My first patient yesterday had exactly the same issue and was treated with a robust HA lifting filler injected at the angle of the mouth, which both straightened the angles of the mouth, but eliminated the marionette jowls. The procedure takes between five to ten minutes, the results immediate, and there is little to no significant post-treatment downtime. Unlike Sculptra, the treatment is typically less expensive, the results of treatment are immediate, three treatment sessions are not required, and should there be any unwanted or untoward reactions, HA fillers can be dissolved quite readily with hyaluronidase. You would be wise to make sure to consult with an experienced, board certified cosmetic dermatologist filler expert and best of luck.
