Neck cords and loose skin: dermatologist suggested I try RF Sublative to tighten my neck and then try Botox. (Photo)

Hello and thank you for your question. Based on your photograph, you are a better candidate for a mini facelift with a neck lift.  If good technique is used,
this can be done with minimal scarring and can result in a natural look, not
over-done look, with rejuvenation of your face.  Make sure you specifically look
at before and after pictures of real patients who have had this surgery
performed by your surgeon and evaluate their results. The most important aspect
is to find a surgeon you are comfortable with. I recommend that you seek
consultation with a qualified board-certified plastic surgeon who can evaluate
you in person.
Best wishes and good luck.

Some people require surgery to get the most improvement. There are non invasive options for improvement to the neck, which include:
botox, dysport or xeomin and/or fillers to help platysmal bandsthermage radiofrequencyultherapy high intensity ultrasoundPDO nova threads or instalift for liftingsculptra injections for collagen productionbtl exilis ultra, venus legacy, and thermi250 for constant collagen stimulationJ plasma or thermiRF internal tighteningI recommend getting a formal evaluation with an expert. Best, Dr. Emer

From a limited posted photo - it appears that you are a candidate for facelift/ neck lift.In the right hands you can certainly expect a very pleasing and dramatic result with this procedure.I would save the money and apply it toward this surgery.

Botox can be very beneficial if your neck cords are tight and standout especially when you grind your back teeth. If they are flaccid and hang down, relaxing them more has no benefit. Your dermatologist or a plastic surgeon can help you identify your situation. EXTERNAL  RF requires multiple treatments and the results are usually not dramatic. Risk of burns are much less than internal RF. 

Elena. A little Botox placed in the cords of your platysma muscle may soften your neck a bit but it will not affect the redundant skin. Also radiofrequency (RF) treatment has not been proven to cause significant skin tightening and it certainly will not tighten it in time for the wedding. Enjoy the wedding and if your neck still bothers you, consider a full facelift after the wedding.  Not enough time to recover before.  Be certain to consult with a board-certified plastic surgeon. Good luck.

Your picture shows laxity of skin under your chin, neck and jowls. This is causing the prominent nasolabial folds and the marionette lines. Your ultimate, treatment is a face and neck lift. I do this under local anesthesia with moderate sedation and you need about  two weeks recovery. I don’t see your platiysma muscle bands on the resting picture, but those band are probably active bands that appear when you are talking and with facial expressions. If you can’t afford the operation now,  there are two things that can give you some improvement. Botox or Dysport can reduce the appearance of the active bands by relaxing the platysma muscles, but will not change the skin laxity that is present now. Fillers like Restylane Lyft and Radiesse can improve the nasolabial folds and the marionette lines for now. RFs don’t work and will not make a difference, so don’t waist your money on that. Filler treatment and Botox have to be repeated and the cost can be significant over time. It will be more economical to save your money for an operation that will give you long term results. It’s always good to see a doctor who will put your interest first and can offer you all the options with the pros and cons.

Neck chords, also known as platysma banda and loose skin can not be corrected by any non-invasive procedure. Botox will not significantly improve platysma bands. You will be spending money for almost no results. Surgery is the only way to correct platysma bands and loose neck skin

Hello Elenak14:
I have read your question and all the answers below carefully. You must be feeling somewhat confused just now. Although seemingly contradictory, I believe there is truth in all of the answers below, which arise from the authors’ own experiences. 
Platysmal bands can be relaxed using Botox, which results in a smoother neck with skin that is more tucked up against the underlying muscles. It is impossible to tell whether you have platysmal bands from your photograph, but if you want to try something at home, you can jutt your lower teeth out in front of your upper teeth and then say “Eeeeeee.”  If your muscles pop out and feel firm, you have platysmal bands that should respond to Botox. If not, and they stay soft, you would normally want to consider one of several options. 
Those options include radio frequency or high frequency focused ultrasound energy applied to the surface of the skin, such as with Pellevé, ThermiSmooth, or Ultherapy, or the application of radio frequency energy under the surface of the skin, such as with a ThermiRF procedure called ThermiTight. In have seen impressive responses with Pellevé, ThermiSmooth and Ultherapy, although the full results are not apparent for 6 months to one year after treatment. Sublative RF delivers RF energy to the surface of the skin, and will not penetrate deeply enough to achieve the tightening you are looking for. In the ThermiTight procedure, which takes one to two hours on the neck, a blunt cannula is placed through a tiny opening in the skin and radio frequency energy is delivered under the skin and near the fascia while carefully monitoring the temperature of the skin’s surface and under the skin, using two different monitoring technologies. In a facelift, the fascia is drawn to the sides of the neck, whereas in ThermiTight, the fascia is tightened in all directions via a process called bulk heating, resulting in a very natural-looking tightening of the neck, and also a smoothing of the surface wrinkles. The results can begin to become apparent in two weeks and are very significant at three months, with some continued improvement over the following 6 to 12 months or even more. 
Considering your time frame, I do think you might consider Botox if you have bands, and ThermiTight if you have looseness. The looseness seen in your photo is only mild to moderate, so you may never need a neck lift, but there is no reason you would not be able to have a facelift later in life if you notice additional loosening due to continued aging (or another ThermiTight procedure). You also do not have time to recover from a necklift before your very important event, and your downtime as well as your expense will be much less significant than having a neck lift. As technologies advance, the trend in aesthetic medicine is toward noninvasive and miniinvasive procedures, and with good reason. But there will always be problems that only a scalpel can correct.
I do hope you can find some clarity about all of the options.   Enjoy the wedding!

Over the last few years there has been a glut of RF devices for skin tightening. Many of these devices are ineffective. The only technology that we have found to be significantly effective has been the use of Renuvion, me also called j-plasma. We have been able to tighten the next in individuals who are close to 80 years of age without the need for any surgical intervention. Good luck from New York City
