Use cosmetics of hyaluronic acid and where it is found
Hyaluronic acid is an excellent moisturizer because it prevents the evaporation of water, forming a non-occlusive film that helps to counteract skin dehydration. Furthermore, hyaluronic acid has anti-aging properties and is a good ally in the prevention of wrinkles and signs of aging .
Hyaluronic acid is used in face, body and eye and lip contour products for the care of mature and dehydrated skin; it is well tolerated even by sensitive skin and has no side effects.
Hyaluronic acid is commercially available in the form of sodium hyaluronate (or sodium hyaluronate), a water-soluble salt to be inserted in small percentages (01-05%) in the aqueous phase of lotions, creams and gels ; often sodium hyaluronate in aqueous solution is available, to be added to cosmetic formulations at higher dosages (from 1 to 3%).
The hyaluronic acid solution can also be prepared at home, dissolving 1 gram of sodium hyaluronate in 99 grams of preserved distilled water (ie distilled water in which the preservative has been dispersed, properly dosed): after mixing, the solution is left to rest for a few minutes until a gel is formed.
The hyaluronic acid used in cosmetics can be of vegetable or animal derivation : in the first case, sodium hyaluronate is obtained by fermentation of wheat thanks to yeasts and bacteria, while hyaluronic acid of animal origin is extracted from rooster crests .
