Hyaluronic Acid
The hydration magnet — helps pull water into skin for a plumper, dewier look.
What it is
Hyaluronic acid (HA) is a humectant your body already makes. In skincare it acts like a sponge, drawing water toward the skin. On labels it often appears as Sodium Hyaluronate (a smaller, more stable form) or as a blend of different molecular weights.

HA pulls water from wherever it can. In very dry air, apply it to damp skin and always seal with a moisturizer — otherwise it can draw water out of deeper skin and leave you feeling tighter, not more hydrated.
Is sodium hyaluronate better than hyaluronic acid?
They are closely related — sodium hyaluronate is a salt form that is smaller and more stable, so it is common in formulas. For most people the practical difference is minor; a blend of weights is a good sign.
Can oily skin use hyaluronic acid?
Yes. Hydration and oil are different things — oily, dehydrated skin is common. HA is lightweight and usually a good fit; just seal it with a light gel moisturizer.
Should I apply hyaluronic acid to wet or dry skin?
Slightly damp skin, then lock it in with a moisturizer. On bone-dry skin in dry air, HA has less water to grab and can feel tight.
Ingredients help the look and feel of skin; they do not treat medical conditions. No brand paid to be here. Skincare information, not medical advice — for a persistent concern, see a board-certified dermatologist.
