Bellafill (Suneva), a dermal filler approved earlier for correction of nasolabial folds, has now also been approved by the FDA for correction of moderate to severe, atrophic, distensible facial acne scars on the cheek in adults ≥21 years old. It is the only dermal filler approved in the US for correction of facial acne scars.

Some Medical Letter consultants have suggested that our recent article on dermal fillers (Med Lett Drugs Ther 2007; 49:39) should have included stronger warnings about the risk of fillers that are not biodegradable, such as Artefill. The polymethylmethacrylate (PMMA, the same material that makes up Plexiglas) beads in Artefill can over time, even with the best technique, cause foreignbody granulomas and hypertrophic scarring, which may require surgical removal. Granulomas and nodules have been especially frequent when Artefill was injected into the lips. Complications are less likely with hyaluronic acid products such as Hylaform, Juvéderm or Restylane.

An injectable gel of hyaluronic acid (Restylane) has been approved by the FDA for correction of moderate to severe facial wrinkles and folds, such as nasolabial folds. Manufactured by Q-Med AB, a Swedish company, it has been used outside the US since 1996.
