High-quality strains are carefully selected and fermented in a controlled liquid environment under strict temperature, pH, and nutrient conditions to achieve efficient hyaluronic acid synthesis.

Multi-stage centrifugation and filtration remove bacteria and impurities, yielding a fermentation supernatant containing hyaluronic acid.

Multiple purification techniques are employed to effectively remove proteins and impurities, improving product purity and safety.

The hyaluronic acid solution is further purified using membrane separation and concentration techniques to ensure molecular structure stability and consistency.

Low-temperature spray drying or vacuum drying technology is used to convert liquid hyaluronic acid into a uniform powder, maintaining its activity and physicochemical properties.

The finished powder undergoes fine sieving and homogenization to ensure uniform particle size and good flowability.

After passing rigorous quality inspections (purity, microorganisms, heavy metals, etc.), the products are aseptically packaged to ensure they meet cosmetic-grade standards.
