Saving moisture is one of the most important functions of the skin, and on how successfully the skin with it copes, in many ways depends on its appearance. Preservation of moisture was a matter of life and death for the first land animals. According to the laws of equilibrium, water tends to be evenly distributed between the internal environment of the organism (where the moisture content is of the order of 70-80%) and the environment. Therefore, to leave on land and settle in the areas remote from reservoirs, not being afraid of drying, it was possible only to those whose skin proved to be a sufficiently reliable barrier to water. At the same time, the skin was given a double load - it had to retain moisture inside the body and take care of its own moisture.
From loss of moisture, the body is partially protected by the fatty layer (hypodermis), which envelops our bodies like a mantle. Behind the hypoderma begins the dermis, which has its own source of water supply - a network of blood vessels. Leaking through the walls of the capillaries into the intercellular space, the water immediately binds to the molecules of the intercellular substance of the dermis, forming a gel. Thus, the derma also saves water, but it acts not as a barrier, but rather as a sponge or diaper.
Surplus water slowly rise to the surface of the skin, seeping into the epidermis. In the epidermis there are already no blood vessels, so its hydration is completely determined by how much water enters it from the dermis, and by how intensively it evaporates from the surface of the skin.
So, in the skin there is a dynamic balance between the evaporation of water and its intake from the blood vessels. Normal water balance is very important for the appearance of the skin. When hyperhydration, the skin swells and shrivels (like with prolonged bathing), and when dehydrated, it loses its elasticity and becomes wrinkled.
Most often the skin suffers from dehydration, so many cosmetics aim to moisturize the skin. Change the rate of water intake from the vessels of the dermis is very difficult. To some extent, this is facilitated by massage, contrast baths and masks that stimulate blood flow in the skin. It is equally difficult to increase the water-holding capacity of the dermis, for example, to increase the content of hygroscopic molecules, such as glycosaminoglycans and collagen. Therefore, the main impact point for cosmetics has always been the stratum corneum.
Moisturizers act as a kind of barrier preventing evaporation of moisture and, as a result, drying out the skin. Moisturizers extend the youthfulness of the skin, while maintaining its elasticity and softness. Regular use of a moisturizer helps prevent dry skin, especially in cold and windy weather.
Try not to use flavored moisturizers containing a large number of ingredients. The usual petroleum jelly is a quality inexpensive moisturizer, which is always at hand.
Moisturizers also protect the skin from cracking. There are different types of moisturizers according to skin types, so when buying a cream, make sure it is suitable for your skin type. Humidification is extremely important for the health and beauty of the skin. If you are unhappy with complexion, pay attention to tonal moisturizers. Moisturizers prevent skin aging and wrinkles only if they contain sunscreen ingredients. Vegetable-based moisturizers are easy to use, quickly absorbed and do not cause skin irritation.
How to apply moisturizer?
Before applying a moisturizer, wash your hands, wash with a cleanser and warm water.
After cleansing and toning the skin, lightly moisten it with water. Wipe the moisture with a tissue almost dry, then apply a small amount of moisturizer to the face and apply a uniform spread over the face without rubbing it into the skin. Regardless of skin type, the moisturizer is best applied to slightly damp skin - it helps to retain moisture in the upper layers of the skin, as if "sealing" it. So the moisturizing effect persists for a longer time.
Owners of oily skin enough to use a moisturizer once a day; But other types of skin (in particular, dry) require more frequent moisturizing. Men can not use the tonic, but they should not neglect the moistening of the sensitive skin around the eyes. If the skin around the eyes is particularly prone to dryness, it is recommended to pick up a separate moisturizer for it. If the skin of the face is uniform, for the area around the eyes you can use the same cream as for the whole face.
Moisturizers for face
Typically, moisturizers for the face are intended for use in the morning. All the currently available moisturizers are formulated in such a way that they do not close the pores, do not cause acne or an allergic reaction. The composition of moisturizers for dry skin includes mineral oil, petroleum jelly, glycerin and cyclomethicones - all these ingredients prevent dehydration and dry skin. Moisturizers for normal skin usually contain less fatty ingredients, for example dimethicone, cyclomethicone and light oils (cetyl alcohol). Moisturizers for oily skin are very light, Dimethicone is used as the main active ingredient.
