— Wie ist unsere Haut
Our skin consists of three layers: Upper skin (epidermis), dermis and lower skin (subcutis). Each layer performs important functions. For example, the epidermis is responsible for protecting us from environmental influences such as UV light and dirt. The dermis consists of nerves, blood vessels, sweat glands, sebaceous glands and hair follicles. Its function is to supply our skin with nutrients. The subcutis or hypodermis consists mainly of connective tissue, which is filled with fat cells. The subcutis stores water, nutrients, fats and salts. It regulates the water balance and serves as a heat and nutrient reservoir. Thus, it protects us from hypothermia in winter.
The sebaceous glands are also clearly visible in our picture. Even if they have often annoyed us with the one or other pimple, they are very important for our skin, because they protect it from drying out and keep germs away from us.
What are the tasks of our skin?
Our skin has many different tasks. It acts as a protective shield for our body, protecting us from water loss, dirt, UV rays, pathogens, fungi, bacteria, chemicals, pressure and friction. It also stores the good nutrients and heat in our body. Through sebum and sweat, it regulates heat and moisture.
Our skin is also responsible for tactile perception. It can distinguish between different substances and recognize touch. Through ultraviolet-induced synthesis, our body is also supplied with vitamin D through our skin. So our skin does a lot! All the more important that we also take good care of it.
The appearance of our skin is co-determined by many different factors. Age, genetics and hormones, for example, are factors that we can hardly influence. The situation is different when it comes to our diet, sufficient sleep, avoiding nicotine and unprotected UV radiation, and the correct application of our skin care.
