An upturned mouth corner is associated with brightness, optimism, and friendliness, whereas a downturned mouth corner not only conveys negative feelings such as sadness, depression, and tiredness, but also makes a person appear years older than they are. Surgical approaches to the correction of a downturned mouth corner can result in predictable and long-lasting results. However, because of their fear of postsurgical scars and long downtimes, many patients are reluctant to undergo surgery involving the mouth corner. As a consequence, minimally invasive procedures have become increasingly popular in recent years. Among these, botulinum toxin type A and injectable fillers play a significant role. The author uses botulinum toxin type A and hyaluronic acid filler injections as complementary procedures for lifting flat or downturned mouth corners in young patients. This method has produced reliable and consistent outcomes without severe complications such as necrosis or infection in over 100 patients, as reflected in high patient satisfaction. The combination of botulinum toxin type A and hyaluronic acid filler provides excellent results in young patients who desire an uplifted mouth corner and are reluctant to undergo surgery.

嘴角上扬通常与开朗、乐观和友好有关，而嘴角下垂不仅传达出悲伤、沮丧和疲惫等负面情绪，还会让人看起来比实际年龄更大。手术矫正嘴角下垂可以获得可预测且持久的效果。然而，由于许多患者担心术后疤痕和长时间恢复期，他们不愿意接受涉及嘴角的手术。因此，近年来微创治疗越来越受欢迎。其中，A型肉毒毒素和注射用填充物在治疗嘴角下垂中发挥着重要作用。作者使用 A 型肉毒毒素和透明质酸填充剂注射作为提升年轻患者平坦或下垂嘴角的辅助治疗方法。该方法在 100 多名患者中没有出现严重并发症（如坏死或感染），结果可靠且一致，患者满意度高。对于那些希望提升嘴角但又不愿意接受手术的年轻患者，A型肉毒毒素和透明质酸填充剂的联合应用可获得极佳的效果。临床问题/证据水平：治疗性，V。
