Laser toning qswitched or picosecond evidence for Tattoo amateur

Abstract summary (English) 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,...

Journal Article, Systematic Review

Abstract summary (English) BACKGROUND: Q-switched lasers are conventionally used for the treatment of black tattoo. However, they require multiple sittings, and the response may be slow due to competing epidermal pigment in dark skin. OBJECTIVE: To compare the efficacy of Q-switched Nd:YAG laser alone with its combination with ultrapulse CO₂ for the removal of black tattoo.

Comparative Study, Journal Article, Randomized Controlled Trial

Abstract summary (English) BACKGROUND AND OBJECTIVES: Perfluorodecalin (PFD) has previously been shown to rapidly dissipate the opaque, white micro-bubble layer formed after exposure of tattoos to Q-switched lasers [1]. The current pilot study was conducted to qualitatively determine if the use of a transparent PFD-infused silicone patch would result in more rapid clearance of tattoos than conventional through-air techniques. MATERIALS AND...

Journal Article, Randomized Controlled Trial

Abstract summary (English) BACKGROUND: Laser beam diameter affects the depth of laser penetration. Q-switched lasers tend to have smaller maximum spot sizes than other dermatologic lasers, making beam diameter a potentially more significant factor in treatment outcomes. OBJECTIVE: To compare the clinical effect of using the maximum-size treatment beam available for each delivered fluence during laser tattoo removal to a standard 4-mm-diameter...

Abstract summary (English) BACKGROUND: With rapid advancement in cutaneous laser therapy, Q-switched lasers have become the standard treatment for tattoo removal. The longer wavelength Q-switched Nd:YAG laser is used when removing tattoos in darker skin patients to avoid scarring and permanent pigment changes. Nevertheless, the local experience revealed that nearly 25% of the Chinese patients developed scarring.

Journal Article, Randomized Controlled Trial

Abstract summary (English) BACKGROUND AND DESIGN: The Q-switched ruby laser was recently shown to remove tattoos without scarring. The Q-switched neodymium: yttrium aluminum garnet (Nd:YAG) laser, which targets black ink with a longer wavelength that has less absorption by melanin, should effectively treat tattoos with fewer pigmentary alterations. A prospective, blinded, controlled study was conducted to assess the ability of the Q-switched...

Abstract summary (English) BACKGROUND: The combination of lasers and acoustic shock waves has shown promising results in accelerating tattoo removal. OBJECTIVE: To assess the effectiveness of treatments combining lasers and shock waves regarding the number of sessions required for successful tattoo removal. METHODS: A prospective, observational, real-world, single-center study including adults (>18 years) with ≥one professional tattoo of any...

Journal Article, Observational Study

Abstract summary (English) BACKGROUND: Various methods for tattoo removal have been employed over the last century, including different methods of laser treatment. Aim To compare three different methods of Q-switched laser treatment. METHODS: A prospective, comparative cohort study was carried out on 17 subjects with tattoos.

Clinical Trial, Comparative Study, Journal Article

Abstract summary (English) BACKGROUND AND OBJECTIVES: The ability to provide improved tattoo fading using multiple laser passes in a single office laser tattoo removal session is limited. In part, this is due to the loss of laser effectiveness caused by epidermal and dermal vacuole "whitening" generated during the initial laser pass at the tattoo site. The Rapid Acoustic Pulse (RAP) device generates acoustic shock wave pulses that clear...

Abstract summary (English) BACKGROUND AND OBJECTIVES: Laser procedures in skin of color (SOC) patients are challenging due to the increased risk of dyspigmentation and scarring. A novel 755 nm alexandrite picosecond laser has demonstrated effectiveness for tattoo removal and treatment of acne scars. No studies to date have evaluated its applications in pigmentary disorders.
