Hyaluronic Acid 101: Your Most Asked Questions, Answered

What's in a name? As it turns out, when it comes to hyaluronic acid, not much. Here are your top FAQs on the seemingly ubiquitous skincare ingredient with the arguable misnomer: 

Q. What is hyaluronic acid?
A. 
Contrary to its name, hyaluronic acid is not an acid. In unscientific terms, it’s a clear, sugary goo that occurs naturally in your body, acting as a cushion for our skin, nerves and joints.

In skincare, it’s used as a humectant—because it can hold water really efficiently. No surprise: This large molecule can hold up to 1,000x its weight in water.

Q. How does hyaluronic acid work?
A. A lot of people think this humectant absorbs water, but it actually forms hydrogen bonds with water in formulas (like in the Resurfacing Compound and The SUPER). When applied, it attracts water and draws moisture into the skin. 

Q. I’ve heard it can actually suck moisture from my skin. Is this true?
A. Not at all! Forget the word “acid,” because it’s perfectly fine for those with sensitive or breakout-prone skin. Whether in your serums (ahem, Compounds) or moisturizers, hyaluronic acid is an ingredient integral to supple, hydrated skin.

Q. So what’s the result? No dryness, really?
A. Hyaluronic acid keeps your skin’s moisture levels optimized, boosting collagen and hydrating to visibly smooth and plump skin. Not only that, it diminishes the look of wrinkles and fine lines.

Q. Are there different kinds of hyaluronic acid?
A. A hyaluronic acid molecule can be arranged in different ways to achieve various activities in the skin, from cross-chained to hydrolyzed varieties and beyond.

Enter what makes The SUPER Hydrator so super: We use five unique HAs, including that unique dehydrated Long-Chain Hyaluronic Acid in the HYDRA-SIREN, for deep-level hydration you won’t get from any other moisturizers.

Q. Which other U Beauty products feature hyaluronic acid?
A. The SUPER and Resurfacing Compound both contain hyaluronic acid. But that doesn't mean it's redundant when you use The Duo

The SUPER features five different hyaluronic acid types to reach different skin depths and compositions, ensuring the skin holds onto moisture longer (since hydration is the main goal here). While the Compound contains one for a visible collagen boost and reduction in fine lines and wrinkles.
