Frequently Asked Questions (FAQ) — Low Molecular Weight Sodium Hyaluronate (HA)

1. What is Low Molecular Weight Sodium Hyaluronate?

Low Molecular Weight Sodium Hyaluronate (HA) is a smaller-sized hyaluronic acid derivative, typically below 300 kDa, designed to penetrate deeper into the skin for long-lasting hydration, anti-wrinkle benefits, and enhanced elasticity.

---

2. What are the main functions and benefits?

It provides deep moisturizing, anti-aging, and skin-repairing effects. Its smaller molecular size allows it to reach deeper layers of the epidermis, improving skin texture, smoothness, and firmness while preventing transepidermal water loss (TEWL).

---

3. How does it differ from Medium or High Molecular Weight HA?

• Low Molecular Weight (≤300 kDa): Deep skin penetration, intense hydration, anti-aging.

• Medium Molecular Weight (800–1500 kDa): Balanced hydration and film-forming.

• High Molecular Weight (≥1600 kDa): Surface moisturizing and protective barrier formation.
  Low molecular weight HA focuses on deep hydration and rejuvenation, making it ideal for anti-aging products.

---

4. What cosmetic applications is this ingredient suitable for?

It is widely used in:

• Facial serums and essences

• Anti-aging creams

• Moisturizers and lotions

• Eye creams

• Sheet masks and hydrating gels

• Hair and scalp care products

---

5. What are the technical advantages of your product?

• High purity and low endotoxin content

• Excellent solubility and stability

• Strong bioactivity and skin compatibility

• Produced in ISO9001, HACCP, GMP, and ISO14001-certified facilities

• Non-animal, non-GMO fermentation source

---

6. What is the purity and specification of this HA grade?

• Purity: ≥95%

• Molecular Weight Range: ≤300 kDa

• Protein: ≤0.1%

• Endotoxin: ≤0.5 EU/mg

• Appearance: White to off-white powder, odorless, highly soluble in water

---

7. Is it suitable for food or nutraceutical applications?

Yes. It can be used in nutraceuticals and dietary supplements to support joint health, skin hydration, and anti-aging from within, depending on local regulatory compliance.

---

8. How should Low Molecular Weight HA be stored?

Store in a cool, dry, and well-ventilated place (below 25°C). Protect from light and moisture. Keep the container tightly sealed. Shelf life: 24 months when properly stored.

---

9. Is it compatible with other cosmetic ingredients?

Yes. It shows excellent compatibility with vitamins, peptides, collagen, botanical extracts, glycerin, and surfactants, maintaining stable viscosity and clarity in formulations.
