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
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
The aims of this study were to characterize and to compare the structural alterations of collagen and elastic fibers in the abdominal stretch marks of patients submitted to intralesional and per quadrant (region close to stretch marks) Platelet-Rich Plasma (PRP) treatment, as well as, to establish the possible mechanisms of action of this treatment involving toll-like receptors (TLRs) signaling pathways and growth factors. Incisional biopsies were collected from abdominal stretch marks with a 2 mm diameter punch in female patients, at the beginning of treatment, after 6 and 12 weeks of treatment, and submitted to morphological analyzes of elastic and collagen fibers, and immunohistochemistry for TLRs signaling pathways and growth factors. Our results demonstrated PRP per quadrant treatment was most effective in reducing the area of the abdominal stretch marks, with consequent stimulation of the synthesis and remodeling of collagen and elastic fibers. Also, PRP per quadrant treatment promoted an increase in TLR2 and TLR4 immunoreactivities, with consequent increase in TNF-α, VEGF and IGF-1. Based on the current findings, PRP constitutes a promising therapeutic approach in patients with stretch marks, since it promoted modulation of inflammatory cytokines and growth factors, with consequent remodeling of extracellular matrix, culminating with tissue improvement.

Abstract
INTRODUCTION Stretch marks are common atrophic dermal scars with significant physical and psychological effects. Therefore, there is a need for effective cosmetics and procedures for stretch mark treatment. This study aimed to evaluate the efficacy and safety of a novel treatment for stretch marks that is made up of topical formulations containing beta-glucan combined with nanofractional radiofrequency. METHODS This randomized, blinded control trial enrolled 64 Chinese women aged 20-45 years at > 6 months after delivery with obvious white or silver abdominal stretch marks. Participants were randomly allocated to group A (blank group), group B (topical product group), group C (product combined with nanofractional radiofrequency), and group D (vehicle combined with nanofractional radiofrequency). The stretch mark width, skin elasticity, skin color, skin thickness, and collagen density were noninvasively measured. Two trained assessors evaluated the severity, color, outline, and relaxation of the striae. RESULTS Group C showed the best treatment efficacy, with no adverse effects observed during the study period. CONCLUSION Our findings indicate that stretch mark treatment using topical formulations containing beta-glucan, combined with nanofractional radiofrequency plus magnetic nanofractional radiofrequency, is tolerable and effective.

Abstract
Authors present a study about the contraction forces observed in striae distensae fibroblasts (SMF) in a collagen scaffold. Collagen lattices were used to study the mechanical behavior of SDF within the collagen matrix compared to the lattices produced using the healthy skin derived fibroblasts (NSF). A Forcebox device was used to measure the contractile forces. Striae Rubrae fibroblast's contractile force was by 28% greater than that generated by the NSF and striae albae fibroblasts (P<0.05). Anomalies and especially differences in forces generated by SMF were observed through all our experiments. These findings complete and corroborate the results and information published in our previous studies.

Abstract
INTRODUCTION Striae distensae (SD) appear clinically as parallel striae, lying perpendicular to the tension lines of the skin. SD evolve into two clinical phases, an initial inflammatory phase in which they are called "striae rubrae" (SR) and a chronic phase in which they are called striae albae (SA). Fibroblasts seem to play a key role in the pathogenesis of stretch marks. This study was aimed at describing and analyzing stretch marks-derived fibroblasts (SMF), the differences between SR- and SA-derived fibroblasts (SRF, SAF), testing two treatments in vitro (sodium ascorbate and PrP) on SAF. MATERIAL AND METHODS To characterize the SMF, the expression of alpha smooth muscle actin (alpha SMA) was investigated. Type I collagen expression was measured in SAF, before and after adding different PrP concentrations and sodium ascorbate in the culture medium. Results were processed through statistical analysis models using the Student's t-test. RESULTS A significant increase in alpha SMA (P <0.001) was observed in SRF. SAF treated with PrP and sodium ascorbate showed a resumption of their metabolic activity by an increase in collagen type I production and cell proliferation. After 24 h of incubation with PrP 1% and PrP 5% + sodium ascorbate, cell viability was increased by 140% and 151% and by 156 and 178% after 48 h, respectively, compared to the control. CONCLUSION Our study shows that a biologically mediated improvement in SMF metabolic activity is possible. Our promising results require further trials to be able to confirm the reproducibility of this combined treatment, particularly in vivo.

