Fractional Photothermolysis in Skin Rejuvenation

This book chapter focuses on lasers using fractional photothermolysis (FP) technology to rejuvenate and enhance the youthfulness of our skin. FP creates microscopic treatment zones (MTZs) while sparing the surrounding skin, facilitating faster re-epithelization of the treated area. This chapter discusses about the historical background and advancements in ablative fractional laser (AFL), nonablative fractional laser (NAFL), and hybrid lasers. Additionally, it discusses strategies for optimizing outcomes for patients undergoing skin rejuvenation treatments.
