Hyaluronic acid is a unique active ingredient for skin hydration. We take a look at its moisturizing properties and how it works to plump up skin.
The plumping up effect of hyaluronic acid
Hyaluronic acid is an ingredient that’s found in many creams and also found naturally within the skin. Because of its structure it has the ability to retain and preserve moisture and, despite the word ‘acid’ in the name, it doesn’t exfoliate skin, but rather plumps it up.
CAN HOLD1000 Xits weight in water
Hyaluronic acid has the capacity to hold 1,000 times its weight in water because of its hygroscopic properties, allowing it to draw in water from the environment.
Hyaluronic acid acts as a molecular sponge, which makes it an invaluable ingredient in skincare, and in addition, it creates a barrier on the skin, making skin softer, smoother and more moisturized. Hyaluronic acid gives skin that plumping, dewy effect. The hyaluronic acid molecule swell up and give skin cells volume, which in turn fills in lines and makes skin look supple.
Hyaluronic acid holds moisture in the spaces between the cells of the skin, helping it to stay plump. Hyaluronic acid helps soften fine lines, making skin appear firmer and smoother. It revitalizes skin’s outer layers so they look and feel softer and glowingly hydrated, while improving skin’s texture.

How hyaluronic acid works against the signs of aging
In the skin, levels of hyaluronic acid naturally decrease every year, resulting in dermal dehydration and leading to wrinkles and as we age, the body’s ability to produce hyaluronic acid naturally slows down. This means that skin loses the ability to preserve moisture, resulting in a loss of firmness, pliability and plumpness.
In addition, when skin is dehydrated, this can manifest in more visibly fine lines, sagging or slack skin and dullness.
Topically applied hyaluronic acid, with its powerful hydrating properties, can help slow down and correct the effects of aging, leaving skin moisturized and smoother. These hydrating abilities and their subsequent effects make hyaluronic acid such a beneficial ingredient to look out for in your skincare products.
