Features

Ultra-low molecular weight structure (3–5 kDa)

Small molecular size allows for easier diffusion within the stratum corneum, providing deeper hydration.

Cosmetic-grade high purity

Manufactured strictly according to cosmetic raw material quality standards, with excellent impurity control, ensuring high safety and batch stability.

Rapid absorption and refreshing feel

Excellent water solubility, less likely to cause stickiness, contributing to a better user experience in end products.

Strong formulation compatibility

Remains stable within the standard pH range of cosmetics, allowing for flexible application in various dosage forms and formulation systems.

Functions

With its ultra-low molecular weight, this hyaluronic acid helps enhance deep hydration of the skin, improves dryness, and increases skin softness and smoothness. When used in combination with medium and high molecular weight hyaluronic acid, it can create a multi-layered moisturizing system, meeting the formulation design requirements of modern skincare products for "layered hydration."

Applications

  • Serums and essence formulations
  • Deeply hydrating and anti-aging skincare products
  • Soothing and repairing formulas
  • Creams, lotions, gels, and other daily chemical products
