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

1. What is Medium Molecular Weight Sodium Hyaluronate?

Medium Molecular Weight Sodium Hyaluronate (HA) is a natural, water-soluble biopolymer derived from hyaluronic acid. With a molecular weight range of 800–1000 kDa or 1200–1500 kDa, it offers balanced hydration, viscosity, and skin absorption, making it suitable for a wide range of skincare and personal care formulations.

---

2. What are the main functions of this HA grade?

This HA provides deep moisturization, film-forming ability, and smooth texture enhancement. It retains moisture in the skin, improves elasticity, and supports the stability of emulsions in cosmetic products.

---

3. What is the difference between low, medium, and high molecular weight HA?

• Low molecular weight (≤300 kDa): Penetrates the epidermis for deep hydration.

• Medium molecular weight (800–1500 kDa): Provides surface hydration, smooth texture, and balanced absorption.

• High molecular weight (≥1600 kDa): Forms a protective film on the skin for long-lasting moisture retention.
  Medium molecular weight HA offers the best balance between absorption and moisturizing durability.
