Do I need a neck lift to tighten and lift my turkey neck? (photo)

I don't even know what a one stitch facelift is but it sounds more an inadequate. It definitely looks like you'd need a real lift that addresses the platysma. Whatever a surgeon calls as a "mini lift" is just a marketing term - you'd want to ask specifically that the platysma is lifted.

Just based on your photo, I would say that you appear to be a good candidate for a facelift. This procedure tightens the neck and lower face. Your photo shows skin laxity in the neck as well as along the jawline. A facelift would improve both these areas.

Getting the lower jawline/neck smooth and tight is so easy with the advance Mini Lift which is done under local and with quick dramatic results. The 1 stitch lift is usually worthless.
