Sodium Hyaluronate
Sodium Hyaluronate (Hyaluronic Acid)
A water-holding ingredient that pulls moisture into skin.
Sodium Hyaluronate binds water to skin so it stays hydrated and looks plumper.
In three sentences
Sodium Hyaluronate is a water-holding ingredient your skin makes naturally. It pulls water into your outer skin layer and helps skin stay moist. Low-weight forms may work better than regular forms.
What it does
Think of it as a sponge in your outer skin that soaks up and holds water.
Sodium Hyaluronate is a carbohydrate that binds water to skin. It works by pulling moisture into the outer skin layer and helping skin hold onto it. The ingredient comes in different molecular weights, which changes how it works.
Studies report that low-molecular-weight hyaluronic acid was superior to standard forms for improving skin hydration in elderly patients with dry skin. The same study found no difference in water loss from skin between the two molecular weight forms.

FAQ
- Does hyaluronic acid make skin feel sticky?
- Hyaluronic acid is not sticky on its own. In a serum, it may feel a bit tacky while wet. Once dry, it feels moist but not oily.
- Can I use hyaluronic acid if I have oily skin?
- Yes. It adds water, not oil. Even oily skin can be dry deep down, and water helps your skin barrier. Use a light serum or toner.
- Do I need to use hyaluronic acid every day?
- It is safe to use every day. Put it on clean, damp skin and seal it with a moisturizer. Daily use keeps skin wet and steady.
