So why is hyaluronic acid such a big deal? The magic of this ingredient lies in its ability to retain moisture; it’s considered to have a greater capacity to hold moisture than any other natural or synthetic polymer. In fact, one gram of hyaluronic acid is able to hold up to six litres of water!
This is important with regard to aging because one of the hallmarks of youthful skin is its moisture content. As we age, our skin loses moisture, resulting in a loss of firmness and pliability.
This does not mean that everyone’s skin becomes dry with age; it simply means that skin lacks the amount of moisture it had in its youth due to sun damage and/or other factors. Without question, you can still have oily skin in your 60s (perhaps just not as oily as it was in your 20s)!
Hyaluronic acid can improve your skin’s moisture content and at the same time strengthen skin’s barrier; that is, the outer layers of your skin. A healthy barrier looks and feels softer, smoother, and plumper—all hallmarks of younger-looking skin! But, with hyaluronic acid, that’s not all you get—there are many additional benefits beyond just a more youthful appearance.
We know that just about everything, from sun damage and acne to sensitive skin and rosacea, can lead to a damaged barrier, so repairing skin’s barrier with skin-identical ingredients, like hyaluronic acid, can go a long way toward fixing, or at least minimizing, those issues, which means it’s helpful for all skin types. Its lightweight texture isn’t an issue for oily skin, and it’s gentle enough that it isn’t a problem for sensitive skin.
Even better, Hyaluronic acid also provides antioxidant defense against free-radical damage, and reduces inflammation. Now that’s what we call a multitasking anti-aging ingredient!
