Relaxed Skin Tension Lines
Skin tension lines, also known as Langer's lines or lines of cleavage, are linear clefts in the skin that indicate the direction of orientation of the underlying collagen fibers. If the skin is disrupted parallel to the long axis of the fibers, the wound tends to reapproximate.

Direction of force is along each line. Cuts perpendicular to these lines are thus under greatest tension and most likely to widen.

Langer lines run in the direction of the underlying collagen fibers (least skin tension) and play an important diagnostic role for some exanthematous skin diseases. In the thoracodorsal region, the distribution of the Langer lines gives rise to what is referred to as a 'Christmas tree pattern'.

Borges coined the term 'relaxed skin tension lines' (RSTL) and advised using these lines on the face for surgical excisions. However, on the trunk and limbs, Borges considered RSTL and wrinkle lines together. A small number of cadaver and clinical studies have therefore ended up guiding cutaneous surgery through history.

Skin tension lines reflect internal tension within the skin and are mainly produced by the connective tissue of the dermis, superimposed by external tension.
Biodynamic Excisional Skin Tension Lines for Cutaneous Surgery Semantic Scholar
The concept of skin tension lines is widely attributed to the studies of Langer, who used a round-tipped awl to create defects in cadaveric skin and then observed the elongation of these.
Biodynamic excisional skin tension lines for surgical excisions untangling the science
Skin tension lines are natural lines of tension that occur within the skin as a result of growth and remodeling mechanisms. Researchers have been aware of their existence and their.

Definition This section has been translated automatically. Lines of skin of equal tension in interaction with the muscles. Their course depends on the patient's age, nutritional status, general condition and possibly anatomical peculiarities. In the face, skin tension lines follow the mimic muscles.

Langer's lines, Langer lines of skin tension, or sometimes called cleavage lines, are topological lines drawn on a map of the human body. They are parallel to the natural orientation of collagen fibers in the dermis, and generally perpendicular to the underlying muscle fibers.

Skin tension lines (STLs) are the result of a complex interaction between internal and external factors involving the skin. The intrinsic framework, which consists of elastin and collagen,.

Skin tension lines essentially refer to the direction of maximal skin tension at different body sites. They reflect internal tension within the skin due to connective tissue (e.g. collagen) within the dermis. There are different types of skin tension lines.
Biodynamic excisional skin tension lines for surgical excisions untangling the science The
Skin tension lines are natural lines of tension that occur within the skin as a result of growth and remodeling mechanisms. Researchers have been aware of their existence and their surgical implications for over 150 years.

Researchers have developed a device that in one step can quickly and non-invasively measure skin tension lines, according to an article published online February 5, 2019, in the Elsevier journal Acta Biomaterialia. Human skin exhibits anisotropy largely due to collagen and elastin fiber alignment in the dermis.

Methods: Following studies on BEST lines elsewhere on the body, the author investigated BEST lines on the lower limb. Using a specially designed tensiometer, inherent skin tension (pretension) and wound-closing tension were studied along with the force needed to bring the wound edges together after excision of a lesion in 23 cases with defects ranging from 1.5 to 4.5 cm in diameter.

Relaxed Skin Tension Lines (RSTL) After Cox and Bulacio replicated Langer's study, albeit with slightly different results, Rubin attempted to understand the relaxed tension lines of the face. Rubin presented a paper on skin tension lines, describing his method of making an imprint of facial skin lines using a chemical-coated paper.
