Hyaluronic acid: beauty care

Hyaluronic acid is a substance Of course produced by the human body, and is one of the most important components of connective fabrics. It is precisely this molecule that gives the skin its particular properties of resistence And maintenance of the form. Has the purpose of moisturize And protect fabrics.

In our body it is:

• in the vitreous humor of the eye
• in the synovial liquid of the joints
• in the skin
• in the cartilage
• in the tendons
• in the umbilical cord
• in the walls of the aorta

Its concentration within the connective tissue, unfortunately tends to decrease with advancing age. This constant decrease is among the main responsible for skin aging.

Structure and functions

From a structural and chemical point of view, hyaluronic acid is a molecule formed by the repetition of long sequences of two simple sugars: glycuronic acid and n-acetylglucosamine, which form an extremely polar molecule to highly soluble in watery environments, a fundamental feature For Keep the fabrics hydrated. At the same time, he has a high affinity with other molecules and components of the extracellular matrix, which allow him to form one reticular structure With 2 very important functions:

1. acts as a real scaffolding molecular, which allows tissues to maintain tone and shape;
2. acts from filter Against viruses and bacteria, in fact only the substances with very low molecular weight manage to spread freely in the tissues, the others remain "trapped" in the dense stitches of this network.

Considering its important properties, hyaluronic acid is used both in the medical and aesthetic fields. In medical scope It is used, for example, in the treatment of arthrosis with infiltrations of hyaluronic acid in the articulation, as an eye lubricant or to stimulate the regeneration of the tissues. In aesthetic field, On the other hand, it is used as a filler to volume the lips, stretch wrinkles, remodel breast and body and correct other types of imperfections. In this case the substance is injected directly to the point to be treated. The costs are quite high, especially considering that the aesthetic result is not permanent due to the progressive reabsorption of the substance, which makes the periodic repetition of the intervention necessary.

Hyaluronic acid can be classified according to the uses (doctor or aesthetic) and according to his molecular weight. There are three types of hyaluronic acid which, in some cases, such as in cosmetic creams, are used simultaneously to obtain more effective results. 

Types

• High molecular weight: It acts on the more superficial layer of the skin since its structure does not allow it to penetrate deeply. It is able to retain larger quantities of water and, remaining on the surface, also creates a barrier for outgoing water, making the skin can maintain higher and longer hydration levels. It is very suitable for Young skin who only need superficial hydration and wrinkles prevention. It is also indicated for those looking for hydration without weighing their face with products that translate out of high temperatures, such as the fat and/or impure skin.
• Medium molecular weight: Even this type cannot penetrate the deepest layers of the skin. He is responsible for the retention of water in the medium/superficial layers of the epidermis.
• Low molecular weight: He manages to penetrate up to the deepest layers reaching the hypoderma, where he stimulates the production of collagen, the main protein of the connective tissue, which guarantees tone and elasticity skin. It is very suitable for mature skin, which need deeper hydration and to counteract wrinkles and already existing time signs. 

Hyaluronic acid in the cosmetic field

As already anticipated, the natural production of hyaluronic acid by our body constantly decreases over the years, therefore no longer succeeded in contrasting the rhythm of degradation that always remains the same. This deficiency of hyaluronic acid in connective tissues is the main responsible for theskin aging and the formation of wrinkles and sorting of the skin. That's why many products for skincare and cosmetic, nowadays, contain hyaluronic acid inside in concentrations ranging from 0.1% to 2%. To be more precise, hyaluronic acid is not used in cosmetics (scarcely soluble in hydrophobic tissues), but the sodium hyaluronate, or its saline shape, which looks like a soluble white powder in water.

Suisselab Skincare line

 

Both in the face cream Regenera Hydra Visage than in the eye area Lifting Eye Contour it is content Hyaluronic acid with multiple weight, in order to guarantee both surface hydration, and a deeper action that can go to fill wrinkles from the inside and stimulate the production of collagen. Not to be underestimated, also the filmgenic action of hyaluronic acid with high molecular weight that creates a protective barrier on our skin, protecting it from bacteria and pollution. 

In the first place in the formulation of both products, moreover, we find the snail slime, of course rich in collagen and elastin (to deepen Read here). The presence of vitamin e (tocopherol), an antioxidant that protects the skin from the damage of free radicals.
