What is the application of 650nm laser in skin?

The 650 nm laser belongs to a low-energy laser, and its power density is much smaller than the damage threshold of the body and blood. When performing extravascular laser irradiation, the laser penetrates the human body without causing any damage to the body. There are a large number of clinical applications at home and abroad. Low-energy laser treatment of "three high symptoms" and cardiovascular and cerebrovascular diseases has a history of nearly 30 years. No reports of toxic and side effects have been reported. It is a recognized physical therapy with no toxicity and no side effects.

The laser irradiation power density is much smaller than the damage threshold of the body and blood, so it does not damage the muscle and blood components. When the platelets gather, the platelet aggregation is reduced by laser irradiation, but the number of platelets is not reduced. Laser medical research can be concluded that laser irradiation of blood can increase the function of white blood cells and phagocytic cells, thereby improving the body's immunity. So it is good for the body.
