My neck platysma muscle bands are very visible 7 weeks after necklift (photo)

The fact that you had suction the fat under your neck causes  that the muscle   to be more visible.  Some fat in the neck is important to maintain to cover the muscle.  Now the picture was taken with a contraction of the muscle I wander how it looks without the contraction because is important to recommend the procedure that will be more appropriate

A formal neck lift with plication of the neck bands together called a "corset plastysmaplasty" usually solves this issue.  It's definitely not a "mini lift" however minilifts alone usually get only subtle results.  Best Wishes!!

It appears that you have two very prominent platysma bands.  They are basically the medial bellies of the platysma muscle that have separated.  It also appears that you may be contracting the muscle which will make them more prominent.  Unfortunately, a mini facelift  procedure will not improve the platysma banding.  Your banding is significant enough that a formal platysmaplasty would need to be performed.  A lateral neck lift in conjunction with a submental incision may be required depending on the neck skin and platysma laxity.
