Ingredient review
Sodium Oleoyl Hyaluronate
INCI: Sodium Oleoyl Hyaluronate
A gentle, modified hyaluronic acid that sticks to skin longer for lasting hydration without irritation.
In plain English
Sodium Oleoyl Hyaluronate is a hybrid molecule that combines hyaluronic acid (a natural moisture magnet) with oleic acid (a fatty acid from olive oil). This tweak helps the ingredient cling to your skin better than plain hyaluronic acid, so it doesn't rinse off as easily and keeps delivering moisture over time. It's a modern upgrade for people who want deep hydration without the sticky feel.

Quick decision guide
Useful, but context matters
Sodium Oleoyl Hyaluronate is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Sodium Oleoyl Hyaluronate.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A semi-synthetic derivative of hyaluronic acid, where a fatty acid chain (oleic acid) is attached to the hyaluronic acid backbone. This modification improves its ability to bind to the skin's surface and resist being washed away.
How it works
The oleic acid tail anchors the molecule to the lipid layer of your skin, while the hyaluronic acid head pulls in and holds water. This dual action creates a long-lasting moisture film that stays put even after cleansing, helping to keep skin plump and hydrated throughout the day.
Pros
Enhanced skin adhesion
The oleic acid tail helps the molecule stick to your skin longer, so you get sustained hydration even after washing your face.
Gentle for sensitive skin
Unlike some active ingredients, this modified hyaluronic acid is very well-tolerated and unlikely to cause stinging or redness.
Cons and cautions
Less research than standard HA
While promising, there are fewer peer-reviewed studies on this specific derivative compared to plain hyaluronic acid, so long-term data is still emerging.
May need a moisturizer over it
In very dry environments, the water it holds can still evaporate if you don't seal it in with an occlusive cream or oil.
Best for
- Anyone seeking deeper, longer-lasting hydration
- People with normal to dry skin who find plain hyaluronic acid evaporates too quickly
Use caution if
- Those with a known allergy to oleic acid or olive oil derivatives (rare)
Usage tips
Safety summary
Sodium Oleoyl Hyaluronate is considered safe for topical use in cosmetics. It has low irritation and comedogenic potential, making it suitable for most skin types. As with any ingredient, patch test if you have very sensitive skin or known allergies to fatty acids.
Research notes
Research indicates that fatty acid-modified hyaluronic acid derivatives improve skin retention and hydration compared to unmodified HA. However, most studies are sponsored by ingredient manufacturers, and independent clinical data is still limited. The evidence supports its use as a humectant, but more long-term studies are needed.
Common label clues
- Typical concentration
- 0.1% to 1%
- Regulatory status
- Approved for cosmetic use in the EU, US, and other major markets. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Serums, Moisturizers, Eye creams, Sheet masks
- Environmental note
- Produced via chemical modification of bio-based hyaluronic acid and oleic acid. Generally considered low environmental impact, but specific sourcing varies by manufacturer.
Good to know
- This ingredient is often found in 'hyaluronic acid' serums that claim 'time-release' or 'long-lasting' hydration.
- It is not the same as standard hyaluronic acid; check the ingredient list if you specifically want the classic version.
