tier1 Comparison of the fractionated Nd: YAG 1064-nm picosecond laser with holographic optics and the fractional CO2 laser in atrophic acne scar treatment: a prospective, randomized, split-face study.
Abstract summary (English) KEY POINT: The 1064-nm picosecond laser with holographic optics demonstrated significant efficacy in treating atrophic acne scars. BACKGROUND: Picosecond lasers with fractionated optics have enabled the development of a breakthrough skin rejuvenation method. The authors compared the fractionated, non-ablative neodymium-doped yttrium aluminum garnet 1064-nm picosecond laser with holographic optics and the fractional...

Abstract summary (English) BACKGROUND: The 1064-nm Nd:YAG picosecond lasers using fractional micro-lens array (P-MLA) was a promising therapy for skin resurfacing. However, no studies have compared P-MLA with ablative fractional 2940-nm Er:YAG lasers (AF-Er) in the treatment of atrophic acne scars. OBJECTIVES: To evaluate the efficacy and safety of P-MLA and AF-Er for the treatment of atrophic acne scars.

Abstract summary (English) A picosecond-domain laser reportedly elicits positive treatment outcomes for acne scar and enlarged pores, but multiple sessions are often required. We sought to evaluate the efficacy of one-session fractional picosecond 1064-nm laser in treating atrophic acne scar and conspicuous pores. Fifty-nine acne scar patients with skin phototypes III and IV were treated with picosecond 1064-nm laser with microlens array...

Abstract summary (English) BACKGROUND AND OBJECTIVE: Fractional 1064-nm picosecond-domain laser has recently been utilized for the treatment of atrophic acne scars and showed promising results. However, data on the safety and efficacy of this procedure in dark-skinned patients are limited. This prospective, self-controlled study was conducted to objectively evaluate the safety and efficacy of a 1064-nm picosecond laser coupled with a...

Abstract summary (English) BACKGROUND: The diffractive lens of the picosecond laser is relatively new, and there are few reports on its efficacy in treating atrophic acne scars, especially in Asian populations. OBJECTIVE: Evaluating the efficacy of diffractive lens 755-nm picosecond laser for atrophic acne scar treatment in Asians. PATIENTS AND METHODS: Forty-two patients who were treated for facial atrophic acne scars at a private...
