_Fibrous tissue_ is a dense fibrous connective tissue coming from the mesenchyme and consisting of collagen and elastic fibers, supplemented by various cellular elements. As we age, collagen fibers lose their cross-striations, becoming less rigid, the elasticity of the tissue is impaired, which is easily torn, but begins to smoothly deform, forming wrinkles and folds - a process called aging of skin elasticity.
To a greater extent, the tissue is responsible for the firmness and elasticity of the skin: if the integrity of the fibrous tissue is compromised, then it loses its rigidity and can be felt as a bump-like protrusion. The appearance of fibrosis indicates the replacement of young cells in the thickness of the skin with connective tissue cells, including collagen. One of the main incentives
