[PMID: 38890781 DOI: 10.1002/lsm.23817] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2024] [Revised: 05/29/2024] [Accepted: 06/01/2024] [Indexed: 06/20/2024]
Abstract
BACKGROUND Skin rejuvenation is a widely sought-after goal, prompting advancements in laser technology for noninvasive and effective treatments. Ablative lasers, in particular, have evolved to address diverse skin concerns, with fractional ablative lasers offering better-tolerated outcomes. The introduction of a novel ablative Thulium pulsed laser, based on Thulium-doped Yttrium aluminum Perovskite (Tm:YAP) crystal, delivers precise and controlled skin rejuvenation by allowing customization of ablative microcolumns. METHODS A pilot in vivo study was conducted on the abdominal skin of a live female pig. Using the Laser Team Medical (LTM) prototype laser, treatments were administered with varying coagulation settings (minimal and maximum) and energies (32, 80, 120, and 160 mJ per microcolumn). Biopsies were harvested, fixed, and stained for subsequent analysis. The penetration depth and width of the microcolumns were evaluated. RESULTS Low coagulation settings produced ablative microcolumns with thermal affected zones of 160 µm width, while high coagulation settings resulted in wider zones of 400-530 µm. The ablation cavities' width was estimated to be less than 100 µm in both settings. The novel 1940 nm pulsed laser demonstrated superior microcolumn properties, offering potential advantages such as shorter downtime and increased efficacy compared to existing fractional ablative lasers. CONCLUSION This study presents encouraging preliminary results regarding the efficacy and safety of the first ablative 1940 nm pulsed laser. The results show ablative microcolumns thinner than the counterpart devices, showing the device safety and potential higher efficacy along with short downtime. The LTM novel ablative 1940 nm pulsed laser holds immense potential for enhancing skin rejuvenation treatments due to its superior microcolumns properties. The versatility of this laser can open new treatment procedures and may extend to different areas of dermatology.

Abstract
Ultrasonography (US) has emerged as a pivotal tool in Dermatology since its inaugural use in 1979. Its evolution encompasses technological advancements, higher frequencies, and diverse applications in clinical, surgical, and research aspects. The discussion centers on its crucial role in assessing skin aging through various parameters such as skin thickness, subepidermal low echogenicity band (SLEB) characterization, and echogenicity assessment. This analysis can help guide interventions in a more personalized manner for each patient and assess the effectiveness of cosmetics and procedures. Despite its widespread utility, challenges persist, including discrepancies in research outcomes, operator dependence, inability to detect minute lesions, and measurement variations throughout the day. Combining US with complementary methodologies is advocated for a better understanding of skin aging in vivo. The cost-effectiveness and non-invasiveness of the US emphasize its promising future in dermatology, but ongoing research remains imperative to enhance its accuracy and expand its applications.

A systematic review and meta-analysis of efficacy, safety, and satisfaction rates of laser combination treatments vs laser monotherapy in skin rejuvenation resurfacing. Lasers Med Sci 2023; 38:228. [PMID: 37776370 DOI: 10.1007/s10103-023-03856-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2023] [Accepted: 08/11/2023] [Indexed: 10/02/2023]
Abstract
Laser therapies have been well-established in ameliorating skin-aging consequences. This systematic review aims to determine the efficacy, safety profile, and satisfaction rates of laser combination therapies on skin rejuvenation resurfacing. A systematic search was performed in four major databases up to September 2022. Skin rejuvenation studies were eligible comprising at least one laser combination arm, inclusive of all laser types (ablative or non-ablatives), and one monotherapy arm selected from one of the combined modalities. Studies combining one laser modality with radiofrequency (RF) or intense pulse light (IPL) were also assessed. Trials that did not encompass a monotherapy control arm were evaluated independently as single-arm studies. Eighteen clinical trials recruiting 448 cases were included after screening. A total of 532 nm KTP + 1064 nm Nd:YAG and 2940 nm Er:YAG + Nd:YAG were the two most utilized laser combinations and exerted higher improvements and milder adverse events, compared to their monotherapy in most studies. Combining CO2 with rhodamine-IPL or gallium arsenide laser increased efficacy and satisfaction and brings about faster skin recovery time. Augmenting CO2 + RF did not increase improvement vs CO2 laser alone but prolonged skin erythema. Our meta-analysis revealed the pooled prevalence of quartile improvement rates as 0%, 28%, 40%, 27% in laser combination group, and 0%, 9%, 31%, 17% in laser monotherapy group, respectively. The satisfaction within each quartile category was 39%, 25%, 15%, 7% in laser combination and 20%, 25%, 16%, 17% in laser monotherapy, respectively, suggestive of the higher efficacy and satisfaction of laser combination group. The pain scores were lower in laser combination group than monotherapy (4.8 ± 1.18 vs 7.18 ± 0.7, converted on a scale of 0 to 10). Post-laser skin erythema lasted less longer in the combination group (12.8 vs 15.24 days). Laser combination therapies were discovered to be superior to their monotherapies in terms of clinical improvement rates, diminished adverse events such as pain and erythema and patients satisfaction rates. Due to paucity of high-quality reportings, additional trials are warranted to corroborate these results.

