Quick Summary
What is Hyaluronic Acid / Sodium Hyaluronate?
Hyaluronic Acid (HA) is a naturally occurring sugar-like molecule found in skin and joints. In skincare, it’s used because it can bind water and help skin look more hydrated and plump.
Sodium Hyaluronate is the salt form of hyaluronic acid and is very commonly used in cosmetics. On ingredient lists, you may see either name (or both). Functionally, both are used to support hydration and a smoother look.
- INCI: Hyaluronic Acid, Sodium Hyaluronate (you may see one or both)

How to use it correctly
Hyaluronic acid works best when you give it water to bind to and then “seal” it in with moisturizer. This is especially important if you live in a very dry climate.
- Typical use level: commonly 0.1% to 2% in serums and moisturizers.
- Frequency (AM/PM): AM and PM.
- Routine order: Cleanser → (toner/essence) → HA serum → moisturizer → SPF in the morning.
- Application tips: Apply on slightly damp skin, then follow with moisturizer to lock in hydration.
Compatibilities & combinations
Pairs well with: Ceramides (barrier support), Peptides (skin-supporting routines), and Niacinamide (helps strengthen the barrier and improve overall texture).
Best to avoid combining with: No common “must-avoid” pairings. If using exfoliating acids or retinoids, HA can help offset dryness by improving comfort and hydration.
