“…In this technique, a negative pressure apparatus producing À300 to À500 mmHg of pressure is applied to the normally pigmented donor site to promote the formation of multiple epidermal blisters. 36 The recipient site is prepared by removing the epidermis through induction of suction blisters, application of liquid nitrogen, PUVA, carbon dioxide laser, yttrium aluminum garnet laser, or dermabrasion 34,38,40,41 (Figure 8). The authors recommend applying a 20-mL syringe with the barrel removed to the skin with lubricant to create a seal.…”
