HI! I had a neck/face/under eye lift surgery 9 months ago. It was amazing. After 4 months we noticed my neck was sagging on one side. after 6 months quite a bit and some on the other side. Now 9 months it has been suggested as a fix an in office procedure cut in the neck that would be quick and could fix it right up. Have you experienced success using this as a fix with this issue?
