Abstract
Supraphysiological stretches are exploited in skin expanders to induce tissue growth for autologous implants. As pregnancy is associated with large levels of sustained stretch, we investigated whether skin growth occurs in pregnancy. Therefore, we combined a mechanical model of skin and the observations from suction experiments on several body locations of five pregnant women at different gestational ages. The measurements show a continuous increase in stiffness, with the largest change observed during the last trimester. A comparison with numerical simulations indicates that the measured increase in skin stiffness is far below the level expected for the corresponding deformation of abdominal skin. A new set of simulations accounting for growth could rationalize all observations. The predicted amount of tissue growth corresponds to approximately 40% area increase before delivery. The results of the simulations also offered the opportunity to investigate the biophysical cues present in abdominal skin along gestation and to compare them with those arising in skin expanders. Alterations of the skin mechanome were quantified, including tissue stiffness, hydrostatic and osmotic pressure of the interstitial fluid, its flow velocity and electrical potential. The comparison between pregnancy and skin expansion highlights similarities as well as differences possibly influencing growth and remodeling.

Abstract
BACKGROUND The appearance of striae gravidarum (SG) during pregnancy is a common problem. The most common SG are abdominal striae, which can cause the greatest sequelae after pregnancy, and in the long term. There are several solutions to prevent and treat these striae, but not all are completely effective, and not without side effects. AIMS The aim of this study was to evaluate the effectiveness of a treatment that applies an electromagnetic field under vacuum (V-EMF therapy) on the abdominal SG. METHODS A retrospective analysis was conducted on the medical records of 26 women affected by abdominal SG and treated with V-EMF therapy. The results were evaluated using two different 5-point Likert Scales: one administered to the treated subjects to evaluate their satisfaction, and one to the doctors who performed the treatment, to evaluate the improvement of the striae. The presence of side effects, and the effects of sun exposure after treatment were also considered. RESULTS Only two treated subjects rated their level of satisfaction with a Score III on the Liker Scale. Everyone else expressed higher levels of satisfaction. Only one doctor rated the improvement of the striae with a Liker scale score of III. All the others reported greater improvements. No discomfort or side effects were noted either during the individual treatment sessions, or at the end of the treatment. The striae showed a newfound ability to tan. CONCLUSIONS V-EMF therapy proves to be a valid, safe, and effective treatment modality for SG.

Abstract
BACKGROUND Striae distensae (SD) are cutaneous lesions that are caused by hormones or mechanical stress leading to rapid expansion of skin. Therefore, SD are now a cosmetic concern. However, improving SD is notoriously difficult. Among different treatments, energy-based devices (EBDs) are much more effective and controllable. OBJECTIVE The aim of this review was to determine the most effective type of EBD for improving the appearance of striae. MATERIALS AND METHODS The study was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The population comprised patients suffering from striae. Different types of EBDs used to improve striae were compared. The primary outcome of the reduction in the width of striae was evaluated. A random-effects model was performed. The means and standard deviations were extracted. RESULTS Eighteen randomized controlled trials were included. The network meta-analysis revealed that after a comparison among the 4 types of EBDs, no significant differences were observed in the reduction of striae width. CONCLUSION Radiofrequency, ablative lasers, nonablative lasers, and intense pulsed light are all effective treatments for reducing the striae width. None of them was superior to the others. However, radiofrequency and ablative lasers may have the highest chance of improving the appearance of striae.

Abstract
INTRODUCTION Striae distensae are a permanent skin defect that can affect 50%-90% of the population. The appearance of the changes resembles spindle-shaped skin bands. The skin in this area is wrinkled, thin and looks like a scar. Most often, the changes are found on the skin of the abdomen, buttocks, breasts, thighs, and back. The appearance of striae means that the skin in this area has no hair follicles, sebaceous, and sweat glands. This skin is flabby, not very elastic and, what is very characteristic, the pigmentation of the skin affected by striae is much lower than in healthy skin. Cosmetology in the 21st century is developing very dynamically, new technologies are being developed, new cosmetological devices are being created and combined with treatments that have been known for a long time. Today's science offers hope for people who have struggled with reducing striae for many years and nowadays, nothing is impossible. AIMS The objective of this article is to provide information about cosmetological treatment used to reduce striae. METHODS In this article, we reviewed the published literature, article published in peer-reviewed journals. RESULTS Today's cosmetology offers a wide range of numerous treatments, but the best results are achieved through a synergy of two or more treatments. But we should not forget that we should respond to each customer individually. CONCLUSION The striae are not a problem that should be ignored. The beauty therapist is able to reduce them and help the client to improve the appearance of their skin.

