What is Hyaluronic Acid in Skincare?

Hyaluronic acid (HA) is a humectant—meaning it helps attract and retain water. Reviews of topical HA describe how its effects vary by molecular weight: larger HA can form a surface film that supports hydration, while smaller forms are often used for different sensorial and potential penetration behavior (dependent on the full formulation).

How Hyaluronic acid Works in the Skin

Topical HA primarily improves skin quality by increasing hydration and supporting a smoother “plumped” look. A randomized trial comparing different topical HA molecular weights in older adults with dry skin underscores the “molecular weight matters” concept in real-world hydration outcomes (sample size limitations apply).

Benefits of Hyaluronic acid

Expect hydration support, improved look of dehydration fine lines, and better “bounce” when HA is used consistently—especially when followed by a moisturizer that seals hydration in.

Who is Hyaluronic acid Best For?

Most skin types can use HA, particularly if dryness, tightness, or dehydration lines are present. Dr. Zenovia positions HA as especially helpful for dry, sensitive, and aging skin when paired with peptides and barrier lipids.

What Makes Our Hyaluronic acid Different

Not all hyaluronic acid hydrates the same way—molecular weight matters. That’s why we use multiple molecular forms of Hyaluronic Acid to support more continuous, comfortable hydration across skin’s layers.

Our formula features fractionated (multi-weight) Hyaluronic Acid—ultra-small and varying-size HA molecules designed to help draw in moisture and replenish hydration beyond the surface for that “bouncy,” plumped look.

At the same time, we pair it with a high molecular weight Hyaluronic Acid approach that primarily stays closer to the skin’s surface, forming a thin protective hydration layer that helps keep moisture from escaping—so skin feels hydrated now and stays comfortable later.
