👉 Tractema is a condition in which the skin becomes thickened, often due to a lack of collagen or elastin fibers, leading to a visible change in appearance and texture. This can occur in various parts of the body, including the face, neck, hands, knees, and ankles, as well as on the back, thighs, and feet. Tractema may be caused by several factors such as aging, trauma, excessive sun exposure, or certain medications like corticosteroids.
