The present disclosure relates to a suture which, being inserted into skin, can lift skin and thus improve or remove skin wrinkles. The suture includes a through-hole which allows formation of new skin tissue and thus provides a (semi)permanently lasting effect of lifting skin and improving or removing wrinkles and has a shape of a sheet whose length is longer than its width.The present disclosure also relates to a suture which, being inserted into skin, can expand overall skin volume by inducing formation of new skin and adhesion between skin layers.The present disclosure also relates to a kit including the suture for lifting skin, which can expand overall skin volume.本發明是關於一種能插入皮膚中以拉提皮膚並從而改善或去除皮膚皺紋的縫線。該縫線包括通孔,該通孔可供形成新皮膚組織且從而提供(半)永久持續的皮膚拉提作用並改善或去除皺紋,及該縫線具有長度比寬度要長的薄片形狀。本發明亦關於一種能插入皮膚中以誘使形成新皮膚並使皮膚層之間產生黏附作用而擴張皮膚總體積的縫線。本發明亦關於一種套組,該套組包含用於拉提皮膚的縫線,該縫線能擴張皮膚總體積。10‧‧‧縫線100‧‧‧通孔
