Treatment of Atrophic Facial Acne Scars With the 1064-nm Q-Switched Nd:YAG Laser

Laser induced collagen remodeling: A comparative study in vivo on mouse model

“…As demonstrated in our study that the Q-switched 1,064-nm Nd:YAG laser promotes the most synthesis of collagen type III, which is the predominant collagen in youth skin, our results suggest that the Q-switched 1,064-nm Nd:YAG laser treatment modality may be more effective in increasing the elasticity of treated skin. Recent published results [32,33] demonstrated that Q-switched 1,064-nm Nd:YAG laser leads to significant quantitative improvements in skin topography in patients with mild to moderate atrophic acne scars, and showed a greater response compared with the 1,320-nm laser system, which could be explained by our experimental findings.…”

Successful treatment of acneiform scarring with CO2ablative fractional resurfacing

“…Images were obtained from each cheek in the areas of the most pronounced acneiform scarring pre-treatment and at 3 months following the last treatment. Analysis of these areas was done in standard fashion as previously described [10]. These images were used to analyze the changes in the acneiform scars over time.…”

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

“…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.…”
