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 liters of water!
Note: 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)!
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 (as detailed in this article, 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.
