Hyaluronic acid in cosmetics, especially those anti-aging, is a common occurrence these days. The substance is added to creams to give the skin a velvety smoothness, firmness and elasticity.
Hyaluronic acid is a substance naturally present in the human skin. Until the age of 25, our body produces it in significant quantities, but then the synthesis of this compound significantly decreases. This happens under the influence of unfavorable environmental factors, excess ultraviolet light, frequent diseases, improper diet or addictions. As a result, the skin becomes flabby and dry, marked with deep wrinkles.
With regular use, hyaluronic acid contained in cosmetics forms an ultra-thin film on the skin, which maintains the right level of hydration, while not interfering with metabolic processes. Hyaluronic acid is biocompatible with the skin, so it does not cause allergies or irritation (except in rare cases when the cosmetic agent was improperly selected)
In addition to its primary task, which is to maintain an adequate level of hydration, hyaluronic acid saturates the skin with active substances that help it stay healthy and beautiful. The substance also accelerates cell regeneration and prevents the destruction of collagen and elastin fibers.
When the skin becomes dry and flabby, and here and there wrinkles and furrows appear, we begin to look for the causes of the changes that have occurred, especially if they are not related to age. In this case, the reason may be a deficit of hyaluronic acid: it is simply essential for the skin of the face and body. For this reason, it is included in most anti-aging cosmetics.
Hyaluronic acid plays an important role in the process of ion exchange, as well as the immune mechanisms of the skin. In addition, by applying it to the skin, the regenerative processes in the cells are stimulated.
The use of hyaluronic acid allows you to:
– regain a natural level of hydration;
– significantly smooth out shallow wrinkles;
– create a thin film on the skin, which protects against ultraviolet radiation and other adverse environmental factors.
Hyaluronic acid is included in the composition of cosmetics from the higher and medium price brackets. It can be found in moisturizing and anti-aging creams, lotions, lotions and balms, sunscreens, gels for the skin around the eyes, lip fillers, neck and cleavage preparations
In modern cosmetology hyaluronic acid is used in mesotherapy, biorevitalization treatments, as well as lip and face modeling.
The effect of creams with hyaluronic acid is determined by several factors. The active substance (sodium hyaluronate) acts as a link between collagen cells in tissues. In addition, hyaluronic acid in creams guarantees intense hydration, which accelerates all processes inside the cells. This explains the rejuvenating effect in the case of mature skin and the prevention of premature aging in the case of young skin.
Hyaluronic acid in creams can be found in two varieties: low-molecular and high-molecular.
Creams with a low-molecular variety of acid are obtained according to the latest technology, so quite recently appeared on the cosmetic market. Due to the fact that they instantly penetrate into the deep layers of the skin, they have a beneficial effect on the appearance of the complexion.
Preparations with a macromolecular variety of acid are more affordable. Their task is to maintain the appropriate level of hydration in the horny layer of the skin. This type of cream may be used by younger people, who are over 25 years old, as a prevention of premature skin aging. Such a preparation is absorbed into the epidermis, making the skin soft, tight and moisturized.
When facing the choice of a preparation, it is necessary to pay attention to the concentration of the active substance. Cream for everyday face care should not contain more than 1% of sodium hyaluronate. Professional preparations are distinguished by a richer composition. The concentration of the acid included in their composition can reach up to 5%.
