Can Crepey Neck Skin After Submental Lipo Be Fixed?

  I agree that a photo with your head turned sharply is not an ideal way for any of us to decide if there is skin laxity and excess. But it is likely that there is and that this would be improved with a well designed mini lift procedure.

A facelift can be preformed with a shorter incision in patients who have moderate skin excess. Depending on the surgeon, the two procedures can be considered variations of the same operation. The amount of skin excess that you have is moderate and can possibly be adressed with a short incision facelift. In this procedure, the SMAS and platysma muscles can be tightened, and excess skin can be removed around the ears and redraped to tighten your neck. The other non-surgical treatments you are considering may not be sufficient to correct the skin excess demonstrated in your picture. Good luck.

Your best option is probably the use of a mini lift as suggested. Your condition is due to loose skin. Unfortunately, at this time, there is no technology that can effectively, consistently and predictably tighten skin despite numerous claims. If we had such a device, it would obviate the need for tummy tucks, breast lifts, and face lfits.

Loose skin in neck really is best treated with a neck lift or mini-facelift.  The lasers to tighten the skin will give an incremental improvement.

The mini face lift does not address the neck at all. There are lasers and light treatments and thermage treatment that claim to tighten skin. None of these treatments really do any thing.