Abstract
INTRODUCTION Striae distensae (SD), linear scars of derma, caused by disproportionate skin stretching, which indicates a cosmetic problem and even endangers individuals' psychosocial health. Microneedling, representing a relatively new procedural therapy, has shown brightening but diverse results in the remedy of SD. Our study systematically investigates and further evaluates the efficacy of microneedling for SD. METHOD This study was conducted following the PRISMA guidelines. According to the preplanned search strategy, four electronic databases were comprehensively searched for eligible clinical controlled studies. Standardized mean difference (SMD) and odd ratio (OR) with 95% confidence intervals were calculated for continuous data and dichotomous data, respectively. RESULTS According to the predetermined criteria, eleven eligible articles of six RCTs and five non-RCTs were included. Concerning clinical improvement, a significant difference was observed in the microneedle radiofrequency treatment subgroup (SMD: 0.57, 95% CI 0.20-0.94, P = 0.003). The pooled result of the second subgroup revealed that microneedling and lasers producing almost comparable effectiveness for treating SD with no significant difference (P = 0.35). The analysis result of the third subgroup of microneedling versus non-laser therapy indicated significant difference at the 5% significance level (SMD:1.01, 95% CI 0.51-1.51, P < 0.0001). With regard to patient satisfaction, the pooled estimate concluded that participants' satisfaction with therapeutic effect between MRF and laser group was comparable (P = 0.26), whereas microneedling exhibited significant superiority than both laser (P = 0.04) and non-laser treatments (SMD: 0.95, 95% CI 0.52-1.38, P < 0.0001). Occurrence of post-inflammatory hyperpigmentation (PIH) was not obvious in microneedling therapy compared to other treatments, and a statistically difference was observed (P = 0.0003). Microneedling treatment caused significant pain compared with laser therapy (P < 0.00001). CONCLUSION This systematic review and meta-analysis has provided initial evidence of the efficacy and safety of microneedling technology for SD.

Abstract
BACKGROUND Striae distensae is a disfiguring atrophic skin condition that impairs the body's aesthetic image. Despite the variety of conducted studies, there is controversy regarding the best modalities. Human mesenchymal stem cells are considered a rich source for scar treatment. Skin needling is among the most efficient and safe aesthetic and therapeutic devices. This study aimed to evaluate the efficacy of the combination of needling and intradermal injection of mesenchymal stem cells compared to skin needling alone for treating striae distensae. METHOD This study was a randomized, double-blind clinical trial involving 10 women aged 18-60. Each striae lesion was divided into two parts, with one side receiving needling and intradermal injection of conditioned medium, while the other side received needling and intradermal injection of normal saline. This treatment was administered in three sessions with three-week intervals. Patients were evaluated before the first intervention and three months after the final session. Three months after the completion of the intervention, patients' lesions were evaluated using biometric criteria, physician evaluation, and patient self-assessment. RESULTS The results demonstrated a significant improvement in dermal and complete thickness and skin density in patients treated with microneedling. All skin ultrasound parameters improved significantly in patients receiving the combination of needling and conditioned medium. When comparing the two groups, significantly higher physician and patient satisfaction was observed in the combination group. However, the comparison of biometric indices improvement wasn't significant between these groups. CONCLUSION The combination of human mesenchymal stem cells with microneedling could be considered a novel effective option for stretch marks.

