The skin’s functions
Our largest sensory organ
The skin protects the body from cold, heat, UV radiation and pressure and prevents the penetration of micro-organisms and the loss of water and heat. We perceive sensations such as tenderness, pain, pressure and temperature through the skin. "A life dedicated to skin" is the motto that has accompanied Louis Widmer since it was founded over 50 years ago.
Beautiful, fresh skin requires
Beautiful, smooth skin radiates youthfulness and freshness. But as the skin matures, it becomes more demanding. Louis Widmer offers a complete care programme, tailored to the needs of every skin type. Two factors are crucial in determining the correct individual skin care programme – skin type and skin condition.
From about the age of 30, skin starts to show the first signs of ageing. This is when production of oil in the skin decreases, leading to a loss of moisture – and the first wrinkles appear. The quality, production and amount of collagen fibres and elastic fibres in the skin also decrease. Skin becomes thinner and less elastic, which results in wrinkles. Although this process cannot be stopped, with proper care it can be slowed down effectively. "Proper" care means regular care that is tailored to your skin type and its specific needs.
As our largest sensory and contact organ, the skin has a surface of one and a half to two square metres and, depending on body size, weighs two to four kilogrammes, excluding its lower layer or subcutis. Acting as a shield, it prevents toxic substances, dirt, radiation and microorganisms from entering the body. It also regulates our body temperature and moisture balance and performs important metabolic functions.
- The epidermis protects us against external influences.
- The dermis (corium) is responsible for skin nutrition, immune defence and our sense of touch.
- The hypodermis (subcutis) stores fat and water in the fat cells and is responsible for the skin's elasticity.
As the top layer of the skin, the epidermis performs a range of protective functions. The underlying dermis softens knocks or blows and feeds the epidermis through means of the blood vessels. The nerves that detect cold and heat and that are responsible for our sense of touch are also located here. The fatty tissue in the hypodermis protects the body against cold and defines the body’s contours.
Between the dermis and the hypodermis, there are 100-300 sweat glands per square centimetre, which regulate our body temperature. The more than two million sweat glands are also important for metabolism. Not only do they secrete the products of metabolic degradation, such as potassium, calcium, magnesium, chloride, phosphate and sulphate, but also urea and fatty acids, which ultimately lighten the burden on the kidneys.
