Low-molecular weight hyaluronic acid
Hyaluronic acid is a natural compound found in the human body in the form of sodium hyaluronate. It is responsible for maintaining a healthy level of hydration.
Hyaluronic acid is a natural component of human skin. It is known for its ability to effectively bind water. In the human body, it serves a structural purpose and fills the extracellular spaces as a water reservoir.
The amount of hyaluronic acid decreases with age; from the age of 25 to 50, its quantity drops by as much as 50%, and around the age of 80, it nearly disappears. As a result, the skin regenerates at a slower rate, becomes dry and loses its tone. Dynamic wrinkles begin to appear.
Hyaluronic acid is one of the most sought-after ingredients in cosmetics, since it is expected to deeply hydrate the skin. It has powerful rejuvenating and smoothing properties. Its presence in the human body allows the skin to maintain a healthy level of hydration. It supports the structural proteins of the skin – collagen and elastin – and stimulates their synthesis. Hyaluronic acid fills the extracellular spaces and creates an invisible, thin barrier that protects the skin against water loss. Furthermore, it forms a natural protective filter that shields the skin from damage and bacteria.
Hyaluronic acid is an extremely gentle ingredient, so it can also be used on sensitive skin. It is a perfect anti-ageing ingredient and support for young skin.
Who should use cosmetic products that contain hyaluronic acid?
Hyaluronic acid is an extremely gentle ingredient, so it can also be used on sensitive and redness-prone skin. Cosmetic products that contain hyaluronic acid should be used on young skin as protection against premature ageing, and as a shield for skin exposed to the sun and other harmful external factors that negatively affect its hydrolipidic barrier. It is a perfect ingredient for menopausal women who experience a drop in their skin’s hydration levels. It brings relief to dry and dehydrated skin. It is also recommended as eye protection for those who work in air-conditioned rooms and spend long hours in front of the computer.
Immediate action of hyaluronic acid
Once a cosmetic product containing hyaluronic acid is applied, its moisturising effect can be felt immediately. It instantly soothes and hydrates the skin and fills it from the inside. When used regularly, hyaluronic acid visibly smooths the skin’s texture, minimises the appearance of fine lines and reduces the skin’s tendency for irritation. It visibly increases the skin’s firmness and elasticity, eliminates dark circles under the eyes and improves the skin’s general condition, leaving the face looking well rested.
What is the difference between high- and low-molecular weight hyaluronic acid?
The molecular weight of hyaluronic acid affects its mechanism of action. Due to the size of its molecules, high-molecular weight hyaluronic acid is unable to penetrate the stratum corneum and hydrates only the upper layers of the skin.
On the other hand, low-molecular weight hyaluronic acid has the ability to penetrate deep into the skin due to the smaller size of its molecules. It reaches the dermis to fully hydrate it and visibly reduces the appearance of wrinkles by “filling them in” from the inside. It also improves the skin’s elasticity and its hydration levels.
