Hi There Thank you for your question.Under eye festoons are difficult to be fair and I have not seen any good treatment of them. I have seen a number of plastic surgeons promise good results then fail to deliver.Malar mounds can also be challenging but do respond to the 8 point face lift done properly as taught by Mauricio de Maio. Voluma works best.Kind Regards Dr Dinesh Maini Zenith Cosmetic Clinics
