Subcision and 1320-nm Nd:YAG Nonablative Laser Resurfacing for the Treatment of Acne Scars: A Simultaneous Split-Face Single Patient Trial

Abstract

This case illustrates that dual treatment with subcision and 1320-nm Nd:YAG nonablative laser resurfacing is a well-tolerated and highly effective regimen for the improvement of facial acne scars, compared to subcision alone.

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.…”

Comparing the role of subcision suction method with and without the injection of platelet-rich plasma in the treatment of depressed scars

“…Goodman reported two cases with facial scars improved by subcision using a 19-gauge needle [19] . Fulchiero et al reported a case with acne scars improved by subcision, followed by further improvement after nonablative resurfacing with 1320 nm Nd:YAG laser [20] . These studies lacked patient quantity compared to our study.…”

Fraktionierte nicht ablative Laser

“…Für moderater ausgeprägte Veränderungen sind Filler und Neurotoxine in Kombination hilfreich. Insgesamt ist die Wirksamkeit der nicht ablativ fraktionierten Systeme bei der erapie von Falten als mäßig zu bewerten [19,31,32,33,34,35].…”
