Can Restylane be used for lines in the neck?
Hmmmm – your question makes me wonder how much experience your doctor has with these products because, in general, most experienced injectors do not try to use hyaluronic acid fillers like Restylane or Juvederm in neck lines. At least not at full concentration. There is a method that some board certified dermatologists use that involves thinning Restylane or Juvederm a little with sterile saline (salt water) or lidocaine (a numbing agent) to allow it to flow better into smaller lines like neck ("necklace") lines or lines on the upper lip.
In Europe and other parts of the world there are many other choices of hyaluronic acid fillers and some of these are thinner. The choices are not always a good thing. Some of these other fillers are not of good quality and can and have caused allergic or other bad reactions. When this happens it is usually due to a higher protein load due a cheaper manufacturing process or chemical contaminants. More on problems with fillers and how to avoid them.
If you are in Europe, Asia, South America, etc – stick with Belotero (if you want small lines like the neck treated) made by Merck. It’s thinner than Restylane/Juvederm and of good quality. We will hopefully get this product in the U.S. soon. Allergan blocked it’s release in the U.S. in what seemed to me to be a frivolous lawsuit that was not in our (the consumer’s) interest.
Another strategy for these lines on the neck, is to use tiny drop of Botox along the "necklace" lines. This works quite well. Certain lasers work well too but this is a more complicated topic.
For your particular situation, I would recommend asking your doctor to remove it with hyaluronidase. Hope this helps, Dr. I
