Ingredient Deep Dive: What Does Hyaluronic Acid Do
Hyaluronic acid is a powerful skincare ingredient with a remarkably simple primary function: to hydrate the skin by binding and retaining water. It plays a key role in The Ordinary’s formulations and is one of the focal points of anyskincare regimen.
What is Hyaluronic Acid?
Hyaluronic acid is a naturally occurring substance throughout the body, found in the skin, eyes, joints, and muscles. It’s considered one of the most well-known ingredients for hydration and healthy-looking skin.
Our bestsellingHyaluronic Acid 2% + B5 (Original Formulation)targets issues like these, improving skin elasticity and working to hydrate and plump the appearance of fine, dry lines immediately.
Choosing the Right Hydrating Serum for You
When choosing a new hydrating serum to add to your regimen, it’s important to consider your personal product preferences, the skin concern/s you want to target, and what products/ingredients you already have within the regimen.
If you prefer lightweight products, you may want to explore water based hydrating serums like the three mentioned above. If you have severely dry skin, you may want to explore thinker or heavier hydrating products like oils or creams. The Ordinary offers a wide range of hydrators to allow for a more personalized hydration skincare regimen.
Explore The Ordinary's range of hydrating serums to find the perfect match for your skin's needs.

We formulated our Hyaluronic Acid 2% + B5 Serum (with Ceramides) to deeply penetrate the skin’s surface layers, providing intense hydration.

                What’s the difference between the original Hyaluronic Acid 2% + B5 Serum and the new formulation with Ceramides?
The Hyaluronic Acid 2% + B5 (Original Formulation) contains 4 molecular weights of hyaluronic acid to hydrate, alongside vitamin B5 to support the skin’s moisture barrier. The original formulation has a rich serum texture and smooths the skin.
Hyaluronic Acid 2% + B5 (with Ceramides) features 5 types of HA for multi-layer instant plumping hydration, added ceramides for skin barrier support, and the same vitamin B5 present in our original formulation. It has a non-tacky serum texture that is more lightweight than the Original formulation.
