learned from a beautician how to save dry skin in heat and cold

We know how important pH is almost from childhood – thanks to advertising. But are there many who know what dry skin has and why this type of dermis is often sensitive? We forwarded the most pressing questions to a specialist.

NSloho holds and easily gives up water

If you open a textbook on dermatology, it will say something like the following: “Dry skin is skin with a reduced level of hydration in the stratum corneum and with an increased index of transepidermal water loss.” In simple terms, it does not hold water well and gives it away easily.

In this case, the degree of hydration of the stratum corneum is determined by the balance of bound (primary) and weakly bound (secondary) water. It depends not only on internal processes, but also on external factors. For example, at low air humidity, there is practically no secondary water in the stratum corneum – moisture content is 100% supported by a natural moisturizing factor. And he, in turn, depends on the physiological mechanisms of the body, which determine the process of binding water coming from outside (air, cosmetics).

With dry skin, complexes of hygroscopic molecules in the stratum corneum are not enough. The main signs of this: tightness, dullness, invisible pores, active peeling.

dry skin pH – alkaline

The pH of dry skin is shifted to the alkaline side. And this fact must be taken into account when leaving.

The main danger of pH disturbance is an imbalance in lipid synthesis and, as a result, barrier function. That is, pathogenic microflora begins to predominate on the surface of the skin.

I would like to draw your attention to the fact that the concepts of “dehydrated” and “dry” skin are different. In the first case, we are talking about a lack of moisture in the dermis, in the second – in the epidermis of the upper layer (here it is enough to change the care to get rid of the problem).

Often sensitive

Dry skin does not produce enough sebum. And because of this, it often begins to peel off. In addition, dryness of the stratum corneum is the cause of impaired barrier function. It is reduced, so the skin is very sensitive to external irritants. She reacts to even minor changes in care and does not forgive experimentation.

Keep this in mind if you want to try a new mask or foam.

Care should be selected by a beautician

Dry skin needs special care. It is ideal when a cosmetologist selects it, taking into account all the nuances and individual characteristics. But the main principle is one – to moisturize! Girls with this type of skin cannot ignore masks (at least twice a week), creams and serums. I highly recommend paying attention to pharmaceutical products with urea (more about it read here). For example, anti-irritation revitalizing cream Uriage or Lipikar balm from La Roche-Posay.

You need to protect especially carefully

Too hot or cold climates make the skin even drier, facilitating the rapid evaporation of moisture from the upper layers. And depending on what climatic conditions you are in, care is selected. For example, in the summer it is important to protect the skin from the sun, observe the drinking regime and introduce serums with a high content of moisturizing components into the beauty diet. During the heating season, it is imperative to purchase a humidifier. It will help you avoid many problems.
