How does laser therapy promote wound healing?

Laser therapy promotes wound healing primarily by enhancing collagen production and increasing blood circulation. Collagen is a crucial protein that plays a fundamental role in the structural framework of tissues and organs. When laser therapy is applied, it stimulates fibroblasts, the cells responsible for producing collagen, which in turn aids in the repair and regeneration of damaged tissue.

Additionally, the increase in blood circulation that results from laser therapy is important for delivering necessary nutrients and oxygen to the wound site. Enhanced circulation also helps to remove metabolic waste products, further promoting a healthier environment for healing. The combination of improved collagen synthesis and better blood flow accelerates the overall healing process, making it an effective method for treating various wounds.

In contrast, the other options do not accurately reflect the primary mechanisms through which laser therapy facilitates wound healing. Reducing hair growth may be a characteristic of certain laser therapies but is not relevant to wound healing. Closing wounds faster is a consequence of the healing process but does not specify the underlying biological mechanisms involved. Promoting skin discoloration is not a therapeutic advantage and is generally considered a side effect rather than a benefit of laser therapy.
