Nonablative laser works by creating rapid sequential heat pulses, which are compounded and transferred deeper into the mucosa. The fast heat pulsing results in tightening of the mucosa and stimulation of new collagen formation, without injuring the tissue surface. It restores tissue quality, but it works in a nonablative manner, leaving the surface intact. In this way, the risk of unwanted side effects, especially after multiple repeated treatments, is greatly reduced. For the aforementioned reasons, this is treatment of choice for vaginal laxity patients.
