tier1 Comparative Study of a 1064 nm Fractional Picosecond Laser Versus Intense Pulsed Light in Facial Rejuvenation: A Prospective Randomized Trial.
Abstract summary (English) BACKGROUND AND OBJECTIVES: Skin aging, characterized by wrinkles, pigment disorders, and enlarged pores, is driven primarily by photoaging. While a 1064 nm fractional picosecond laser shows efficacy in skin rejuvenation, comparative studies with intense pulsed light (IPL) remain limited. This randomized controlled trial (RCT) aimed to compare the efficacy and safety of the 1064 nm fractional picosecond laser with...

View on PubMedtier1 Comparison of the 1064-nm picosecond laser with fractionated microlens array and 1565-nm non-ablative fractional laser for the treatment of enlarged pores: a randomized, split-face, controlled trial.
Abstract summary (English) PURPOSE: This split-face randomized study compared the efficacy and safety between 1064-nm picosecond laser with fractionated microlens array (MLA) and 1565-nm nonablative fractional laser to treat enlarged pores. METHODS: Participants with enlarged facial pores were enrolled and underwent three consecutive sessions at 2-week intervals with either a 1064-nm picosecond laser with MLA or a 1565-nm nonablative...

View on PubMedtier0_review An update on fractional picosecond laser treatment: histology and clinical applications.
Abstract summary (English) Picosecond lasers have a very short pulse duration and a high peak power density. When fractional optical delivery systems are attached to picosecond lasers, they generate an array of concentrated microspots with a high fluence surrounded by areas with a low fluence. This article discusses the histologic characteristics and clinical applications of fractional picosecond laser treatment.

Abstract summary (English) BACKGROUND AND OBJECTIVES: Facial photoaging is a type of facial skin aging induced mainly by exogenous factors (ultraviolet radiation) and often manifests itself in the form of hyperpigmentation, telangiectasia, roughness, increase in fine lines/wrinkles, and enlarged pores. Recently, picosecond lasers have become an emerging option for the treatment of facial photoaging, and long-pulse alexandrite lasers (LPAL)...

Abstract summary (English) OBJECTIVES: Laser therapy has become one of the mainstay treatments for improving signs of aging including wrinkles, large pores, and skin pigmentation. However, in patients with pigmented skin, an increase in complications including post-inflammatory hyperpigmentation (PIH) has been noted. The purpose of this study is to investigate not only the safety profile of 755-nm picosecond laser with diffractive lens array...
