“…12,20,21 This increase in dermal collagen and elastin content has been associated with clinical skin texture and erythema improvement, increased dermal thickness as well as reduced pore size and wrinkles. 12,22,23 The presented study demonstrated the benefits of quasi long-pulse (microsecond pulse duration) Nd: YAG 1064 nm laser as an alternative treatment option for active acne lesions. The proposed regimen led to significant reductions in acne severity after each treatment session starting from the second treatment, until minimal AGSS scoring was achieved.…”

Background: Acne vulgaris is common dermatologic condition with an estimated prevalence of 80%. Acne has been shown to have a significant impact on patient quality of life and mental health, especially as inflammatory lesions typically occur on cosmetically sensitive areas with the potential for permanent scarring. There have been numerous advances in the treatment of inflammatory acne with light-based and laser devices. This technology permits effective treatment of active acne and scarring, with a short recovery and a decreased side effect profile as compared to medicinal standard-of-care and photodynamic therapies.Objective: The case series study was aimed at evaluating the safety and efficacy of a 1064 nm Nd: YAG Quasi-longed pulse laser treatment for acne vulgaris.Methods: This was a prospective study of 19 subjects with moderate to severe. All subjects received 1064 nm Nd: YAG Quasi-longed pulse laser treatments, at 8 J/cm 2 fluence and accumulated 1000-4000 kJ according to treatment area at two weeks intervals. Primary end point was reaching a minimal AGSS score of between 1 and 2.Acne severity was assessed by two independent dermatologists according to AGSS scale before each treatment session and at the follow-up visit (8 weeks following last treatment). Subjects' self-assessment of Patient Global Impression of Change (PGIC) and overall satisfaction were also recorded. Safety was assessed by recording pain, adverse events, and downtime throughout the trial.Results: Investigator's US FDA AGSS scoring of acne appearance improvement shows an average of 6.6 treatments were required to reach the minimal AGSS score endpoint.Significant reduction in AGSS scores was recorded after 2 treatments (4.21 ± 0.65 vs 3.05 ± 0.83 p = 1.63E −05 ), and maintained a statistically significant reduction rate throughout the trial. Minimal AGSS scores were still detected after 8 weeks following final treatment. Subjects scored high satisfaction rates and PGIC scores (2.9 and 5.3, respectively). Some patients reported transient erythema as only adverse events recorded in the study. Conclusion:The 1064 nm Nd: YAG Quasi-longed pulse laser was found to be safe and highly effective for the treatment of facial acne. The treatments were well tolerated, | 2103 ARTZI eT Al.

“…Calabaro et al reported that the WSRS is a valid instrument with a good intra-and interobserver agreement, but no statistical analysis has been used in this study. Furthermore, the use of a scale or questionnaire to assess patient satisfaction is very important to determine patient aspect and satisfaction degree; patient satisfaction appears as an essential item but these subjective clinical assessments lack the precision of the quantitative methods [12,21,22,26,28,42,44,46,47].…”

“…Quasi‐long pulsed 1064 nm laser treatments have also been used in skin rejuvenation mainly in the treatment of small vessels and facial pore size reduction 4,8‐10 . It is speculated that the relative longer pulse duration (microseconds) causes a photothermal effect which in turn induces dermal coagulation.…”

Background Non‐ablative fractionated lasers for facial rejuvenation are increasingly preferred over ablative lasers due to their minimal downtime and fewer adverse events. The synergistic effect of the Q‐switched fractional (QSF) 1064‐nm neodymium‐doped yttrium aluminum garnet (Nd:YAG) laser, in combination with the non‐fractional microsecond pulsed technology has yet to be fully evaluated. Aim Our objective was to determine the safety and efficacy of this combination treatment for skin rejuvenation. Methods Patients who underwent treatment using the QSF‐Nd:YAG laser, followed by the non‐fractional microsecond pulsed Nd:YAG were evaluated retrospectively using a novel 3D imaging modality for degree of facial erythema, wrinkles surface area, and wrinkle depth. Pain perception, adverse effects, and patient satisfaction were assessed at the 2‐month post‐treatment follow‐up visit, graded on a scale of 1‐ 5 (1 = not satisfied, 5 = very satisfied). Results Ten female patients’ ages 44‐67 (mean 55 years) completed both treatment and follow‐up period, with an overall mild improvement in facial erythema and wrinkle surface area (mean improvement of 18% and 19.5% accordingly), as well as a mild improvement in overall wrinkle depth. Pain and adverse effects were mild and transient. Patients' satisfaction was high. Conclusion The combination of the QSF‐Nd:YAG laser and non‐fractional microsecond pulsed technology, using a single Nd:YAG 1064 nm laser platform, was found safe and effective as a non‐ablative modality for facial rejuvenation, as demonstrated by a novel 3D imaging modality.
