NASHA-L

NASHA-L is a **non-animal stabilized hyaluronic acid** injectable gel formulation containing cross-linked hyaluronic acid and lidocaine, used primarily as a soft-tissue filler in aesthetic medicine. In published comparative studies and regulatory materials, NASHA-L refers to the **firm NASHA technology hyaluronic acid gel corresponding to Restylane Lyft with lidocaine**, a 20 mg/mL hyaluronic acid product generated by *Streptococcus* fermentation, chemically cross-linked with BDDE and supplied as a sterile injectable gel. Its therapeutic effect is primarily **mechanical tissue augmentation and volume restoration** rather than receptor-mediated pharmacology, with lidocaine included to reduce injection-associated pain. The product lineage was originally developed by Q-Med and is now part of the Galderma Restylane portfolio, with approvals and commercial use in facial contouring, correction of facial folds and wrinkles, and hand augmentation depending on jurisdiction.
