Derma is a part of the skin that is connective tissue. It consists of three components: fibers, the main substance and cells. It is a support for the appendages of the skin, nerves and blood vessels. Here, collagen and elastin are synthesized, as well as hyaluronic acid production. It is from the state of the dermis that the youth and beauty of the skin depend. Over time, the metabolism in the tissues decreases, which leads to the formation of imperfections. Creams with hyaluronic acid come to the rescue , one of which is the Libre Derm cream. Consider the properties of the dermis and how Librederm copes with the tasks.
What is a dermis?
Derma is the middle and main layer of the skin, which contains important components for its health. It contains fibroblasts, sweat and sebaceous glands, hair follicles, elastin and collagen fibers, glycosaminoglycans, hyaluronic acid and other chemical compounds. In addition, the dermis is the site of passage of blood vessels and nerve endings.
Due to its structure, thermoregulation occurs by secretion of sweat glands and changes in blood flow. With the help of hyaluronic acid and collagen dermis, the protective function of the lower structures is performed. In addition, the middle layer of the skin provides sensitivity to the skin.
Dermis layers
The dermis consists of two layers: papillary and reticular, and its total thickness varies from 0.3 to 3 mm, depending on the site. The papillary layer is very thin. It is composed of an amorphous structureless substance and connective tissue fibers. In appearance, it resembles papillae that lie between the crests of spiky cells.
The mesh layer is thicker. It is located after the papillary layer to the subcutaneous fat. It is composed of collagen bundles of fibers that lie parallel to the surface of the skin. The mesh layer provides the strength of the skin, which varies depending on the lined area of the human body.
The internal composition of the dermis
Derma is a rather poor layer of skin cells. There are structural units of smooth muscles, as well as fibrocytes. Fibroblast is considered the main cell of the dermis, since elastin, collagen and proteoglycans are synthesized inside it.
One of the main components of the reticular layer of the dermis is collagen. It accounts for about 70–80%. This protein plays the role of both building material and a binder. Collagen consists of smaller particles - tropocollagen, each of which is represented by three spiral protein chains. They are connected to each other in parallel, stacked in a "head to tail" sequence, and have cross-linking. So collagen fibers are formed , which then pass into twisted bundles resembling twine. Their structure provides greater stability and resistance of the structure to stretching. Collagen fibers have plexuses in different directions, due to which a three-dimensional network is formed.
Elastin makes up 1-3% of the reticular dermis. This is a glycoprotein, the fibers of which repeat the course of collagen structures. They provide skin elasticity, therefore, their number is significantly increased in those areas where maximum stretching is necessary. These include the face area.
Weaving together, the fibers of elastin and collagen form an inextricable three-dimensional network that serves as a supporting frame to which all the structural elements of the dermis are attached. These include glycosaminoglycans, the most famous of which is hyaluronic acid.
The importance of hyaluronic acid in the dermis of the skin
Glycosaminoglycans are able to bind a large amount of water and sodium, potassium or calcium ions. Due to this property, the intercellular substance becomes jelly-like, and the tissues become full. Enveloping elastin and collagen fibers, they provide them with nutrition and protection. In addition, hyaluronic acid together with proteoglycans prevents the spread of pathogenic bacteria.
The lack of hyaluronic acid leads to a thinning of the protective membrane of collagen and elastin fibers. The amount of trapped water is reduced. The skin loses moisture due to which it becomes loose and flabby, the process of its withering starts. Reversing these changes is possible only by restoring the production of hyaluronic acid. Perhaps this is due to different procedures: special diets, dietary supplements, biorevitalization and mesotherapy, cosmetic creams.
Hyaluronic acid in creams: is it effective?
Creams with hyaluronic acid have become very popular. They are used in the lines of cosmetics of the age category 30+. Is their use effective, because the dermis is a layer of skin that you won’t get so easily? Creams with hyaluronic acid are really very effective. Moisturizing texture creates a kind of film that allows air to pass through. It helps to retain moisture in the epidermis, making the skin look fresh. A sufficient amount of water in the fabric smooths the surface and wrinkles. The result appears almost instantly.
