Topological lines of collagen fibers' orientation in the dermis
Langer's lines
Langer's lines, Langer lines of skin tension, or sometimes called cleavage lines, are topological skin lines drawn on a map of the human body. They are parallel to the natural orientation of collagen fibers in the dermis, and generally parallel to the underlying muscle fibers. Langer's lines have relevance to forensic science and the development of surgical techniques.
