Thank you for your question. I suggest that you consult with your board certified facial plastic surgeon to discuss your recommended recovery process. At a few weeks post-op, you are still very early in your healing process.
Best wishes,
After a corset platysmaplasty, skin is pulled toward the middle. That pull must be compensated by doing a lifting procedure laterally. Although you may not need a facelift, neck lift incisions and pull laterally would also ideally be needed.