Abstract
The most common conditions with symptomatic joint hypermobility are hypermobile Ehlers-Danlos syndrome (hEDS) and hypermobility spectrum disorders (HSD). Diagnosing these overlapping connective tissue disorders remains challenging due to the lack of established causes and reliable diagnostic tests. hEDS is diagnosed applying the 2017 diagnostic criteria, and patients with symptomatic joint hypermobility but not fulfilling these criteria are labeled as HSD, which is not officially recognized by all healthcare systems. The 2017 criteria were introduced to improve diagnostic specificity but have faced criticism for being too stringent and failing to adequately capture the multisystemic involvement of hEDS. Herein, we retrospectively evaluated 327 patients from 213 families with a prior diagnosis of hypermobility type EDS or joint hypermobility syndrome based on Villefranche and Brighton criteria, to assess the effectiveness of the 2017 criteria in distinguishing between hEDS and HSD and document the frequencies of extra-articular manifestations. Based on our findings, we propose that the 2017 criteria should be made less stringent to include a greater number of patients who are currently encompassed within the HSD category. This will lead to improved diagnostic accuracy and enhanced patient care by properly capturing the diverse range of symptoms and manifestations present within the hEDS/HSD spectrum.

Abstract
INTRODUCTION Striae distensae (SD), or stretch marks, are a common skin problem having a psychological impact and cosmetic concern, especially for women, in whom the prevalence is higher than in men. This study assessed the efficacy and safety of a single autologous micrografting treatment (AMT®) using Rigenera® technology for the management of SD. METHODS This single-centre study included 10 healthy women between 24 and 65 years of age, with Fitzpatrick-Goldman skin types I-IV, who had visible SD in glutes/thighs. Each subject acted as their own control. The treatment procedure (microneedling + AMT) and the control procedure (no treatment) were performed on contralateral sides of the glutes/thighs, targeting matched and paired SD. Microneedling was carried out using Dermapen®, equipped with 32 needle heads set at 1.5 mm needle length. The AMT procedure involved extracting biopsies from the mastoid hair zone with a 2.5-mm dermal punch, followed by disaggregation of the biopsies in a physiological saline solution using the Rigeneracons. The disaggregated micrografts were then intradermally injected using 30G 4-mm needles, maintaining a distance of 1 cm between injection points, covering the entire marked treatment region. RESULTS In the treated area, at 3 months post-procedure compared to pre-procedure, the following changes were observed, all with statistical significance (P ≤ 0.05): (a) significant reductions in skin roughness (Ra, - 15.9%; Rz, - 22.6%), skin luminance (- 2.0%), and blue-green color distribution (- 10.6%); (b) significant increases in skin microcirculation maximum value (+ 240.1%), skin hydration (+ 71.2%), skin elasticity (+ 216.5%), skin density (+ 34.3%), skin thickness (+ 26.0%), and hypodermis thickness (+ 29.9%). Furthermore, for each of the aforementioned parameters, there was a significantly greater improvement observed with the AMT procedure compared with microneedling at 3 months (all P ≤ 0.05). CONCLUSION The AMT procedure using Rigenera technology resulted in an noticeable improvement in the SD appearance after 3 months in healthy women.

Abstract
Background: A current popular aesthetic problem, especially among younger women, is striae distensae (SD), also referred to as "stretch marks.". Aim: The potential use of the 675 nm laser has been investigated in the treatment of SD. Methods: Patients underwent three sessions of the 675 nm laser with a 1-month interval between sessions. A total of three sessions were performed. The Manchester Scar Scale was used to assess stretch mark changes, and the mean scores related to each parameter at baseline and 6M FU after the last treatment session were measured. A clinical photographic evaluation was performed to show the aesthetic improvement of SD. Results: The patients' treated areas were the abdomen, thighs, buttocks, and breasts. Mean scores related to each Manchester Scar Scale parameter, with their relative percentage change, at baseline and 6M FU after the last treatment session were significantly improved. The total mean Manchester Scar Scale score significantly diminished from 14.16 (±1.30) to 10.06 (±1.32) at 6M FU (p < 0.01). The clinical photographs showed promising aesthetic SD improvement. Conclusions: 675 nm laser therapy demonstrated a good tolerance for the treatment of stretch marks applied to various body areas preventing any discomfort for the patient and with a significant improvement in skin texture.