Efficacy of fractional CO 2 laser in combination with stromal vascular fraction (SVF) compared with fractional CO 2 laser alone in the treatment of burn scars: a randomized controlled clinical trial. Stem Cell Res Ther 2023; 14:269. [PMID: 37742019 PMCID: PMC10518108 DOI: 10.1186/s13287-023-03480-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2023] [Accepted: 08/29/2023] [Indexed: 09/25/2023] Open
Abstract
BACKGROUND The appearance of skin scars is known as one of the main side effects of skin burns. Stromal vascular fraction (SVF), as a rich source of cell populations with tissue regeneration properties, plays an important role in the healing of skin lesions. Fractional CO2 lasers have occupied a special place in treating skin lesions, particularly skin scars, since their introduction. Our study aimed to compare the combination of SVF and fractional CO2 laser with fractional CO2 laser alone in the treatment of burn scars. METHOD This double-blind clinical trial study was conducted on ten patients with burn scars that were treated three times with a fractional CO2 laser at site of burn lesions, and one of the two areas studied was randomly injected with SVF. Two months after completion of the procedure, patients' scars were assessed using the Vancouver scar scale (VSS), biometric criteria, and physician and patient satisfaction ratings. RESULTS The results confirmed a significant improvement in VSS, cutometry, R7 criteria, complete density sonography, and skin density sonography in the fractional CO2 laser-treated group. The VSS criteria, epidermal thickness sonography, complete density sonography, and skin density sonography in the group treated with the combination of fractional CO2 laser and SVF also showed significant improvement. The VSS criteria and melanin index of Mexameter in the group treated with SVF in combination with fractional CO2 laser were significantly better than the group treated with fractional CO2 laser alone. Also, physician and patient satisfaction in the group treated with SVF injection in combination with fractional CO2 laser was significantly higher than the other group. CONCLUSION The results confirm the efficacy of SVF injection in combination with fractional CO2 laser in the treatment of burn scars and can be considered as a treatment option for better management of these lesions. TRIAL REGISTRATION The study protocol was retrospectively registered at Iranian Registry of Clinical Trials with code: IRCT20210515051307N1, Registration date: 2021-11-14, URL: https://www.irct.ir/trial/56337 .

Abstract
The aim of this study is to compare needling (RF-needling, meso-needling, micro-needling) and ablative fractional lasers (CO2, erbium-YAG) in the treatment of atrophic and hypertrophic scars in a systematic review. The database was searched, and 10 articles were selected that were relevant in terms of content, topic, and purpose and met the inclusion criteria. Of all the articles reviewed in this study, there were 2 randomized split-face trials (20%), 1 controlled nonrandomized trial (10%), 1 controlled randomized phase III clinical trial (10%), 1 prospective trial (10%), 1 prospective nonrandomized open-label trial (10%), and 1 randomized comparative trial (10%), with the type of study not reported in 3 articles. We used Endnote X8 to review the articles and extract data. After review, the studies were analyzed and categorized. No statistically significant difference was found between the two methods, laser and micro-needling, in the treatment of atrophic and hypertrophic scars in 60% of the articles studied, and both showed significant improvement (70% or more improvement to complete response). Significant improvement was noted in 20% of the studies reviewed for the laser and micro-needling treatment methods. The results of this study show that needling and ablative fractional lasers are tolerable and safe procedures with no significant difference in the treatment of skin scars in sixty percent of the studies.
