Defining the ideal dimensions and proportions of the human face has been attempted for centuries, popularised in the Renaissance period by artists including Leonardo Da Vinci. The lips are part of the lower third of the face and are central to lower face aesthetics and the overall symmetry of the face. They also place an important part in conveying facial emotions and expressions. Full lips with well-defined Cupid's bow have always been associated with youth and beauty. The approval of hyaluronic acid use for tissue augmentation and the prevalence of social media have caused an exponential increase in lip augmentation procedures (Linkov et al. in Arch Plast Surg 46(3):248-254, 2019), as such researchers and aestheticians have focused on characterising the ideal lips mathematically to help guide clinicians. This narrative review will summarise the available evidence in the literature pertaining to the ideal lips, taking into account age, ethnicity and gender differences. LEVEL OF EVIDENCE III: This journal requires that authors assign a level of evidence to each article.

几个世纪以来，人们一直试图定义理想的人脸尺寸和比例，包括莱昂纳多·达·芬奇在内的文艺复兴时期的艺术家们使这一概念得到普及。嘴唇是脸的下三分之一的一部分，是下面部美学和面部整体对称性的核心。它们对面部情绪和表情的表达也起着重要作用。丰满且唇珠明显的嘴唇一直与年轻和美丽联系在一起。透明质酸在组织填充中的应用得到认可，以及社交媒体的盛行，导致唇部填充手术呈指数级增长（Linkov 等人，Arch Plast Surg 46(3):248-254, 2019），因此研究人员和审美学家专注于用数学方法来描述理想的嘴唇，以帮助指导临床医生。本综述将总结文献中关于理想嘴唇的现有证据，同时考虑到年龄、种族和性别差异。证据级别 III：本期刊要求作者为每篇文章分配一个证据级别。有关这些循证医学评级的完整描述，请参阅目录或在线作者指南 www.springer.com/00266 。
