How to treat vertical neck bands?

"Injecting soft fillers like Belotero in this area can reduce lines, wrinkles and folds as well as improve skin texture with long-term collagen production. Fillers are being used more frequently to contour and lift rather than solely line fill. Of course, fillers are best used in combination with lasers and microneedling​ with PRP to get the optimal outcome.

I suggest getting a formal evaluation with a cosmetic dermatologist to create an individualized treatment plan that works for you. Best, Dr. Emer"

The neck can have vertical wrinkles and rings from an early age (genetics play a key role) as well as from sun damage and aging in almost everyone. They can be super annoying and are hard to get rid of.
Surgically removing them is the best way to get rid of them but this can leave a lot of scars in very visible areas which most people don’t want.
These rings are usually at the skin level. There are several nonsurgical and surgical options to consider. Some can be done at the same time. Surgery combined with injections and laser treatments before or after surgery is usually the biggest difference.  For people not interested in surgery, the hyaluronic acid injections and laser treatments are the most reasonable options, maybe combined with a chemical peel.
These procedures can be done safely in the office and the results are often very satisfying. An in-office private consultation and examination with a board-certified plastic surgeon would be the best way to fully  address your specific concerns and determine the right treatment plan.

Thank you for your question.  Without  pictures si very difficult to know for a fact what are those  bands but in most of the occasions those bands are created by the contraction of the platysma muscle.  There are several ways to treated but radiofrequency will not help and the most effective way is surgery
