HYALURONIC ACID: THE BENEFITS FOR THE SKIN

WHAT HYALURONIC ACID IS ?

This is one of the most discussed issues in the cosmetic field but few know what hyaluronic acid is and what it actually does. What hyaluronic acid is? Hyaluronic acid is a molecule produced naturally by our body and synthesized by fibroblasts. Present in a high concentration in the cutaneous layer, this polymer is responsible for the firmness and volume of the skin and it has multiple properties. Hyaluronic acid is able to absorb water in quantities of up to a thousand times its weight, so it acts as a cushion able to bind a large number of water molecules enabling the skin to be more hydrated, elastic and firm.

WHAT IS HYALURONIC ACID USED FOR?

Our skin naturally contains hyaluronic acid: the younger the skin, the higher the quantity of hyaluronic acid that keeps it hydrated. With the passage of time the acid hyaluronic are reduced, thus decreasing the capacity of the skin to remain hydrated and firm. This leads to the formation of wrinkles and so it is important to supplement the hyaluronic acid through the use of Skin Care products which contain it, so that the skin appears more elastic, hydrated and firm. Hyaluronic acid is therefore an excellent remedy against wrinkles.

Hyaluronic acid is known for its hydrating properties and for its ability to intervene in skin ageing. Hyaluronic acid is mainly used in products for the face, for the body, in supplements to drink,   especially for the care of mature, dehydrated skin. Hyaluronic acid does not produce collateral effects, a great added value even for sensitive skin. From 25 years it is recommended to use a cream or serum containing hyaluronic acid to prevent skin ageing and to maintain a healthy and radiant skin.

HOW MANY TYPES OF HYALURONIC ACID ARE THERE?

In cosmetic products, hyaluronic acid is very often found accompanied by terms that indicate the different molecular weights. However, certain terminologies of the derivatives, grouped on the basis of high, low or medium molecular weight, can cause confusion and very often the consumer does not know which hyaluronic acid choose.

Hyaluronic acid is a molecule that can be distinguished by its specific molecular weight, which is merely an index of the magnitude of the molecule.

Molecular weight and the magnitude of the hyaluronic acid molecule are linked by a directly proportional ratio: the larger the molecule, the greater the molecular weight will be, and vice versa, the smaller it is, the lower its molecular weight will be.

SO WHY DO WE NEED TO KNOW THE MOLECULAR WEIGHT OF HYALURONIC ACID?

The reason is very simple: the smaller the hyaluronic acid molecule is, the more easily it will deeply penetrate the skin and plump out the reticulum.

Hyaluronic acid with high molecular weight: this is able to form an invisible film on the cutaneous surface that can block the evaporation of water and combat skin dehydration.

Hyaluronic acid with medium molecular weight: this penetrates the skin and provides the water required to preserve the turgidity and firmness of the skin.

Hyaluronic acid with low molecular weight: this is able to reach the subcutaneous layers, acting on the production of collagen, the protein responsible for the density and firmness of the tissues. The effect is a temporary filling and smoothing of small wrinkles.

To obtain a filling effect, cosmetics must be used that contain molecules of hyaluronic acid with a low molecular weight. Otherwise, there is the risk that the molecules will remain on the surface without penetrating deeply enough to help the skin where it most needs it. This does not mean, however, that products based on hyaluronic acid with high molecular weight are of no use but only that the hydration due to hyaluronic acid will only concern the surface of the epidermis, where it can limit the evaporation of water. 

HYALURONIC ACID WITH HIGH MOLECULAR WEIGHT OR HYALURONIC ACID WITH LOW MOLECULAR WEIGHT: WHICH IS IT BEST TO CHOOSE?

A more mature skin requires products based on hyaluronic acid with low molecular weight since it needs to increase the quantity of this molecule in the subcutaneous layer, given that, with the passing of time, the levels of hyaluronic acid in the skin diminish.

A younger skin, on the other hand, may benefit from the superficial cutaneous hydration given by hyaluronic acid with high molecular weight. An invisible film is created that limits the evaporation of the surface water and preserves the elasticity of the skin.

The formulations in which hyaluronic acid is present with different molecular weights, on the other hand, will make the cosmetic more effective.

This is the case of the serum with hyaluronic acid in the 01CR line. A serum based on pure hyaluronic acid made up of a synergy of four hyaluronic acids with different molecular weights, it ensures the optimal hydration of the skin and an immediate filling effect. It hydrates the skin by counteracting free radicals, oxidative stress and skin ageing. The result of pure hyaluronic acid is immediately visible since the skin appears brighter, smoother and filled out since the first applicatio
