Hyaluronic Acid
The hydration magnet — helps pull water into skin for a plumper, dewier look.
INCI name: Sodium Hyaluronate / Hyaluronic Acid
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.
What it helps with
- Helps hydrate and plump the look of skin
- Lightweight — layers well under moisturizer and makeup
- Suits most skin types, including oily (hydration is not the same as oil)
Good for
- Dehydrated skin
- Fine lines that look worse when dry
- Glass-skin / dewy routines
- Layering under a moisturizer
Pairs well with
- A moisturizer on top (to seal the water in)
- Niacinamide
- Panthenol
- Ceramides
Watch out
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.
FAQ
Q. 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.
Q. 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.
Q. 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.

The honest note: ingredients help — they don't treat medical conditions. For persistent skin issues, a board-certified dermatologist beats any product swap.
