Definitions

  • Various embodiments of the present invention relate to a needle assembly for face lifting.

  • Facial lifting is a procedure that inserts a thread with a small bump, such as a rose thorn, into the skin and pulls out the wrinkles.
  • Threads used for face lifting generally use medical threads that are harmless to the human body. Face lifting implants these threads under the skin, pulling the soft tissue evenly, pulling out loose skin and tightening the loose skin. In addition to improving wrinkles, facial lifting can catch sagging skin and sagging jaw lines, thereby eliminating wrinkles such as forehead wrinkles and nasolabial folds.

That is, various embodiments of the present invention form an anchor having a width larger than the width of the body at the end of the lifting seal, so that the yarn inserted into the skin is anchored firmly to the skin.
  • various embodiments of the present invention allow anchoring to the skin more firmly by forming additional anchoring structures in the anchors, or by further forming end extensions and / or tip extensions.
