Is It Possible to Reshape the Body and Tone It at the Same Time? Schwarzy: The New Technology for Body Sculpting

Background and Objective: In recent years, a strong desire for slimmer and healthier-looking bodies has grown in the population. The aim of this study was to evaluate the effectiveness and safeness of the new technology Flat Magnetic Stimulation for buttock and abdomen remodeling in athletic subjects. Methods: A total of 49 patients (31 females and 18 males) were enrolled. Patients’ digital photos and buttocks/abdomen circumference measurements were taken to assess and monitor the effectiveness of treatment on muscle firming. The level of patient satisfaction was evaluated by a questionnaire based on a seven point Likert scale. Average scores were calculated at a 1-month follow-up (FU). Results: A significant increase in the buttocks’ mean circumference from 85.5 ± 0.7 cm to 88.5 ± 0.7 cm (p p Conclusions: Our data show that FMS treatment could be used as an effective mechanism for muscle toning

Laser emission at 675 nm: In vitro study evidence of a promising role in skin rejuvenation

Introduction: Light-based therapies have been proven to influence and perhaps reverse skin ageing at clinical, molecular and histologic levels. Laser technology decreases photodamage by promoting collagen type I and III synthesis and enhancing the expression of heat shock protein. Aims: This study aims to assess different doses of 675 nm irradiation on human dermal fibroblast cells to evaluate the potential therapeutic effects on the rejuvenation process. Methods: This study employed a laser system that emits 675 nm wavelength: 260, 390, 520 and 650 J/cm2 doses were tested on adult human dermal fibroblast cells. Cellular viability, proliferation, and synthesis of type I and III collagen were studied. Results: No dose tested showed effects on cell viability and proliferation at 24 and 48 h from the irradiation. Doses of 260 and 520 J/cm2 causes a significant decrease in type I collagen fluorescence intensity, while 390 J/cm2 elicits a significant increase in type III collagen expression. Conclusions: Our results showed that 675 nm laser irradiation does not affect cell viability while modulating cell proliferation and collagen synthesis in human adult cultured fibroblasts in vitro. These findings suggest that 675 nm laser irradiation potentially plays a role in skin rejuvenation

Ex Vivo Human Histology Fractional Treatment with a New CO₂ Scanner: A Potential Application on Deep Scarring

Background and Objectives: For many years, fully ablative laser treatments, particularly those performed with a carbon dioxide (CO2) laser, were regarded as the gold standard for resurfacing. This study’s goal is to assess the depth that can be reached by a new CO2 scanner system, through a skin model with greater dermal thickness, to use in the treatment of deep scarring. Materials and Methods: Male human skin tissue was laser-treated using a CO2 fractional laser and a new scanning system, and all samples were fixed in 10% neutral buffered formalin, dehydrated using a series of crescent alcohol, embedded in paraffin, sectioned in series (4–5 µm thick), stained with haematoxylin and eosin (H&E), and then analysed under an optical microscope. Results: From the epidermis through the underlying papillary and reticular dermis to various depths of the dermis, microablation columns of damage and coagulated microcolumns of collagen were observed. The reticular dermis was fully penetrated up to 6 mm at higher energy levels (210 mJ/DOT), resulting in deeper tissue injury. Although the laser might penetrate further, the skin stops there, leaving just the fat and muscular tissue. Conclusions: The deep layers of the dermis can be penetrated by the CO2 laser system throughout the entire dermal thickness when using the new scanning system, suggesting that this laser’s potential impact, at the selected settings, covers all skin targets required to perform superficial or deep treatments on any dermatological issue. Finally, patients who have problems, such as morbid scar-deep complications, which affect their quality of life, are more likely to profit from this innovative technique

1064 nm Q-Switched Fractional Laser for Transcutaneous Delivery of a Biostimulator: Efficacy and Safety Outcomes of a Split-Face Study

Background: Laser-assisted drug delivery is a promising strategy that enhances topical treatment by increasing cutaneous permeation and reducing side effects. In cosmetic settings, the efficacy and safety profiles of a treatment must meet the need of a painless procedure with fast recovery. In this context, Q-switched laser appears promising as it can open cutaneous pores without creating a carbonisation barrier. Methods: A split-face study on patients presenting for cosmetic procedures at IDI-IRCCS, Rome (30 September–18 October 2023), was conducted. Pan-facial Q-Switched laser was followed by a topical biostimulator applied on half of the face. Post-procedure local reactions were recorded together with patients’ perceptions. Cutaneous elasticity and hydration were assessed at baseline and three-week follow-up. The Skindex17 questionnaire evaluated the procedure’s impact on patients’ life quality. Also, participants and physicians expressed satisfaction with the treatment. Results: The procedure was well tolerated by patients; local reactions include transitory erythema, superficial bleeding, and oedema, none of which had an impact on daily life. An improvement in skin quality was documented objectively and subjectively by patients and physicians. Conclusion: Q-switched lasers emerge as promising devices for drug delivery, especially for cosmetic reasons. Indeed, the low risk of local reactions together with a remarkable increase in cutaneous permeation make this a suitable strategy for cosmetic procedures
