Abstract
|
|
|
|
Fractional lasers, by virtue of rapid healing, provide a means to reduce the complications and downtime associated with ablation lasers, while maintaining a laser thermal effect superior to that of non-ablative rejuvenation (NAR) lasers. Therapeutic effects of non-ablative fractional lasers (NAFL) are achieved by irradiation of multiple micro-treatment zones on the skin. Compared to NAFL, the micro-columnar ablation effect of ablative fractional lasers (AFL) provides superior skin elasticity improvements and skin contraction. Fractional lasers are effective for both aging facial skin rejuvenation and scar improvement. Early treatment of acute stage scars is recommended for better results. With a thorough understanding of the characteristics of NAFL and AFL, clinicians can properly apply each type of laser for satisfactory rejuvenation and scar treatment.
