背景:鱼纹(SD),或者妊娠纹,是一种常见的皮肤问题,具有心理影响和美容问题,尤其是对女性来说,患病率高于男性。这项研究评估了使用Rigenera®技术管理SD的单次自体微移植治疗(AMT®)的有效性和安全性。
方法:这项单中心研究包括10名年龄在24至65岁之间的健康女性,Fitzpatrick-GoldmanI-IV型皮肤,在臀部/大腿有可见的SD。每个主体充当自己的控制。治疗程序(微针+AMT)和对照程序(不治疗)在对侧的臀部/大腿进行,靶向匹配和配对SD。微米化使用Dermapen®进行,配备32个针头设置在1.5毫米的针头长度。AMT程序包括用2.5毫米的真皮冲头从乳突毛发区提取活检,然后使用Rigeneracons在生理盐水溶液中解聚活检。然后使用30G4毫米针头皮内注射分解的微型移植物,注射点之间保持1厘米的距离,覆盖整个标记的治疗区域。
结果:在治疗区域,术后3个月与术前相比,观察到以下变化,均具有统计学意义(P≤0.05):(a)皮肤粗糙度显着降低(Ra,-15.9%;Rz,-22.6%),皮肤亮度(-2.0%),和蓝绿色分布(-10.6%);(b)皮肤微循环最大值显着增加(240.1%),皮肤水合作用(+71.2%),皮肤弹性(+216.5%),皮肤密度(+34.3%),蒙皮厚度(+26.0%),和皮下组织厚度(+29.9%)。此外,对于上述每个参数,与3个月时的微针相比,AMT手术的改善显著(P均≤0.05).
结论:使用Riggenera技术的AMT程序导致健康女性3个月后SD外观的显着改善。
这是一项用于管理SD的自体微移植技术(AMT)程序的研究。通常称为妊娠纹的条纹(SD)是由皮肤过度拉伸引起的皮肤上的可见线性疤痕。它们是非常常见的情况,尤其是女性,引起美容关注和心理不适。研究中包括10名患有SD的健康女性,每个受试者充当自己的对照。在臀侧/大腿的对侧上的匹配和配对的SD被鉴定用于治疗和对照。在确定的治疗区域,皮肤最初被微针损伤以增强再生,然后皮内注射分解的自体微移植物。从乳突毛发区提取用于AMT程序的微型移植物,并使用Rigeneacons在生理盐水溶液中分解。在控制区,未进行治疗。在手术后1个月和3个月使用几种经过验证的方法评估AMT程序的功效。AMT手术三个月后,观察到皮肤水合作用显着增加,弹性,密度,和厚度,以及皮下厚度和微循环最大值与治疗区域的术前相比。皮肤粗糙度也显著降低,皮肤亮度,和蓝绿色分布在3个月在治疗区域。对于这些参数中的每一个,与仅使用微针相比,使用AMT手术在3个月时观察到的改善显著更高.我们表明,使用Riggeneria技术的单个AMT程序在SD的管理中很有用。
BACKGROUND: 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).
CONCLUSIONS: The AMT procedure using Rigenera technology resulted in an noticeable improvement in the SD appearance after 3 months in healthy women.
This was a study of the Autologous Micrografting Technology (AMT) procedure for management of SD. Striae distensae (SD) commonly known as stretch marks are visible linear scars on the skin arising from excessive stretching of the skin. They are a very common condition, especially in women, causing cosmetic concern and psychological discomfort. Ten healthy women with SD were included in the study and each subject acted as their own control. Matched and paired SD on contralateral sides of the glutes/thighs were identified for treatment and control. In the area identified for treatment, the skin was initially damaged by microneedling to enhance regeneration, followed by intradermal injection of disaggregated autologous micrografts. The micrografts for the AMT procedure were extracted from the mastoid hair zone and disaggregated in physiological saline solution using the Rigeneracons. In the control area, no treatment was performed. The efficacy of the AMT procedure was assessed at 1 and 3 months post-procedure using several validated methodologies. Three months after the AMT procedure, a significant increase was observed in skin hydration, elasticity, density, and thickness, as well as in hypodermis thickness and microcirculation maximum value compared with pre-procedure in the treated area. There also was a significant reduction in skin roughness, skin luminance, and blue-green color distribution at 3 months in the treated area. For each of these parameters, the improvement observed at 3 months was significantly higher with the AMT procedure compared with only microneedling. We showed that a single AMT procedure using Rigenera technology is useful in the management of SD.
