How do you identify a Langer line?
The best-known skin tension lines are the Langer lines, named for Karl Langer, who described them in 1861. These are also called cleavage lines because they were determined by piercing cadaver skin with an awl (a small pointed tool for piercing holes in leather) and observing the orientation of the resulting wound [1].
What causes Langer lines?
Langer lines were created by static forces in the skin of cadavers [Figure 29A]. The normal wrinkle lines are produced by dynamic forces acting on the skin of a living person. Figure 29. Langer’s “cleavage lines” were never meant as guidelines for optimal directions for surgical incisions or excisions.
Where are Langer lines located?
Abstract. 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 correspond to the natural orientation of collagen fibers in the dermis, and are generally parallel to the orientation of the underlying muscle fibers.
What is skin tension line?
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.
What are blaschko lines?
Blaschko lines are consistently V-shaped on the upper spine, S-shaped on the abdomen, inverted U-shaped from the breast area to the upper arm, and perpendicular down the front and back of the lower extremities. They never cross the anterior truncal midline but run along it.
How do I get rid of cleavage lines?
Deep-moisturizing or plumping masks help to improve the hydration levels of skin on the chest and can work to smoothen and mask fine lines while preventing further wrinkles. Retinoid creams can also help to boost natural collagen levels, fending off fine lines and wrinkles.
What causes flexure lines?
Flexure lines, found in the fingers and toes, etc. are places where the dermis has folds to accommodate joint movement. Skin coloration comes from three sources: Melanin from melanocytes, taken up by keratinocytes.
What are the lines in the skin called?
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 perpendicular to the underlying muscle fibers.
Do blaschko lines glow?
Blaschko’s lines or the lines of Blaschko are a series of stripes found on human and other animal skin. The lines follow the path of embryonic skin cell migration. Normally, the lines are not visible under ordinary light. However, they may be viewed under black or ultraviolet light.
Does everyone have blaschko lines?
Most people will never see their own stripes. As Dr. Blaschko noted, there are dozens of skin conditions that follow these lines, but most of them affect patches of skin or a single body part, not the entire body.
How do I stop chest lines?
Adopting a skin care routine that includes cleansing, moisturizing, exfoliating, and applying topical treatments to your décolletage can boost the appearance of this area. Regularly wearing sunscreen and protecting your skin from the sun can also go a long way to help slow down the signs of aging and skin damage.
What are Langer’s lines on the human body?
Langer’s lines are lines of tension or cleavage within the skin that are characteristic for each part of the body.
Is the Langerhans cell a white blood cell?
The Langerhans cell is a class of white blood cell. The symptoms and seriousness of Langerhans cell diseases are determined by where the proliferation of the Langerhans cell occurs. If the cells multiply and remain mostly in the skin, the result often is localized to the skin.
What are Langer lines of skin tension called?
Anatomical terminology. Langer’s lines, Langer lines of skin tension, or sometimes called cleavage lines, are topological lines drawn on a map of the human body.
