 Chemically,
hyaluronic acid is a polysaccharide of Glycosaminoglycans family, which is part
of animals' and human beings' skin. It is contained in joints fluid, in
ligaments, and in vitreous body, umbilical cord, shark's skin, and in some
bacteria cells. Hyaluronic acid synthesis in derma and epidermis starts slowing
down as early as 15 years of age and accelerates under the influence of
different factors.
In fact, hyaluronic acid can absorb more than 1,000 times
its weight in water allowing it to hydrate the skin and other areas that it
contacts. In addition to its hyper-hydration properties, hyaluronic acid is
also known for its role in wound healing and in the prevention of scarring, the
reason why it is highly valued in cosmetology and aesthetic surgery. Hyaluronic
acid helps our skin to maintain its elasticity, hydration and firmness levels
which is essential for young and radiant skin. Compared to
other moisturizers, hyaluronic acid has got a number of advantages. Hyaluronic
acid has the highest hygroscopic property (the ability to absorb moisture)
compared to other most common moisturising agents such as glycerine and
sorbitol. At the same time, unlike glycerine, it stays active in dry
atmosphere.
Hyaluronic
acid is justly called a molecular sponge sometimes. In cosmetics hyaluronic
acid (or its natrium salt, natrium hyalurate) is mainly used as a moisturising
component and is considered one of the most «pleasant» cosmetic components. At
present hyaluronic acid and its salts are used in moisturising creams,
lipsticks and lip balms, anti cellulite lotions, eyelid gels, sun tan lotions,
and anti-inflammatory lotions, wound healing and anti-sun repairing lotions. It
is compatible with skin, does not cause allergic reactions or irritations.
Cosmetics which contain hyaluronic acid soften, moisturise and protect the
skin, noticeably changing its appearance. High efficiency of cosmetic products
using hyaluronic acid is due to its property to evenly distribute on skin
surface, forming a light coat which actively absorbs moisture from the air.
This facilitates the increase of free water in corneal layer as well as creates
«extra moisture» effect, decreasing water evaporation from the skin surface.
The results
of scientific researches show that hyaluronic acid does not only serve the
purpose of moisturizing. It is supposed that it also stimulates epidermal cells
migration and decreases collagen production. Besides, polymerous net, which is
formed on the skin surface by hyaluronic acid, allows biologically active
substances that are part of cosmetics to stay longer on it. This makes it more
likely for the biologically active substances to penetrate into epidermis.
Hyaluronic acid decreases free radicals formation. Being a natural UV filter,
it prevents hard UV radiation penetration in the range of 280-320 nm.
In
cosmetology, hyaluronic acid is commonly used in the production of preparations
for mesotherapy and contour aesthetic correction. These preparations and
injectable material perfectly moisturize skin, replenish the low level of hyaluronic
acid in the skin, and promotes rapid regeneration and healing of tissues. The
course consisting of several mesotherapy procedures will make your skin fresh,
young and radiant again and help to get rid of fine lines and wrinkles. Since
hyaluronic acid is a natural component, over time it dissolves in your body and
to maintain the achieved effect you need to repeat the rejuvenating procedure
from time to time. As a solution of this problem many professionals offer
chemically stabilized hyaluronic acid. However, it's compatibility with the
skin has not be fully confirmed yet. Sometimes you have to choose between the
long-term effect of hyaluronic acid preparations and their assumed
compatibility.
Hyaluronic
acid is recommended for high quality moisturising gels and creams though it can
practically be used in any cosmetic products, including make-up. The reason for
this is due to the skin's chronological aging, which we can do nothing about.
Internal, chronological aging is largely a consequence of genetics and affects
skin all over the body.
