc. At present, medical treatment mainly depends on the first three. The thermal effect produced by the weak laser can make the local temperature reach 38~44 degrees Celsius. It does not destroy the tissue, but has a biological stimulation effect, which can improve blood circulation, promote healing, and enhance immunity.
High power laser can rapidly increase the local temperature by 100 degrees Celsius, or even hundreds of degrees Celsius, and make tissue proteins denature, coagulate, carbonize or vaporize in a short time. This destructive effect is the basis of laser surgery, which is used to destroy and remove pathological tissues to achieve therapeutic purposes. With different lasers, superficial or deep lesions can be treated. The photochemical reaction of laser is commonly used in clinic, which is also called photosensitive therapy or photodynamic therapy. It can eliminate the damage of pathological changes by local laser irradiation after injecting photosensitizer into the body to reach the pathological position.
With the increasing improvement of material and cultural level, people are paying more and more attention to the beauty of appearance, pursuing the perfection of appearance, clothing and costumes, especially appearance, hoping to remove or even change the congenital deficiencies or defects. The rise and development of modern cosmetic surgery provides the possibility for beauty lovers. As a laser technology with unique advantages, it has become a very active member in this field.
Beauty instrument is a new kind of beauty instrument, which replaces the traditional beauty method, and the effect is safe and reliable.
