Hyaluronic Acid is a water-loving molecule that is already found in your skin. A humectant — meaning that it helps preserve or retain moisture — Hyaluronic Acid is a trusted skincare ingredient in hydrating formulas. In fact, one molecule of Hyaluronic Acid can bind up to 1,000 times its weight in water!
Why is Hyaluronic Acid so good for your skin?
Hyaluronic Acid helps replenish skin to boost hydration and improve skin’s elasticity. Since it is already naturally occurring in skin, it is highly compatible with skin making it a trusted and effective skincare ingredient. As you age, Hyaluronic Acid levels decrease and adding a moisturizer or facial serum with Hyaluronic Acid can help plump and hydrate skin.
What does Hyaluronic Acid do?
As a humectant, Hyaluronic Acid draws moisture into the skin and helps maintain moisture levels to visibly smooth and plump skin for ultimate hydration.
What are the benefits of Hyaluronic Acid?
You may notice that Hyaluronic Acid is in your favorite serum or moisturizer but what does it actually do? In addition to boosting hydration, Hyaluronic Acid benefits skin by helping to:
- Immediately smooth rough surfaces
- Provide a protective layer to help skin retain moisture
- Improve skin’s elasticity
What are the uses of Hyaluronic Acid?
Hyaluronic Acid was first used in skincare in the 1960s. In the 1990s, it was included in more cosmetic and skincare formulas.
Is Hyaluronic Acid good for wrinkles and fine lines?
Skin loses moisture and Hyaluronic Acid with age which can cause skin to become dehydrated. When skin is dry or dehydrated, fine lines,wrinkles and rough texture are often more visible. Using hydrating products with Hyaluronic Acid can help visibly improve lines and wrinkles for smoother, younger-looking skin.
Is Hyaluronic Acid also good for your hair?
While Hyaluronic Acid is a trusted skincare ingredient, it also has moisturizing properties for your hair and scalp. Within hair care formulas, Hyaluronic Acid hydrates hair and helps it retain moisture for a smoother and softer appearance.
Is Sodium Hyaluronate the same as Hyaluronic Acid?
Sodium Hyaluronate is actually a form of Hyaluronic Acid. Like Hyaluronic Acid, it works as a moisturizing agent within skincare formulas to help replenish, hydrate and refine skin’s texture. Kiehl’s also formulates some products with Sodium Hyaluronate Filling Spheres which are actually dehydrated molecules which contain Hyaluronic Acid. These spheres rehydrate and absorb water within skin’s surface to help plump and smooth.
What is fragmented Hyaluronic Acid?
Fragmented Hyaluronic Acid is a form of Hyaluronic Acid that is in tiny pieces that are more easily able to penetrate the surface layers of skin.
What skin type should use Hyaluronic Acid?
Every product with Hyaluronic Acid is different so it is important to look for formulas for your skin type and skin needs. Hyaluronic Acid by itself is a lightweight molecule so it can be an effective ingredient in formulas for oily skin. While oily skin may feel greasy, it can actually be dehydrated (lacking in water) and need the moisture boost of a lightweight hydrator. Products with Hyaluronic Acid are often beloved by dry and dehydrated skin types who benefit from hydrating and moisturizing formulas to plump and smooth skin with moisture.

The name "Hyaluronic Acid" comes from the Greek word, "Hyalos" which means "glass." "Uronic" is a term for a sugar that is found in the molecule.
