What effect can laser therapy have on scar tissue?

Laser therapy can be highly effective in improving the appearance of scar tissue. When applied to scars, laser therapy works by stimulating the underlying tissues, increasing collagen production, and promoting proper healing and remodeling. As the laser energy penetrates the skin, it can help to break down old collagen fibers and encourage the formation of new, more elastic tissue. This process can lead to a reduction in the visibility of scars, making them less noticeable over time.

In contrast, the other choices highlight effects that are not aligned with the benefits of laser therapy on scar tissue. For example, promoting hardening of scar tissue would contribute to a more rigid and undesirable outcome. Enhancing blood circulation is a part of the healing process, but it is not the sole effect of laser therapy; the focus is on improving scar appearance specifically. Preventing the remodeling of scar tissue is contrary to the intended purpose of laser therapy, which aims to facilitate remodeling for better aesthetic results.
