Hyaluronic acid is a chemical compound naturally occurring in the human body - mainly in the skin (especially in the stratum spinosum), but also in the synovium, walls of blood vessels and vitreous body of the eye. It is one of the components of the intercellular matrix. Its presence in the skin owes its smoothness, firmness, and elasticity. Naturally, it has the form of sodium salt - sodium hyaluronate.
With age, the amount of hyaluronic acid in the human body decreases. The result is significantly less skin elasticity, wrinkles, and difficulty in staying hydrated. Hyaluronic acid completely disappears from our body around the age of 80. Of course, this can happen faster through factors such as smoking, hormone disruption, or air pollution.
Properties of Hyaluronic Acid
The most important feature of hyaluronic acid is its hygroscopic properties (it binds molecules - absorbs water). One hyaluronic acid molecule can bind about 250 water molecules. This has made hyaluronic acid a popular ingredient in moisturizing, protective and anti-aging creams.
Form of hyaluronic acid
Cosmetics
In cosmetics we meet hyaluronic acid in different structural forms:
- short-molecular - moisturizes long-term because it penetrates the deeper layers of the skin.
- medium-molecular - has a strong moisturizing effect (only in the horny layer). Has an immediate but short-lasting effect. Gives the appearance of smoothness and firmness, which, unfortunately, disappears quickly.
- High-molecular - protects the skin against water evaporation due to the thin layer it forms on the skin.
In some cosmetic products you can meet with hyaluronic acid closed in liposomes to facilitate penetration into the deeper layers of the epidermis.
Aesthetic medicine
In aesthetic medicine hyaluronic acid is used to fill wrinkles and to enlarge and model lips. It occurs in different forms of cross-linking:
- in mesotherapy cocktails it has a non-crosslinked form
- Cross-linked hyaluronic acid becomes a filler
Hyaluronic acid filler is in the form of a powder obtained by biofermentation, purification and drying. The surgeon performing the procedure adds water, resulting in a filler in the form of a clear gel ready for application.
In addition to lip contouring, this filler is also used to restore tissue defects or smooth out nasolabial furrows.
History
The first use of hyaluronic acid was in the 1940s. It was used by veterinarians for racehorse injuries. Since the 1960s, it has also been used in ophthalmology - in surgery for retinal detachment and, later, in lens implantation.

The use of hyaluronic acid creams is necessary to maintain healthy, beautiful skin.
NMF xpress cream - a deeply moisturizing cream for use at any time of day or year. It uses liposomes to transport glacial water deep into the skin, prolonging the effect and moisturizing.
Novo - a night cream with 8% glycolic acid. Exfoliates dead skin cells, leaving the skin visibly refreshed and smooth.
City eye - an eye cream is a perfect supplement of the care. The skin in this area is delicate and requires a different, better adapted type of care, which will help to "cope" with bruising, "bags under the eyes" and wrinkles.
