Background
Body contouring is a significant area of dermatologic and plastic surgery. Surgical procedures, like surgical lipectomy, and less invasive procedures, such as various liposuction ...techniques, are the two main ways to reduce fat.
Aim
Our study showed that 1444 nm Nd:YAG laser‐assisted lipolysis used with appropriate and specific parameters effectively destroys adipose tissue avoiding these risks and determining a safe clinical application.
Method
A subcutaneous, 1444 nm Nd:YAG laser was used on 132 patients (range, 18–73 years; 109 women and 23 men with Fitzpatrick skin phototypes ranging between II and V) requiring body and face contouring. All patients were photographed for documentation. Digital clinical photography was taken under as near identical conditions as possible at baseline (pre‐treatment), and 16 weeks post‐treatment. The 5‐point Global Aesthetic Improvement Scale (GAIS) was recorded immediately after treatment and at their final assessment session (4 months). Adverse events were monitored.
Results
On the basis of the investigator‐evaluated GAIS scale, the total GAIS scores showed satisfactory results. Clinician assessment from the clinical photography showed good efficacy and visible aesthetic results for body and face areas. No serious or unexpected adverse side effects were recorded, and transient pain, oedema, erythema and slight induration resolved within the first week of treatment.
Conclusions
The 1444 nm Nd:YAG laser is a new tool for performing lipolysis, and this study reports its effectiveness and safety.
Background
The body contour market has grown steadily over the last years, due to the persistent demand for non‐invasive treatments for localized fat adiposities, cellulite, and skin laxity.
...Materials and Methods
The purpose of this observational study was to evaluate the efficacy and safety of a new device delivering microwaves (MWs) energy for unwanted fat and cellulite reduction after a full cycle of treatments and 1 year later. A total of 45 patients with localized adiposity and/or cellulite in different body areas (inner thigh, upper arm, abdomen, culotte de cheval, buttocks), received four treatment sessions, 4 weeks apart. Photographic records and global aesthetic improvement scale (GAIS) score were performed.
Results
For the treatment of cellulite the average GAIS score passed from 3.65 ± 0.49 at 1‐month follow‐up (1MFU) to 2.7 ± 0.66 at 1‐year follow‐up (1YFU). For the treatment of localized adiposity, the average GAIS score passed from 3.52 ± 0.51 at 1MFU to 2.82 ± 0.88 at 1YFU. No particular red area was detected either during or after the treatment. There was no mention of assessment of pain or side effects.
Conclusions
The study findings showed that MWs allow for the treatment of cellulite and localized fat adiposity in a safe and effective way, with results lasting over time up to 1 year after the end of the treatment.
Sebaceous adenoma (SA) is a rare solitary tumor that preferentially affects the forehead and scalp. The objective of this case report was to determine the efficacy and safety of a 10,600-nm carbon ...dioxide (CO
2
) laser device in the treatment of large scalp SA, using a new scanning system which allows to speed up the removal of the lesion. A 65-year-old male with SA on the scalp area underwent one session with the CO
2
laser system. For this procedure, a new scanner system with 7-inch or 4-inch focal handpieces were used. A local anesthesia with lidocaine was performed before laser treatment. Some possible side effects such as dyschromia, burning sensation, bleeding and mild to moderate post-treatment erythema, itching, crusting, and edema, were checked. In order to monitor the effectiveness of the treatment, clinical photos that documented the patient lesion were captured before treatment and at 1 month of follow-up. The clinical and aesthetic results observed after laser procedure were excellent, with a complete remission of patient’s scalp SA lesion at 4 weeks’ follow-up. Patient satisfaction was very high, and no side effects were observed. This laser system technology allows for precise, effective, and targeted action on the lesions treated while simultaneously protecting the surrounding areas, ensuring the best possible re-epithelialization.
Background and Objectives: For many years, fully ablative laser treatments, particularly those performed with a carbon dioxide (COsub.2) 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 COsub.2 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 COsub.2 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 COsub.2 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.
The options for treating pseudogynecomastia are limited, and there is a growing demand for noninvasive breast fat reduction. We evaluated the efficacy and safety of a laser-assisted lipolysis (LAL) ...device emitting 1444 nm for the treatment of pseudogynecomastia.
A total of 9 male patients diagnosed with pseudogynecomastia underwent laser procedure with a Nd:YAG laser emitting at 1444 nm. The goal was to generate adequate heat propagation and thermal action in the dermis as homogeneous as possible to induce fat cell lipolysis. The results were clinically evaluated by comparing pictures at baseline and 4 months later.
An independent comparison of baseline and post-treatment pictures by a physician evaluator 4 months after treatment revealed significant improvement in all patients. Three subjects (33%) showed grade 4 improvement; 4 (44%) showed grade 3 improvement, and 2 (22%) showed grade 2 improvement. Breast sizes decreased in all patients 4 months after 1444-nm LAL. All patients experienced an incident-free postoperative period.
The LAL procedure performed in this study using 1444-nm Nd:YAG laser appears to be a very effective/comfortable outpatient solution to the problem for patients. It has proven a safe procedure, and all subjects in the study experienced a significant clinical improvement regarding their pseudogynecomastia, with a decrease in breast volume and visible skin contraction.
Traumatic tattoos can be treated with several methods, including mechanical and chemical devices. However, they are rarely used due to the high risk of permanent side effects such as scarring and ...depigmentation. Recently, laser devices, especially the Q‐switched (QS) laser and the pulsed dye laser (PDL), applied in combination, have achieved complete clearance of the lesions without any risk of side effects. Herein, we reported three cases of traumatic facial tattoos successfully treated with combined PDL and QS Nd:YAG laser.

Abstract
Dermatosis Papulosa Nigra (DPN) is a common skin condition observed in black people and considered a benign epithelial tumor, and more specifically, a particular topographic form of ...seborrheic keratosis. We treated five female patients affected by DPN with 10,600-nm CO2 laser.
We propose the 10,600-nm CO2 laser as a valid therapeutic option in patients affected by DPN, since the treatment is well tolerated, causes no major side effects, and is effective and long lasting.
