What procedure will tighten my neck and jowls? Platysmaplasty / Lipo / Necklift / SMAS Facelift. I'm getting confused (Photo)

Thank you for your question and pictures.  The necklift needs to be performed with the facelift.  The scars are the same, and the result will overall be better and not disjointed.  This will removed the little jowls you have, making a contoured jawline and removing any skin laxity.  The neck from the pictures I would suggested a little bit of liposuction under the chin and then a neck lift, to create a nice L shaped neck.  These can be performed under local anaesthetic, giving a youthful and fresh appearance.  Patients normal prefer local anaesthetic because the downtime is significantly reduced.  Patients normally returning to work after 7-10 days (if you have liposuction 10 days maybe needed as you tend to get a little more bruising).What are the benefits of a local anaesthetic facelift?
Minimally invasive as it is a short scar faceliftThere is minimal bruising and swelling, especially when compared to traditional faceliftsAs the procedure is performed under local anaesthetic, you can go straight home following the procedureFull recovery in a matter of days rather than monthsSignificantly less risk than Facelifts performed under general anaestheticFresh, youthful and long lasting resultsStandard aftercare for a facelift includes, sleeping upright for the first week to minimise a collection of blood forming, showering and washing your hair every day post surgery and drying using a hairdryer on a cool settings, not allowing pets to sleep in your room or on your bed. Painkillers as prescribed by the surgeon, antibiotics if needed and prescribed by your surgeon. 
Please make sure you find a reputable and qualified plastic surgeon who can assess you properly to give you a realistic idea of what outcome you can achieve.  All The Best 

Thanks for sharing. In general, current neck and lower face rejuvenation treatments include
Surgical Neck lift* with a Lower Facelift would be the gold standard and gets the best overall results in the jowls and neck and indicated in middle age and older patientsSurgical Neck lift* which involves lifting and removing loose skin from behind the ears would be the next best procedureNeck Liposuction and/or Laser Lipolysis if only fat removal is required, typically in a younger patient. (A platysmaplasty can be added for further muscle tightening if needed)Ultherapy is an FDA approved non invasive tightening using ultrasound technologyKybella is a new FDA approved series of injections that melts fat under the chinCool Sculpting is FDA approved energy device to removed fat from under the chin as well. Botox to the platysma bands to decrease their activity and show*It is important the a Neck lift involves some liposuction and importantly a platysmaplasty which is a procedure that tightens the underlying loose neck muscles.  From your photos option 1 is the proper choice. Patients do not like to hear they need all this work but for an experienced surgeon this is straightforward and you will have the highest satisfaction rate.  Anything less is less results and will be less satisfaction.  Hope this helps to read this and make an informed choice. Consult with several board certified faciall platic / plastic surgeons experienced in face and neck rejuvenation to discuss your options
