After having invited to take the test to find out what type of skin you have today we will see what are the characteristics of various types of skin.
The normal skin
It is a type of skin rather rare, found only in childhood and early youth, the skin has not yet been attacked by external factors or internal impact of all biological functions are normal, the color is uniform, the skin This looks cool, pleasant to the touch, almost turgid, there are no wrinkles surface is smooth and bright. The pores are very small, almost invisible; on the nose and Regulation at times appear certain comedoni; hydration and the state of tension are fair skin, the cheeks are sprayed, slightly pinkish and dilated capillaries (couperose).
If during the menstrual cycle or connecting of ovulation appear foruncoli in the lower third of the face, this is a normal event hormone; impurities disappear soon and do not require any special care.And what guarantees the normal skin appear smooth, velvety and soda is determined by the balanced functioning of the sebaceous glands and sweat because the film lipid-protein surface and hydration are in harmonious balance.The film lipid-protein surface is an acid protective film that covers the skin completely. Secreted comes from the skin glands (sebum and sweat) and above the cellular debris from the stratum corneum desquamation. The film is continually renewed and consists of a water-soluble and a fat-soluble fraction. The first is made up of inorganic elements sodium, potassium, calcium and organic elements: acid (mainly lactic), urea, amino acids. The percentage of these elements varies depending on age of the subject and the district affected skin. The fat-soluble part is represented for 60% of the glycosides and fatty acids and the remainder from Squalene and waxes.The hydration ensures the elasticity and flexibility of the skin. The human skin has an average water content of 70% is higher in deeper layers and tends to decrease gradually toward the surface for the normal process of keratinization. This phenomenon is natural physiological dehydration: water lost to evaporation is replaced by an equal amount coming from inside. In the stratum corneum, water is retained by the presence among the different strip of substances for the most protein known as factors of natural hydration. The main components of these factors are piroglutammico acid, sodium lactate and many amino acids. These water-soluble substances are protected by a lipid material: so you create a system of waterproof membrane that allows water-soluble substances to capture the water by osmosis, and prevents substances melt or outside when the stratum corneum is immersed in water.
Stable changes in the composition of the films lipidicoproteico or hydration layer of influencing the different types of skin. Often underlying the phenomenon are genetic factors predisposing; other times instead acting medications, diet, stress, substances linked to the workplace or city where you live. The most frequent skin changes are dry skin and skin fat. The first condition is due both to a reduction in the percentage of water (dehydration) and a decrease in the amount of sebum produced (ajoke).
The fatty skin is due to an increase, and sometimes even to a qualitative change of sebum secreted by the sebaceous glands.
In conclusion, the normal skin is a type of skin quite difficult to meet also with aging, tends to reach out to dry and dehydration.
