Me and my skin

With an area of around 1.8 m², the skin is not only the largest but also the heaviest organ in the human body. It has a so-called acid mantle with an acidic pH value of 5.7.

Its functions are many. It protects us from heat, light, injuries and infections. The body temperature is regulated by sweating. It also stores water and fat and forms precursors of vitamin D under the influence of UV light.

It consists of 3 layers.

  • the epidermis (top layer)
  • the dermis (layer in between)
  • the subcutaneous layer (subcutis)

Epidermis and dermis (colored elastin and collagen)

The epidermis consists of layered cells. In addition to horny cells (keratinocytes), immune cells and others, it also contains pigment-forming cells, the so-called melanocytes. Their pigment melanin is distributed to the cells of the epidermis and thus determines the skin colour and its tanning. The epidermis represents the most outside part of our skin that shields us from our environment.

Collagen fibres (electron microscopic image)

The dermis consists of so-called fibroblasts, collagen and elastic fibres. They form the supporting structure of our skin. It also contains hair roots, blood and lymph vessels, sebaceous and sweat glands and numerous nerve endings for the perception of touch, temperature and pain. The dermis is particularly affected by the ageing process.

The subcutis consists of loose connective and fatty tissue. It protects us from the cold, stores energy and acts as a layer between the actual skin and the sheaths of our muscles.

The four cosmetic skin types


Normal skin shows a good balance between moisture and oil production. Pores are barely visible. The skin feels balanced and healthy overall.


Dry skin tends to retain less moisture and can therefore often feel flaky, rough and tight. It can also tend to be more sensitive and irritate more easily.


Oily skin produces excess oil, which can cause it to become shiny and clog pores. People with oily skin are prone to acne and blemishes.

Combination skin

Combination skin is a combination of different skin types. Typically, the T-zone (forehead, nose, chin) is oily, while the cheeks tend to be normal or dry.

Hormonal factors, environment and age cause skin types to vary.

Young and ageing skin in comparison


Skin ageing in itself is a completely natural process and begins at the age of around 25, even if no visible signs are recognisable at this time.

Time, genetic (endogenous) and external (exogenous) factors all play a role.

By these we mean

  • UVA radiation from the sun
  • Lack of or insufficient care
  • Inadequate sleep
  • Unhealthy diet
  • Air pollution
  • Smoking

Our skin lives and changes constantly. With increasing age, the supporting structure of our skin regenerates to a lesser extent. Collagen and elastic fibres become fragile and unstable.

The fat pad belonging to the skin also decreases. It becomes thinner, more vulnerable and increasingly loses its ability to retain moisture. Blood circulation decreases, which means that it is less able to be supplied with nutrients and oxygen.

To sum it up:

  • Wrinkles and lines on the face, around the eyes and the lips appear
  • Discoloration and pigmentation disorders might show up
  • the skin tends to frequent irritation or allergic reactions
  • the skin becomes rough
  • the skin becomes dry
  • the skin feels tight

The ageing process can not be  avoided completely.

Nevertheless, there are things you can do to delay it in order to maintain a youthful, radiant and healthy looking skin.
