What should I do to smooth out my horizontal neck lines? (Photo)

Yes, you can try a dermal filler like Juvederm or Restylane Silk to help improve the horizontal line in the neck.  If that is not enough, sometimes, a combination treatment maybe best combining Microneedling + PRP with a dermal filler.

Thank you for your question and photo. When injected directly into the neck bands, Botox targets the platysma muscle, reducing its activity to minimize the appearance of the horizontal lines. This treatment option can also prevent the banding from getting worse over time when an appropriate dosage and injection schedule are maintained.
I recommend scheduling an in-person consultation with an experienced, board-certified injector. They will be able to further assess your concerns and determine the best treatment option to help you achieve your aesthetic goals.

"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"

Hello,thank you for the photo and the question.YES. if you want to see immediate results then fillers can temporarily improve the neck horizontal lines. Depends on the filler it would last 6 -12 months.In addition, you could help by using skin tightening creams available. try more of medical skin care lines for better reliability.Hope the Best  --- Dr Ray

Thank you for your question. Botox can lessen the appearance and smooth out the wrinkles that you are concerned about. Another option is using a thin filler to smooth out these lines such as Belotero. Novathreads can also be used in these lines. I place PDO sutures which dissolve in these neck lines, and while these absorb, collagen will be stimulated. Hope this helps!
