Hyaluronic acid in cosmetics and in dietary supplements
Did you know you can increase your own hyaluronic acid by using hydrolyzed collagen?
Hyaluronic acid is currently one of the most wanted anti-aging ingredients on the market in addition to collagen of course. It has numerous positive effects, including healthier skin, wound healing and relieving joint pain.
What is hyaluronic acid?
Hyaluronic acid or hyaluronan is a polysaccharide (many carbohydrates linked together) composed of D-glucuronic acid and N-acetylglucosamine. It is a very hydrophilic molecule (it loves water) and is very important in maintaining tissue mobility. It has significant ability to attract and bind water molecules. It has the power to increase skin elasticity by 20 percent and one great reputation of keeping the eyes moist and the joints lubricated. In addition to excellent water retention, hyaluronic acid is also biodegradable and non-immunogenic (does not cause allergic reactions).
Where is hyaluronic acid found?
The human body contains about 15 g of hyaluronic acid and 50% of the total is found right in the skin. Studies indicate that one-third of the total hyaluronic acid mass decompose and rebuilt each day (link to the study here).
How are skin aging and hyaluronic acid related?
Human cells lose their ability to build hyaluronic acid with age. Reduced production is reflected in skin aging, dry skin and the appearance of wrinkles. With age, the moisture of the skin decreases, it becomes rougher and less elastic, which is due to the loss of hyaluronic acid.
The use of hyaluronic acid in cosmetics and dietary supplements
Hyaluronic acid plays an important role in cosmetic products due to its powerful ability to bind huge amounts of water. We are talking about a thousand times more water than its own mass! Hyaluronic acid moisturizes skin, reduces appearance of wrinkles, replenishes cell moisture and also speeds wound healing. Topically (externally) applied product with hyaluronic acid reduces the signs of skin aging.
2 ypes of hyaluronic acid
There are two types of hyaluronic acid. High molecular weight hyaluronic acid moisturizes skin by forming a film on the skin's surface and thus preventing water loss. Low molecular weight hyaluronic acid can penetrate into the skin where it supports its natural moisturizing mechanisms and provides a better skin surface texture.
Recent studies have shown better efficacy of low molecular weight hyaluronic acid compared to high molecular weight. Low molecular weight hyaluronic acid helps skin to regenerate and slow down skin ageing.
We can increase the production of our own hyaluronic acid
Taking dietary supplements containing collagen hydrolysates can limit the harmful effects of UV rays that reduce the elasticity of tissues and skin. Collagen hydrolysates increase the production of hyaluronic acid in tissues and skin. The combination of collagen and hyaluronic acid helps maintaining skin elasticity and reduces water loss, which is an important factor in preventing the visible signs of aging.
