Outcomes of 1064-nm picosecond laser alone and in combination with fractional 1064-nm picosecond laser in tattoo removal.

J Cosmet Dermatol 2022 Apr 29. Epub 2022 Apr 29.

Division of Dermatology, Chulabhorn International College of Medicine, Thammasat University, Pathum Thani, Thailand.

Background: Removal of the unwanted tattoo was initially focused treatment of picosecond laser in the setting of the unfractionated beam, whereas the fractionated 1064-nm picosecond lasers (Fr-Pico) has been successfully utilized in various skin conditions, including scar and benign pigmented lesions. However, no studies compare the combination of Fr-Pico and unfractional 1064-nm picosecond laser (UFr-Pico) and UFr-Pico alone in tattoo removal.

Objective: This study aims to compare the efficacy and safety of the combination of Fr-Pico and UFr-Pico and the UFr-Pico and in tattoo removal. Read More

Department of Chemical Science and Technologies, University of Rome Tor Vergata, Via della Ricerca Scientifica, 1, 00133, Rome, Italy.

The tattoos removal has become an issue upon spread of the tattooing practice worldwide and hindsight regrets. Lasers are typically used for the purpose, though some colours such as green are considered "recalcitrant" to the treatment. In the current investigation, we aim at determining the efficacy of removal of a green ink water dispersion, using 5 laser treatments: Nd:YAG nano- and picosecond lasers in normal and array mode and Ruby nanosecond laser, keeping the total irradiated energy constant.

Laser-induced sound pinging for the rapid determination of total sugar or sweetener content in commercial beverages.

Talanta 2022 Apr 5;240:123034. Epub 2021 Nov 5.

Department of Chemistry, University of Missouri, Columbia, MO, 65211, United States. Electronic address:

We recently reported on fixed-path length laser-induced sound pinging (FPL-LISP) as a rapid photoacoustic technique employing an inexpensive benchtop tattoo-removal laser for reliably determining the speed of sound in low-volume fluids. In this contribution, we demonstrate the capacity of FPL-LISP to analyze representative commercial beverages for their natural or artificial sweetener contents. As a benchmark, the speed of sound was determined for solutions of sugars (glucose, fructose, sucrose), mock high fructose corn syrup (HFCS-55), and 12 household sweeteners (culinary sugars, syrups, honey, molasses) across the concentration range of 1-20% w/v in water, simulating the typical sweetener range found in commercial soft drinks.

Efficacy of a laser with a pulse duration of 300 ps in skin rejuvenation and treatment of pigmentation disorders in Asians: a series of four cases.

J Cosmet Laser Ther 2021 Aug 29;23(5-6):159-162. Epub 2021 Dec 29.

Sungkyunkwan University, Suwon, Korea.

The photothermal effect of lasers is minimized and the photoacoustic effect is maximized as the pulse duration is shortened. Therefore, picosecond lasers with a short pulse and high peak power can be used to effectively treat various pigment disorders by reducing tissue damage. The first picosecond lasers were used for tattoo removal; they are also widely used for pigment treatment because of their reduced side effects compared with nanosecond lasers. Read More

High power Q-switched 1064 nm / 532 nm Nd:YAG Laser in tattoo removal: A systematic review.

J Cosmet Laser Ther 2021 May 20;23(3-4):41-48. Epub 2021 Oct 20.

Coordinator of the Specialized Ambulatory Service in Cosmiatry, University of Campinas (Unicamp), Campinas, Brazil.

Q-switched 1064 nm/532 nm Nd: YAG Lasers present important characteristics which can contribute toward the removal of tattoos, for having the ability to reach only specific targets with minimal damage to the tissue. Despite reports of their clinical benefits, only a few scientific studies demonstrate the efficacy and safety of these types of lasers in the short and long term. To substantiate the effects, benefits, and safety of the application of Q-switched 1064 nm/532 nm Nd: YAG lasers, a systematic review was carried out from September to December of 2019, about the studies which report their use in the removal of tattoos, published in the last 20 years.
