A sterile, bioabsorbable, bacteria-derived substance intended to be injected into the dermis/hypodermis of the skin, lip submucosa, and/or for supraperiosteal administration to add volume by serving as a space-occupying supplement to the intercellular matrix of connective tissue (dermal filler), typically to correct cutaneous contour deformities (e.g., wrinkles, folds, scars) associated with aging, injury, or degenerative lesions; it includes a local anaesthetic agent (e.g., lidocaine). It typically includes bacterial hyaluronic acid (HA) as the principal constituent and is typically preloaded in a disposable syringe; disposable needle(s)/cannula(e) dedicated to injection may be included.
