A Preliminary Study of Utilization of the 1320-nm Nd:YAG Laser for the Treatment of Acne Scarring

Abstract

The 1320-nm Nd:YAG laser with cryogen cooling significantly improves the appearance of acne scarring.

Second-Generation 1,550-nm Fractional Photothermolysis for the Treatment of Acne Scars

“…Results appear to surpass those reported using nonablative technology such as the 585-nm pulsed dye laser, the 1,064-nm Q-switched Nd:YAG, the 1,320-nm Nd:YAG, and 1,450-nm diode laser. [16][17][18][19][20][21][22][23][24] In summary, second-generation 1,550-nm fractional photothermolysis is a safe and effective modality for the treatment of all types of acne scarring. We found the laser to be safe in patients with FST I to V. We …”

New insights into the management of acne: An update from the Global Alliance to Improve Outcomes in Acne Group

“…Mild overall improvement has been reported with these lasers. [213][214][215][216] A comparison of the efficacy of the 1450-nm diode laser versus the 1320-nm neodymium:yttrium-aluminum-garnet laser for atrophic facial scars in 20 patients with mild to moderate scars suggested better clinical results with the 1450-nm laser. 213 Side effects are generally mild.…”

Comparison of a 585-nm pulsed dye laser and a 1064-nm Nd:YAG laser for the treatment of acne scars: A randomized split-face clinical study

“…[15][16][17][18][19][20][21][22][23][24][25][26][27] However, comparative studies of the various devices are lacking, and to date little histologic or biologic evidence has been presented concerning scar remodeling after nonablative resurfacing. The objective of this study was to compare the efficacies and safeties of a 585-nm PDL and a 1064-nm long-pulsed Nd:YAG laser for the treatment of atrophic facial acne scarring.…”

“…7 Although ablative lasers, such as the carbon dioxide (CO 2 ) and erbium:yttrium-aluminum-garnet (Er:YAG) laser, have been considered as ''gold'' standards for skin resurfacing, adverse effects, such as prolonged postoperative erythema, swelling, and even dyspigmentation, impede their widespread utilization, especially in patients with darker skin. [7][8][9][10][11][12][13][14] In contrast, nonablative remodeling lasers, such as the 1320-nm or 1064-nm neodymium:yttrium-aluminum-garnet lasers (Nd:YAG) [15][16][17][18][19][20][21][22][23] and diode (1450 nm) [24][25][26] lasers, and the 585-nm pulsed dye laser (PDL), 27 can also reduce acne scarring without significant downtime, but at lower efficacies. Moreover, although the recently developed technique of fractional laser skin resurfacing has been reported to allow the recontouring of scars, 28,29 the risk of hyperpigmentation in patients with darker skin types often precludes sufficient treatment 30 ; thus nonablative scar resurfacing is still becoming more popular for acne scar reduction, especially in patients with darker skin.…”
