Hyaluronic acid
INCI name
Sodium Hyaluronate
Origin
vegetable
What is this?
Scientifically, it is a large carbohydrate molecule, capable of retaining water. It is found in many human tissues: in the skin, cornea, cartilage, etc.
Its manufacture
In natural and organic cosmetic, it generally comes from a wheat fermentation process (non-GMO) under the action of yeasts. It comes in the form of a white powder that is mixed with aqueous elements in a cream, milk or serum formulation.
His action
Hyaluronic acid is characterized by its high water retention capacity: its molecules can retain up to 1000 times their weight in water. It is therefore important for keeping skin supple and well hydrated.
In cosmetics, it is a widely used ingredient. It is described as being able to plump the skin and deeply hydrate it.
This active ingredient is useful for combating skin aging, wrinkles and dehydration. It makes the formula capable of “capturing” moisture at the skin level (epidermis).
Different molecular weights
The penetration of hyaluronic acid into the skin depends on the size of its molecules, called molecular weight.
Large molecules (high molecular weight) act on the surface: they moisten the skin and protect it from external aggressions.
Small molecules (low molecular weight) can penetrate the layers of the skin and thus soften it, hydrate it more lastingly and plump it up.
