The non-ablative laser uses a wavelength that does not cause the water in the tissue to evaporate (ablate) but rather the laser energy heats the tissue in a controlled manner. The rise in temperature stimulates neocollagenesis, a process in which new collagen is produced by the body. Collagen is a fibrous protein that is responsible for giving the skin its elasticity and suppleness. By producing new collagen the skin regains is youthful appearance.
Since the treatment does not involve tissue evaporation or ablation, treatment downtime is significantly reduced, which is also why it is preferred over ablative treatments by many patients.