Abstract
BACKGROUND Available current therapeutics modalities for striae distensae (SD) provide inconsistently effective outcomes. There is ongoing research on innovative treatment modalities to find better treatment solutions. OBJECTIVES To evaluate the efficacy and safety of innovative cold atmospheric plasma (CAP) technology in the treatment of striae distensae. METHODS This study includes twenty-three patients with striae distensae. The body was divided into two halves. One side was randomly treated with CAP biweekly on the same treated side for five sessions with 30 days follow-up after the last session. Another half was left untreated. Efficacy assessment was done using patient and observer scar assessment scale (POSAS), patient satisfaction scales, and Antera 3D® skin imaging system. Safety assessment was evaluated using the visual analog scale (VAS) and adverse effects monitoring. RESULTS Patient and observer scar assessment scale, patient and observer overall opinion score, and patient and observer total score in a summary of all rated characteristics, comparing treated and untreated areas, showed a statistically significant reduction in all parameters after one treatment (*p-value <0.05). Patients rated satisfaction as a great improvement in 52.3%, moderate improvement in 39.1%, extreme improvement in 4.3%, and slight improvement in 4.3%. Adverse effects included small scabs, shallow wounds, and rash. CONCLUSION Cold atmospheric plasma is a safe and effective, innovative treatment modality for striae distensae with minimal side effects.

Abstract
BACKGROUND Keloid (KD) treatment is challenging for both physicians and patients. It can be functional debilitating and psychologically distressing. Available current therapeutics modalities give inconsistently effective results. OBJECTIVES To evaluate the efficacy and safety of innovative cold atmospheric plasma (CAP) technology in the treatment of keloid. METHODS This prospective, randomized control trial, the assessor-blinded trial, includes 18 patients with keloids. The keloid lesion was divided into two halves. One side was randomly treated with CAP technology biweekly on the same treated side for five sessions with a follow-up 30 days after finishing the final treatment. Another half was left untreated as a control. Efficacy assessment using POSAS, VSS, Patients' satisfaction scale, Antera 3D® skin imaging system. The safety assessment using VAS and adverse effects monitoring was completed. RESULTS Objective assessment using Antera 3D® skin imaging system (Miravex, Dublin, Ireland) showed statistically significant improvement (p-value <0.05) on the treated side compared with the untreated side in all parameters, color, melanin, hemoglobin, texture, except for volume. POSAS, patient, and observer overall opinion score, and patient and observer total score in the summary of all rated characteristics, comparing the treated and untreated areas, showed a statistically significant reduction in all parameters after two treatments (*p-value <0.05). VSS showed statistically significant improvement after the second treatment and continued to the last follow-up. Most patients rated satisfaction scales up to 72.2% as moderate improvement, 11.1% as great improvement, 11.1% as slight improvement, and 5.6% as no change. The adverse effect was only a small scab in one patient. CONCLUSION CAP technology could be considered an alternative treatment for keloid offering mild-to-moderate improvement with minimal side effects.

The Alleviating Effect of Lagerstroemia indica Flower Extract on Stretch Marks through Regulation of Mast Cells. MOLECULES (BASEL, SWITZERLAND) 2022; 27:molecules27041274. [PMID: 35209065 PMCID: PMC8877584 DOI: 10.3390/molecules27041274] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/26/2022] [Revised: 02/11/2022] [Accepted: 02/12/2022] [Indexed: 11/17/2022]
Abstract
Striae distensae (SD) or stretch marks are common linear scars of atrophic skin with disintegrating extracellular matrix (ECM) structures. Although fibroblasts contribute to the construction of ECM structure in SD, some studies have reported that mast cell degranulation causes the disruption of ECM in early SD lesions. Lagerstroemia indica flower (LIF) has traditionally been used in India as a diuretic. However, little is known about the effect and molecular action of Lagerstroemia indica flower extract (LIFE) on alleviating SD. This study evaluated the effects of LIFE on mast cell degranulation and the synthesis of ECM components in fibroblasts. LIFE inhibits the adhesion of rat basophilic leukemia (RBL) cells, RBL-2H3 on fibronectin (FN) and the expression of integrin, a receptor for FN, thereby reducing focal adhesion kinase (FAK) phosphorylation. In addition, LIFE attenuated the allergen-induced granules and cytokine interleukin 3 (IL-3) through the adhesion with FN. Moreover, the conditioned medium (CM) of activated mast cells decreases the synthesis of ECM components, and LIFE restores the abnormal expressions induced by activated mast cells. These results demonstrate that LIFE suppresses FN-induced mast cell activation and promotes the synthesis of ECM components in fibroblast, which indicates that LIFE may be a useful cosmetic agent for SD treatment.
