The search for nonsurgical cosmetic procedures has increased considerably in recent years. A new injection technique, using vector direction, has shown good results in improving facial aesthetics but to date has only been performed with hyaluronic acid which can be associated with a risk of vascular complications. Therefore, in clinical practice, it would be interesting to assess this technique with a liquid product already widely used in the facial region, and at the same time bring the same aesthetic benefits, but with greater durability than hyaluronic acid.
To investigate the improvement of facial morphology in patients with facial flaccidity submitted to the vector technique using poly-L-lactic acid (PLLA) (Sculptra; Galderma, Lausanne, Switzerland).
Here we report the outcomes of three cases of female patients, aged between 41 and 55 years, seeking improvement of facial flaccidity. In each patient, PLLA was applied in the posterior temporal region as a bolus, in three points, with a 2-mL injection in the upper region, 1.5mL in the midpoint, and 1.5mL at the bottom point. Each of the three patients showed an improvement in face morphology, with concomitant improvement in the support and stretching of the face and improvement in skin sagging in the upper, middle, and bottom regions.
The vector technique with PLLA is a viable alternative for the treatment of patients with facial skin flaccidity, providing harmonious and progressive improvement in the face morphology.
近年来，对非手术美容程序的需求大幅增加。一种新的注射技术，即采用矢量方向，在改善面部美学方面已显示出良好效果，但迄今为止仅使用透明质酸进行，而透明质酸可能存在血管并发症风险。因此，在临床实践中，使用一种已在面部区域广泛使用的液体产品评估该技术将很有意义，同时带来相同的美学益处，但比透明质酸具有更高的持久性。
研究使用聚左旋乳酸（PLLA）（塑然雅；高德美，瑞士洛桑）的矢量技术对面部松弛患者面部形态的改善情况。
在此我们报告3例年龄在41至55岁之间寻求改善面部松弛的女性患者的治疗结果。在每位患者中，将PLLA作为大剂量注射剂注射到颞后部区域的三个点，上部区域注射2毫升，中点注射1.5毫升，底部点注射1.5毫升。三位患者均显示面部形态得到改善，同时面部的支撑和拉伸得到改善，上、中、下区域的皮肤松弛也得到改善。
使用PLLA的矢量技术对于治疗面部皮肤松弛患者是一种可行的选择，可使面部形态得到和谐且渐进的改善。