Abstract
Background Stretch marks are linear scars that result from elastic fiber destruction. They usually occur as the consequence of rapid change in the body mass (weight gain and loss, pregnancy, weightlifting), long‐term steroid use, or endocrinopathies. Treatment is challenging and mainly based on topical and procedural therapies, although the standard of care is still under debate. Purpose To evaluate the efficacy and tolerance of a topical oil formulation of plant extracts and vitamins on the aesthetic improvement of stretch marks and xerosis. Materials and methods Fifty male and female patients, aged between 14 and 45 years, with stretch marks referring at the University Hospital Federico II, Naples, were enrolled between March and November 2019. Topical application of plant extracts and vitamin‐rich oil was performed twice daily on affected skin for 4 months. Patients were monitored at baseline (T0), and at two‐month (T1) and 4‐month (T2) follow‐ups, through clinical and dermoscopic assessment, confocal microscopy, cutaneous ultrasound, MoistureMeterEpiD, and X‐Rite spectrocolorimeter. Primary endpoints were as follows: 70% clinical improvement of stretch marks and 3‐point decrease in clinical score from baseline to T2. Secondary endpoints were as follows: change in the T0 parallel pattern of collagen fibers at confocal microscopy, cutaneous thickness increase at ultrasounds, cutaneous hydration increase at MoistureMeterEpiD, erythema reduction at X‐Rite spectrocolorimeter, and safety and adverse events (AEs). Results At 4‐month follow‐up, stretch marks improved objectively and subjectively in all patients (p < 0.001). In detail, there was a 29% and 71% improvement in clinical appearance of stretch marks at T1 and T2, respectively, as documented dermoscopically and by the 3‐point reduction in the assessor's mean clinical score at each follow‐up visits [from 8.1±0.7 at baseline to 5.7±1.0 at T1 and 2.3 ±0.5 at T2 (p < 0.001)]. Erythema decreased by 15% and 30% and in parallel hydration increased by 25% and 71%, at T1 and T2, respectively (p < 0.001). At T2 confocal microscopy of stretch marks, dermal collagenous fibers assumed casual disposition with reticular pattern and refractivity, as signs of collagen remodeling and neocollagenesis, and also the T2 cutaneous ultrasound revealed increased epidermal thickness and decreased dermal hypoechogenicity as for a higher skin hydration. Conclusion Our study showed that a topical oil formulation rich in plant extracts and vitamins appears to be effective and safe in treating stretch marks and xerosis.

Abstract
Background Striae gravidarum (stretch marks) are considered the most common connective tissue/skin change in pregnancy. Though not a health issue they can affect women in different ways, for example, cause stress or be an aesthetic or cosmetic concern. Many women use one or more of the commercially available products to try and prevent their development during pregnancy despite the fact that that there is a lack of high-quality evidence to support their use. There is a dearth of studies on the prevention of striae gravidarum and large, robust trials are lacking. Until such time as more products are investigated, much of the knowledge remains anecdotal. This pilot study will evaluate the feasibility of conducting a study to evaluate the effectiveness of a commercially available moisturising oil compared to no treatment for the prevention and reduction in severity of striae gravidarum. Methods The definitive study will be a randomised controlled trial to evaluate the effectiveness of a moisturising oil (commercially available moisturising oil) compared to no treatment for the prevention and reduction in severity of striae gravidarum. This protocol is for a pilot randomised trial to evaluate the feasibility of conducting such a study. The pilot study will be a two-arm, unblinded, pragmatic parallel randomised trial with a 1:1 randomisation ratio between control and intervention groups. Women in the intervention group will be asked to apply a moisturising oil to their abdomen during pregnancy, while women in the control group will not use any treatment. It is proposed to recruit 20 primigravida, who are 12–16 weeks pregnant from an Irish Maternity Hospital, in each arm to assess the feasibility of running such a trial. Discussion This pilot trial will evaluate the feasibility of conducting the main study to evaluate the effectiveness of a moisturising oil (commercially available moisturising oil) compared to no treatment for the prevention and reduction in severity of striae gravidarum. It will potentially initiate the generation of high-quality evidence to guide women in their choice of anti-stretch mark product. Trial registration ISRCTN Registry, ISRCTN76992326.
