Hyaluronic acid is a naturally occurring biopolymer widely used in skincare and pharmaceutical formulations for its exceptional hydrating and viscoelastic properties. It functions as a powerful humectant, attracting and retaining moisture in the skin while enhancing formulation texture and stability. This ingredient is biocompatible, non-toxic, and effective across a range of pH levels. Hyaluronic acid is stable under various environmental conditions and demonstrates good compatibility with other active ingredients, making it a versatile component in both aqueous and emulsion-based systems
