“…However, these procedures have limited efficacy and can lead to scar formation and long recovery times. 6 Laser tattoo removal was first reported by Goldman et al 7 and its mechanism can be explained using selective photothermolysis and photoacoustic principles. According to traditional photothermal theory, light energy is selectively absorbed by the target pigment.…”

“…ICT refers to the time required by the pressure waves to traverse a target object. 6 Mechanical stresses (photoacoustic effects) can destroy particles when the laser duration is shorter than the ICT of the chromophore. 1 Thus, a principle of photoacoustics is that the laser beam produces a strong sound wave inside the pigment particle, leading to its rupture.…”

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. Materials and Methods: Tattoo models were established on the rat dorsal surface and randomly treated with 1064 nm nanosecond, 1064 nm picosecond, 755 nm, and 595 nm lasers for one session. Clinical photographic evaluation, melanin index, hematoxylin and eosin staining, identification of macrophages by CD68 staining, and transmission electron microscopy were conducted at different time points. Results: Regardless of the pulse duration, all lasers included were effective for the removal of black tattoos, with 1064 nm lasers having the best efficacy, followed by 755 and 595 nm lasers. The diameter of the pigment particles and recruitment of dermal macrophages correlated with the efficacy of tattoo removal. Conclusions: In this study, the 1064 nm lasers were found to be the most effective for black tattoo removal. However, there was no significant difference between the 1064 nm picosecond and the nanosecond lasers. Macrophage recruitment plays an essential role in pigment metabolism during laser-tattoo removal.

Tattoo removal is a well-established procedure in dermatology. Lasers represent the gold standard in the management of this condition nowadays. In this study, we report our experience on the use of a Q-switched nanosecond source. A total of 52 patients were consecutively enrolled in performing tattoo removal at Magna Graecia University of Catanzaro and Tor Vergata University of Rome. Black and blue tattoos were treated with a 1064 nm laser, with a pulse duration of 6 ns and a fluence up to 10 J/cm2, while colored tattoos were treated with sessions of 532 nm laser, with a pulse duration of 6 ns and a fluence up to 5 J/cm2. Up to nine treatments with a minimum interval of 8 weeks between each session were performed. A six-month follow-up visit assessed patient satisfaction (Visual Analogue Scale). Overall clinical result was assessed with a clinical evaluation by two blinded dermatologists using a 5-point scale, comparing pictures before treatment and at follow up. A total of 52 patients were included and analyzed: 30 females (57.7%) and 22 males (42.3%). Mean age was 43.7 ± 12.7 years. According to Fitzpatrick’s skin classification, 16 individuals (30.8%) were type II, 15 (28.8%) were type III, and 21 (40.4%) were type IV. Most of the treated tattoos were carried out by professionals. The mean number of sessions required to obtain a result was 4.6 ± 2.5, and the final tattoo removal rate was 60% or higher, with 51.9% of the patients reporting highest satisfaction scores Q-Switched 1064/532 nm laser may be considered today as the gold-standard treatment for tattoo removal. Our results confirm literature findings of the safety and effectiveness of these devices.

Picosecond Q-Switched 1064/532 nm Laser in Tattoo Removal: Our Single Center Experience

Background: Tattoo removal is becoming increasingly popular, and Q-switched lasers represent the gold standard in the treatment of this condition. In this study, we report our experience with a new Q-switched picosecond laser device, evaluating its effectiveness and safety. Methods: A total of 34 patients asking for tattoo removal were consecutively enrolled in this open study. The clinicians decided on operating settings based on the Fitzpatrick phototype, the type of tattoo, and the tattoo location. A maximum of seven sessions, with a minimum interval of eight weeks between each session, were performed. At the six month follow-up visit following the last treatment session, patient satisfaction was assessed using a visual analogue scale and two dermatologists evaluated the aesthetic outcome based on pictures taken before and after treatment. Results: A total of 34 patients were included and analyzed: 17 females (50%) and 17 males (50%). The mean patient age was 43.6 ± 11 years. Participants’ Fitzpatrick skin type ranged from II to IV. The mean number of treatment sessions performed was 3.3 ± 2.0 per patient. Over 40% of patients showed complete removal of the tattoo, with most of the patients indicating satisfaction with the treatment. Conclusions: The Q-switched 1064/532 nm laser may be considered the gold standard treatment for tattoo removal. Picosecond pulses seem to guarantee fewer sessions and excellent results when compared to other laser systems in tattoo removal.
