Anatomy and physiology of the skin
In order to treat and care for your skin properly, it's worth knowing how skin is made up. With dermo-active ingredients, we can give our skin the essential building blocks it needs.
The first zone of defence in the human body is the skin covering the entire surface of the body. Skin is Latin for derma, as is dermatologist. The interesting thing is that our skin does not only protect us, it also performs many functions, although its primary role is mechanical protection, including radiation protection. In addition, the skin is responsible for regulating body temperature (perspiration) and protecting against dehydration, but it is also the main store of nutrients and water. You would think that would be the end of its role, but medical science has shown that the layers of the skin have multiple functions. How many layers are there?
Three skin layers can be distinguished.
The layers of the skin: the top layer is the epidermis, the bottom layer is the dermis (corium) and the third layer is the deepest layer of skin (subcutis) that connects the two. We need to take care of all three if we want beautiful skin.
The nerves of the brain and spinal cord nerves are segmentally innervated by the skin (dermatomas), but the supply area of the adjacent nerves partially overlaps. The anatomy of the skin is superficially seen as an intertwined apparent unit.
In addition, there are also pigment-producing cells, the elongated melanocytes, the Langerhans cells involved in antigen presentation, which are part of the immune system, and Merkel cells.

The main derivatives of the skin:
- Hair
- Fur
- Nail glands
- Blood gland
- Sebaceous gland
- Gland
Even in the event of mechanical damage, the leather parts do not separate. So the structure of the skin, or the function of the skin, does not stop at just external protection, it is much more complex.
The stratum corneum on the surface of the skin is constantly renewed, a process of physiological regeneration or cell renewal.
Cloud - (epidermis), the layers of the epidermis: the upper layer of the skin is a multi-layered squamous epithelium, which is visible visually, with a layer of cylindrical epithelium, the subcutaneous connective tissue, a layer of stratum spinosum, and a layer of cells where horn formation begins. The epidermal layers are the most sensitive to external influences.
90% of the cells in the basal layer are constantly dividing to produce new cells, which are pushed further and further away from the nourishing dermis layer of blood vessels under the epithelium, leading to their slow death as they differentiate. In the process, they flatten and accumulate the protective horn precursor (keratohyalin), which, as they die, form a layer of horn and eventually wear off. The epithelium contains the pigment granules (melanin) that determine the colour of the skin and protect it from harmful radiation. They are produced by pigment cells (melanocytes), which make up 10% of the epithelium. Free nerve endings are located between the cell lines of the epithelium.
Beneath the uppermost stratum corneum of human skin, there is also a shiny layer (stratum lucidum) of granular cells where the keratohyalin liquefaction soaks into the cells.
What you need:
- Healthy renewal - organic exfoliators, peels
- Hydration - healing water, hyaluronic acid, collagen, etc.
- Sunscreens, antioxidants (DNA protectors, cell regenerators) - Totarol, Jericho rose, stable vitamin C, stable vitamin E
- Anti-inflammatories (protect cells from ageing) - Allantoin, Bisabolol
Irha - the middle layer of the skin, which makes up 4-6% of our body mass. What is found in the dermis?
The layers of the dermis, or dermis structure: underneath the epithelium is a network of elastic fibres called the fibres of the dermis, or cells of the dermis, which are made up of two layers - the stratum papillare, the stratum in the epithelium and papillae, e.g. fingerprints, skin surface patterns and - the stratum reticulare, the deeper reticular layer of the dermis made up of regularly running fibres.
It is made up of loose fibrous connective tissue, collagen and elastic fibres and connective tissue cells. It has two layers consisting of a fine fibrous, warty layer (stratum papillare) extending into the base of the epithelium like a glove finger, and a deeper, coarser fibrous reticular layer (stratum reticulare). The stratum papillare contains the blood vessels that feed the epithelium and most of the receptors that can sense heat, pain, pressure and touch. The specific arrangement of the papillary layer is also responsible for the individualised skin scales on the fingers, palms and soles.
Hair follicles are found in different areas of the outer coat. Hair follicles protrude from the skin, are made up of shed epithelial cells and are formed by the hair follicle/hair follicle surrounded by blood vessels. The sebaceous glands open near the surface of the hair follicles and protect and polish the hairs with their fatty secretions.
The role of dermis is mainly to ensure the elasticity and durability of the skin.
What you need:
- Collagen - Plant collagen, collagen production stimulating signal peptides
- Ceramides - ceramide complex, matrix building signal peptides
- Amino acids - peptides - silk protein
- Highly bioavailable skin lipids - valuable active oils (argan, pomegranate seed, raspberry seed, jojoba, etc.)
Boiling water - (tela subcutanea) is the deepest layer of the skin, made up of fatty connective tissue. Its development varies from one part of the body to another, and its distribution differs between men and women. Its function is to store energy, insulate, cushion against major physical impacts and help the skin to move as needed.
Healthy skin gives the face a full, beautiful shape. It is nourished by a good quality, healthy blood supply, so the main requirement is that the underlying musculature is strong, flexible and well supplied with blood. Skin regeneration is an important part of natural facial correction.
DRHAZI Bio Facial Plastic - Aim for a healthy and beautiful face!
The skin of the face has a specific structure, with the facial muscles (mimic muscles) radiating directly into the connective tissue of the skin, and lacks the layering described above. A specific feature of the facial muscles, or mimic muscles, which are located under the skin of the face, is that they partly originate in the bones of the facial skull and radiate into the skin of the face, and partly originate in the skin of the face itself and adhere to it. Self-recurring muscles form the muscular base of the lips that close the mouth and the muscular covering of the eyelids that close the eye slits. The facial muscles are innervated by the facial nerve VII (facial nerve; nervus facialis). Therefore, to regain the youthful radiance of our face, we must not only work on rejuvenating the facial skin, but also on releasing tension in the facial muscles.
