At ORY®, we believe you should know what’s in your products and why. This page lists the published research behind what we say about sodium hyaluronate. Each section starts with our claim, then tells you how well the research supports it, then lists the sources so you can read them yourself.
How to read this page Supported — backed by peer-reviewed research or official safety reviews. Supported, with caveats — the research points this way, but mostly from laboratory or animal studies, or at different strengths than ORY® uses. Limited evidence — little or no published research yet. We say so openly. |
1. General Description and Role
Claim: Sodium hyaluronate is the sodium salt of hyaluronic acid, the skin’s main water-binding molecule. In ORY® products, it helps skin and hair hold moisture, so skin looks plumper and smoother. |
Verification: Supported. The Cosmetic Ingredient Review (CIR) Expert Panel found hyaluronic acid, potassium hyaluronate, and sodium hyaluronate safe as used in cosmetics.

2. Composition and Production
Claim: Cosmetic sodium hyaluronate is made by bacterial fermentation (vegan) and supplied in different molecular weights, from large molecules that form a surface film to smaller fragments. |
Verification: Supported. Its chemistry and production are well documented.

4. Hair and Scalp Suitability
Claim: In haircare, sodium hyaluronate helps hair and scalp feel moisturized. |
Verification: Limited evidence. We found no clinical studies of sodium hyaluronate on hair. ORY® haircare products are not intended to treat scalp conditions.

5. Benefits
Claim: Sodium hyaluronate helps skin look plumper, smoother, and more hydrated. |
Verification: Supported, with caveats. In a 60-day study, creams with hyaluronic acid of different molecular weights improved hydration and elasticity, and lower-molecular-weight forms reduced the look of wrinkle depth more. Effects depend on continued use.

6. Use Across ORY® Product Lines
Claim: Sodium hyaluronate is used in ORY® Skincare, Haircare, and Cosmetics. It is not used in bar soap. |
Verification: Supported. It rinses away in bar soap, so it has no use there.
| Product line | Typical level | How ORY® uses it |
| Skincare | 0.1–2% | Serums, toners, essences, moisturizers, sheet masks, and eye creams. |
| Haircare | 0.1–0.5% leave-in; 0.05–0.2% rinse-off | Leave-ins, curl creams, hair masks, and scalp serums. |
| Cosmetics | 0.1–1% | Primers, foundations, setting sprays, and lip balms. |

Verification: Supported. We list these limits so you have the full picture:
- Temporary effect. Requires continued use.
- Dry air. Seal with a moisturizer or oil.
- Preservation. Solutions support microbial growth.
- Cost. Low-molecular-weight grades are premium.
- Not a filler. Topical use is unrelated to injectable fillers.

9. Safety Notes
Claim: Patch test before use; for external use only. |
Verification: Supported. Follow these precautions:
- Patch test any new product on a small area for 24–48 hours before full use.
- Humectants work best when followed by a moisturizer or oil, especially in dry air.
- Stop use if redness, burning, itching, or rash occurs, and talk to a healthcare provider.
- For external use only. Avoid the eyes. Do not use on broken or seriously damaged skin.
- If you are pregnant, nursing, have a medical condition, or are buying for a child, ask a healthcare provider before use.
