Dermal tissue reconstructive material, microbe-derived

This category includes sterile, bioabsorbable materials derived from bacteria that are injected into the skin or underlying tissues to add volume and correct contour irregularities such as wrinkles, folds, or scars. These substances function as dermal fillers by integrating with the body's connective tissue matrix and are made primarily from bacterial hyaluronic acid without added anesthetic agents.

Devices in this category are supplied as prefilled, disposable syringes, often with dedicated needles or cannulas for injection, and are intended for single use. They are regulated as implantable medical devices based on their mechanism of action and interaction with tissue, with classification determined by national authorities according to risk and duration of use.
