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

In recent years, there has been a large increase in cosmetic applications using non-ionising radiation (NIR). These applications use various types of NIR such as lasers and ultrasound for numerous cosmetic outcomes such as epilation, skin rejuvenation and tattoo removal. Cosmetic NIR procedures are marketed as a low-cost and low-risk alternative to more invasive procedures. Read More

Objectives: Tattoo removal is in high demand, and many types of lasers can be used for tattoo removal. Macrophages play an important role in the persistence of tattoos. However, comparative studies of the efficacy of tattoo removal with different lasers versus the relationship between the destruction of pigment particles or recruitment of macrophages after laser treatment are lacking.

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.

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.

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

The novel picosecond lasers have emerged as a mainstay device in laser tattoo removal alongside Q-switch lasers, considered the gold standard in the field. Here, we present a 45-year-old female who developed a severe reaction to both her treated and untreated tattoos after two picosecond laser treatments and subsequent widespread eczematous eruption. Skin biopsies revealed findings consistent with hypersensitivity to exogenous red pigment. Read More

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.

Cosmetic tattoos are difficult to remove, and their response to picosecond laser treatment has seldom been investigated. We compared the efficacy and adverse effects of picosecond versus Q-switched lasers for the removal of cosmetic tattoos. White, flesh-colored, and brown inks were irradiated using 532/1064 nm picosecond and Q-switched Nd:YAG lasers, and their absorption spectra before and after laser irradiation were analyzed.

Tattoos with blue/black ink show good lightening of pigment after treatment with 1064 nm Q-switched (QS) neodymium-doped yttrium-aluminium-garnet (Nd:YAG) laser. In this randomized trial, we compared the efficacy of a novel three pass, one session procedure (R15 method) with a conventional method for treating blue/black tattoos in darker skin types. Tattoos were treated with 1064 nm QS Nd:YAG Laser with a spot size of 4 mm, fluence of 5 J/cm and frequency of 5 Hz. Read More

Comparative laser and thermal treatments were carried out on PG36, a green phthalocyanine-based pigment, permitted in European countries where legislation on tattoo composition was issued. Prior to the treatments, PG36 was characterized by SEM imaging, EDX, IR and UV-Vis spectroscopies, revealing an excess of Si and C and O as compared to the pure halogenated Cu-phthalocyanine. Laser treatments were carried out with a Nd:YAG device applied to HO and propan-2-ol dispersions. Read More

Background: Clinical outcomes of tattoo removal vary widely among different patients; it is known that tattoo-related features (such as pigments' type or quality, the use of multicolored inks, tattoo location size, location, layering, and duration) and personal habits (as smoking or skin phototype) could influence the clinical response to treatment, the possible role of nutrition in affecting the laser treatment of tattoos has never been investigated.

Aims: This study aims to compare the clinical response of tattoos removal between omnivore and vegan patients treated with Q-switched laser (QSL).

Patients/methods: Twenty omnivore and twenty vegan patients treated for professional black tattoo removal with Nd:YAG QSL were enrolled in this study. Read More
