Hyaluronic acid is frequently used as an ingredient in skin care products due to its "unique and special capacity in retaining water."
Did you know that it is also naturally produced by our bodies? This information is about how hyaluronic acid is produced, the relationship between hyaluronic acid, skin aging and how to improve skin quality through its application.
WHAT IS HYALURONIC ACID?
Hyaluronic Acid is an essential chemical that decreases with age. Just like collagen, the body produces hyaluronic acid, a naturally occurring polysaccharide located in the skin, joints, and eyes. Hyaluronic acid is one of the principal essentials for keeping the skin hydrated thanks to its ability to bind and retain water molecules. Well-hydrated skin is necessary to reinforce the shield over the skin allowing it to retain moisture and protect against bacteria.
About how hyaluronic acid is produced in the body, research has shown that the production of hyaluronic acid decreases with age. This results in a gradual increase in dehydration, loss of elasticity and dullness.
WHAT DOES HYALURONIC ACID DO TO OUR SKIN?
Replenishing levels of hyaluronic acid in the skin can be safely achieved through hyaluronic acid skin care (topical application) in a variety of forms, from hyaluronic acid serums to moisturizers and dermatological processes such as facials.
In cosmetics, hyaluronic acid is often used in different molecular forms: the larger the form, the less it penetrates, offering surface-level hydration. The smaller the molecules, however, the deeper the absorption into the surface layers of the skin – improving skin health. The main action of the HMW-HA polymer is film forming and it reduces evaporation of water from the skin and thus possesses an occlusive effect.
