The skin is the largest organ in the human body. It makes up about one-sixth of the body’s weight. How it is structured, functions and what is good for it.
The following topics are covered in this article
The skin covers the entire body and merges into mucous membranes at openings such as the mouth or anus. It is loosely connected to the underlying tissue and varies in thickness, from 0.5 millimeters on the eyelids to 4 millimeters or more on the palms of the hands and soles of the feet.
The skin protects the body from harmful external influences such as extreme temperatures and dryness, and from pathogens such as viruses and bacteria. Special nerve receptors allow the perception of pain, heat, cold and pressure. Skin plays a role in temperature regulation, protects against ultraviolet rays and produces vitamin D. If exposed to sun, wind and air pollution for decades, the skin becomes flabby, dry and wrinkled.
This is how the skin is structured
The skin is composed of three layers.
The epidermis consists of five layers. Dead cells are always replaced by cells from the lower layers. This process takes about four weeks. Cell division takes place in the lowest layer of the epidermis. In addition, cells that form pigment and thus determine the color of the skin are located. When exposed to sunlight, more pigments are formed, the skin turns brown. Above the lowest layer lies a layer of horn cells, which ensures that the skin is watertight. Over it lies a glossy layer with several cell layers. This is particularly noticeable on the palms of the hands or the soles of the feet. On the very outside lies the horny layer. Most cells of this layer are already dead. After about two weeks they peel off completely.
The dermis is the inner layer of the skin. It contains a fibrous network of collagen and elastin as a supporting and displacing layer and is permeated by blood vessels, nerves and fat corpuscles. Specialized structures such as hair follicles, sweat and sebaceous glands are located in the epidermis and dermis.
The subcutaneous tissue (subcutis) is made up of fat, protects the body from extreme temperatures and serves as a fat depot. The thickness of this layer varies greatly from body region to body region and from person to person.
This is good for the skin
Martin Tschumi, a certified druggist HF, has compiled the most important tips for healthy skin for you:
For eczema, spagyric mixtures or homeopathic ointments are often helpful. Anti-allergic ointments or creams with silver complex also have a healing effect on problems with the skin.
To prevent premature skin aging, you should protect the skin from UV radiation with special products. In addition, a healthy lifestyle is important, because an unbalanced diet, stress or smoking can also cause premature aging of the skin.
In addition, it is important to match cleansing and care products ideally to the respective skin type. Get advice at your drugstore.

Without the heart, nothing works in the human body. It is our most important organ. If it no longer functions, we are dead.
The brain controls everything

Thyroid gland regulates metabolism
Like a large butterfly, the thyroid sits in front of the larynx. And it is equally sensitive. If too many or too few hormones are produced, diseases are preprogrammed.
