泪沟It is a concave groove that appears from the inner corner of the eye on the nasal side of the lower eyelid. It is formed due to soft tissue atrophy and drooping. The concave is obviously different from the surrounding skin, which affects the appearance of the face. This phenomenon occurs in many people, and some people even extend to the cheeks.

泪沟分为年轻型和老年型，年轻型是因为眼眶下缘的软组织萎缩、下垂导致的；老年型则是因为面部老化松弛、皮下脂肪减少导致的，泪沟的存在不仅影响面部美观，也会显得憔悴和苍老，通过一定的医学手段，如玻尿酸注射填充、自体脂肪填充等，可以有效地改善泪沟问题,日常的皮肤保养也是预防和减轻泪沟问题的重要措施之一。
