Abstract: Objective To investigate the efficacy of poly (L-lactic acid) application in the rejuvenation of hands, and to analyze the safety of its application. Methods two subjects with aging problems of the hands were given subcutaneous injections of poly-L-lactic acid for hand filling improvement treatment, a detailed protocol of improving treatment was developed and treated, the status of hand improvement in subjects was followed up after treatment, and standardized hand photographs were taken as a contrast basis. Results after 2 month of young onset hand repair surgery on the two propositi, the veins and prominence of the bones of the hand improved significantly in the two propositi, the darker skin complexion state improved, and the collagen content of the hand improved, with gradual fullness of the fingers in subject 1. Three months after the young onset repair surgery, the skin quality of the hand improved significantly more finely in subject 2, and the darker skin complexion problem had largely disappeared, with the bones remaining intact in the two propositi, The venous prominence problems had largely disappeared, the collagen content of the hands had improved significantly, the finger morphology of patient 1 and the problems of dark finger joints had all improved significantly, and none of the 2 subjects had related complications, and the 2 subjects had high satisfaction with the young treatment of polylactic acid hand.

唇部作为面部的一个重要美学单位,在面部特征中发挥着重要影响。基于唇部美学考虑,年轻的唇部状态应是莹润饱满,唇红缘线条流畅、清晰,唇体对称且无皱纹,口角微上翘[1]。而随年龄增长及外部因素的影响,唇部会逐渐呈现老化的表现,如因容量流失所致的唇红变薄、唇红缘模糊、上唇人中延长、口角下垂及口周皱纹增加等[2]。唇部年轻化治疗的目标是实现唇红容量恢复、唇纹填充、口角提升以及口周皮肤年轻化[3]。
