  Fig. 1 Schematic diagrams showing (A) a shallow classic ablation, which may leave a remnant lesion, with lesions having a relatively high rate of recurrence; (B) a deep classic ablation, which is associated with an increased risk of scarring; (C) the pinhole method, in which the laser makes randomly or regularly distributed dot-shaped holes on the lesion; and (D) donut ablation, in which the laser makes line- or donut-shaped holes, or holes of various shapes along the rim of the lesion. (E~G) Photographs of a nevus sebaceus in a 31-year-old female (E) before treatment, (F) one month after three treatment sessions, and (G) one year after the final treatment (six sessions). (H~K) Photographs of a 53-year-old female with xanthelasma on both medial sides of the upper eyelids. (H) Right and (I) left sides before pretreatment. (J) Right and (K) left sides three months after the last of three treatment sessions. (L~O) Photographs of a 40-year-old female with dermal melanosis. (L) Before treatment; (M) generation of a deep donut-shaped hole to remove deep-seated cells; (N) generation of another donut-shaped hole one month after the first session, while avoiding previously treated erythematous areas; and (O) three months after the final treatment (five sessions).
