文献解读:交联透明质酸钠凝胶联合非剥脱性点阵激光用于皮肤年轻化治疗的有效性与安全性 !

随着年龄的增长,我们的皮肤会逐渐老化,变得松弛、暗沉,这些变化主要与真皮层细胞(特别是成纤维细胞)再生细胞外基质的合成能力下降有关。此外,表皮层变薄和基底膜扁平化也是导致皮肤老化的原因。皮肤光老化后,主要的治疗目标应是改善肤色与肤质、增加皮肤紧致度以及减少皱纹。临床上主要的治疗方法包括填充剂注射、肉毒毒素注射、美塑疗法、激光、射频和强脉冲光(IPL)治疗。在皮肤年轻化治疗中,与单一疗法相比,联合治疗往往能取得更好的效果

Adriana Ribé,et al. 发表在《J Cosmet Laser Ther》期刊上的一项研究证实了透明质酸钠注射联合激光用于皮肤年轻化治疗的良好效果[1]。该研究共纳入9名女性患者,年龄42-62岁,皮肤光分型Ⅱ-Ⅳ级,均出现光老化现象(轻中度皱纹、轻中度皮肤松弛和日光性着色斑)。给予患者真皮深层注射交联透明质酸钠凝胶瑞蓝·唯瑅™,随后采用Affirm™激光照射治疗,每2-4周重复治疗一次,共4个疗程。研究者分别于治疗前、治疗后一个月及治疗4个疗程后对治疗区域进行拍照和活检以评估疗效。患者在第2和第4次治疗后采用总体美观改善量表(0:差;1:无变化;2:改善;3:明显改善;4:极大改善)进行自我评估。

研究结果显示:与治疗前相比,接受瑞蓝·唯瑅™联合Affirm™激光治疗后,治疗区域皮肤的外观和肤色变得更加均匀,色素斑显著减少,且皮肤变得更有光泽。同时观察到皮肤细纹(中度),皮肤质地和皮肤紧致度(轻中度)也有所改善。第2、4次治疗后,总体美观改善量表评估结果显示,所有患者都认为自己的皮肤状况得到改善,其中,67%(6例)的患者认为得到明显改善,22%(2例)得到一般改善,11%(1例)得到极大改善(见图1)。

此外,对皮肤组织活检后发现,接受瑞蓝·唯瑅™联合激光治疗后,患者的皮肤细胞结构、皮肤中的胶原蛋白和弹性纤维也均得到了改善。与治疗前相比,治疗后的皮肤更富营养化,较治疗前具有更多的角质细胞层和更好的角质形成细胞极性。

研究还观察到,在联合治疗前,皮肤乳头状真皮层中原有的疏松和致密的网状结构(主要是III型胶原蛋白)已部分丧失,取而代之的是致密的纤维化外观(图2A)。瑞蓝·唯瑅™联合激光治疗4个疗程后,可立刻在乳头状真皮层上观察到具有精细编织网和疏松状外观的胶原蛋白,同时观察到胶原纤维的数量和厚度增加。与立刻治疗后相比,治疗后1个月观察到了相似的结果(图2B)。

研究中唯一观察到的不良事件为水疱形成,于2周内恢复,未残留疤痕。

瑞蓝·唯瑅™是一种注射用交联透明质酸钠凝胶可通过刺激细胞外基质(ECM)改善皮肤衰老现象,使肌肤快速恢复活力[2,3]。其效果源于交联透明质酸结合水的能力[4]。透明质酸(HA)是稳定ECM的重要成分,可结合大量水,且在水合稳态中起重要作用。HA不仅是重要的组织结构成分,还具有一定功能性,与细胞外物质输送(组织中电解质、营养物质和分解产物的扩散)和免疫系统活性有着密切关系[5]。

瑞蓝·唯瑅™适用于需要改善皮肤外观的人群,对于紫外线受损严重的皮肤,联合治疗或许是更优的选择。激光治疗是针对紫外线受损皮肤的有效治疗方案,有研究者推荐,在激光治疗前行交联透明质酸注射可以提高皮肤对激光热刺激的反应性,从而获得更好的治疗效果[5]。

Adriana Ribé,et al.研究结果也证实,对比单纯的激光治疗,激光治疗前行瑞蓝·唯瑅™注射可使肌肤更快恢复水润和弹性。该研究还发现,激光主要作用于皮肤表皮层和浅表真皮层,而瑞蓝·唯瑅™主要作用与中-深层的真皮层,将两者结合,皮肤全层均可得到有效改善。

 

以上案例说明,瑞蓝·唯瑅™联合激光治疗可有效实现肌肤年轻化,减少皱纹,提升肌肤紧致度,改善肤色和肤质,为皮肤年轻化治疗提供了有效方案。
