In the modern cosmetology Hyaluronic Acid is a highly demanded substance, which is used for supporting youth, health and beauty of face skin. Being one of the most powerful skin moisturizers, Hyaluronic Acid is included into the vast majority of rejuvenating cosmetic products and procedures.
How does Hyaluronic Acid work?
Skin contains up to 15% of all liquid in body. The substance responsible for the liquid balance and its restoring is Hyaluronic Acid, which molecule is a one of structural components of dermal tissue. Besides moisturizing, Hyaluronic Acid connects and supports collagen and elastin fibers, that provide skin tone and healthy appearance.
Over time fibroblasts, that synthesize Hyaluronic Acid, reduce their activity and the quantity of HA in skin is getting lower. The scientists discovered that middle-aged people lose about 3% of this valuable component a year, so humidifying skin loses firm, elasticity, become flaccid. The face contour may become deformed, wrinkles and fine lines appear. It is important to note, that HA reducing is not related only aging, but harm of UV-radiation, lack of vitamins C and E, magnesium, zinc, iron.

The difference between Hyaluronic Acid and Sodium Hyaluronate
When choose moisturizing cosmetic, pay attention to its way of use. If we talk about Hyaluronic Acid, there are two kinds of this natural moisturizer: high-molecular and low-molecular. Hyaluronic Acid itself is related to the high-molecular substance, the low-molecular substance has the name Sodium Hyaluronate, which is a salt of HA with much less dimensions. This is a reason, why Sodium Hyaluronate is used in hyaluronic creams instead HA — it can get through the skin barrier, which is impossible for the pure Hyaluronic Acid.
