Is hyaluronic acid hydrating?

Immediate Answer: Yes, but it works differently than you might think. Hyaluronic acid doesn't add moisture to your skin—it holds moisture in your skin, plumping fine lines and improving texture temporarily while other ingredients work on long-term changes.

The Science: Hyaluronic acid is a humectant—it attracts and binds water molecules (up to 1000x its weight in water). When applied to skin, it draws moisture from the air and deeper skin layers to the surface, creating a plumping effect. This effect is temporary—it lasts as long as the hyaluronic acid film remains on your skin.

Important distinction: Hyaluronic acid doesn't "hydrate" your skin permanently. It temporarily improves the appearance of hydration while your skin's natural moisture barrier handles actual long-term hydration.

How Nordic Formula Uses Hyaluronic Acid: Power Glow Serum, Advanced Face Repair, and Daycream Defence Repair SPF 50 all contain hyaluronic acid for its plumping benefits while stronger actives (peptides, retinol, niacinamide) work on structural changes. The Daycream contains both hyaluronic acid and sodium hyaluronate—two forms that work at different skin depths for comprehensive hydration throughout the day. The combination across all products—immediate plumping + long-term structural support—produces results that feel and look better week by week.

Pro Tip: Apply hyaluronic acid to damp skin, then seal with moisturiser. If you apply it to completely dry skin, it can actually draw moisture out of deeper layers. Always follow with occlusive moisturisers to maintain the hydration benefit.
