Hyaluronic Acid: What are its Benefits for Your Skin?
Hyaluronic acid (hyaluronan or HA) is a natural biopolymer. It is a so-called non-sulfated glycosaminoglycan, which is composed of two repetitive derivatives of glucose. Despite its structural simplicity, hyaluronan has a variety of physicochemical properties. The most important characteristic of hyaluronic acid is the fact that its fragments may have a different molecular weight, ranging from several hundred to two million Daltons (and possibly more). It is also well known that hyaluronan fragments of different molecular weight have different biological properties.
A natural substance found in skin
Hyaluronic acid is naturally produced by our body. It is contained in various body parts and fluids such as skeletal tissues, heart valves, lungs, hair follicles, lips, etc. Most of the hyaluronan, however, can be found in skin (about 50%), eye vitreous, umbilical cord, and synovial fluid.
In skin dermis, hyaluronic acid is a core element of the intercellular matrix, which ensures nutrition and other functions of skin cells called fibroblasts that are, in turn, responsible for the production of skin proteins (mainly collagen and elastin). Because hyaluronan can hold up to 1000 times its own weight in water, it plays a key role in skin moisturizing.
Many researchers associate skin aging with a decreasing amount of hyaluronic acid in the dermis, especially high molecular weight HA.
As dermis gradually loses its ability to produce hyaluronic acid, it becomes increasingly more difficult for the skin to remain healthy and maintain a youthful look. Replenishing hyaluronan “stock” needs to be performed regularly since about half of the total hyaluronic acid synthesized by the body gets utilized on a daily basis.
Hyaluronic acid plays a key role in collagen and elastin formation. As collagen and elastin levels decline, the appearance of fine lines and wrinkles becomes more prominent. For the same reason, dehydration, sagging, and loss of elasticity also make it difficult to maintain healthy and beautiful skin. This is the reason why a sufficient level of hyaluronan in the body is essential.
Due to its unique ability to hold large amounts of water (up to 1000 times its weight), the optimal amount of hyaluronic acid in the dermis is crucial for skin moisturizing. As a natural moisturizer, hyaluronic acid contributes to skin plumpness. It also helps dry and oily skin to remain hydrated thanks to hyaluronan's long-lasting ability to retain large amounts of moisture.
Reducing UV damage
Studies have shown that hyaluronic acid is beneficial in reducing oxidation damage to the skin caused by photo-aging. Thanks to the most optimal ratio of low and high molecular weight HA discovered by FEY Cosmetics, active ingredients combined with hyaluronan penetrate through the skin surface and work towards reducing fine lines.
In addition to the above-said, the benefits of hyaluronic acid have to do with skin elasticity and collagen boost. Hyaluronan acts as a cushion and lubricant that reduces damage to the skin and stimulates fibroblasts to produce more collagen as well as other skin proteins.
Hyaluronic acid is also known to be beneficial for treating wounds and burns as it keeps damaged tissue well moisturized. Hyaluronan helps reducing scarring and infection as it releases peptides that inhibit bacterial growth and create an environment that enhances effective tissue repair and proper immune response.
