“Closest ingredient-family evidence: topical 0.1% hyaluronic acid of multiple molecular weights improved skin hydration and elasticity; 50–130 kDa HA also reduced wrinkle depth versus placebo.”
8D Hyaluronic Acid
Cosmetics
Code: 8238
Premium 8D multi-hyaluronic gel combining multiple HA sizes and derivatives for intensive water-based hydration formulas.
8D Hyaluronic Acid is a high-concentration multi-HA gel for premium hydration formulas.
It combines sodium hyaluronate molecular-weight fractions with hydrolyzed HA, cationic HA, acetylated HA and sodium hyaluronate crosspolymer in a water/propanediol base.
The gel format allows formulators to add a broad HA system directly into water-based formulas without pre-hydrating multiple powders.
Product Description: The system is designed to cover multiple hydration mechanisms: low molecular weight HA for a light fast hydration feel, larger HA for surface water binding, cationic HA for better substantivity, acetylated HA for improved skin affinity, and crosspolymer HA for longer moisture-retaining film feel.
Use this product when the formula is positioned as a premium hyaluronic serum, mask, gel cream or intensive hydration product. It is a concentrated ingredient and must be diluted into the finished formula.
Usage: Suitable for premium hydrating serum, ampoule, gel cream, mask, sleeping mask, eye gel, lotion and cream.
Mixing method:
- Add directly into the water phase or cool-down phase and mix until uniform.
- Maintain final formula pH about 3-9.
- If viscosity is high, pre-dilute with part of the water phase before adding to the main batch.
Usage rate: 1-20%. Typical: 2-5% for normal/dehydrated skin formulas, 5-10% for dry skin formulas and 10-20% for intensive hydration products.
Product characteristics: Cloudy viscous gel.
Solubility: Water soluble; disperses directly into water-based formulas.
Storage: Keep closed in a cool place away from heat and sunlight. Refrigeration is acceptable for long-term storage.

“Closest ingredient-family evidence: low-molecular-weight HA moisturizer improved skin hydration in elderly xerosis more than high-molecular-weight HA or vehicle, supporting the small-HA component of 8D HA.”
“Closest ingredient-family evidence: a topical HA serum produced significant facial hydration and photoaging appearance benefits with good tolerability.”
