Why do I have rolls of skin on my neck when I've never been overweight? (photo)

"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"

You need an in-person evaluation with a well-respected facial plastic surgeon who can assess your case and give you options that include customized treatment plans.

Thank you for your question.  As others have stated neck rolls are usually hereditary.  Neck rolls may be improved with liposuction at often and neck lift is also required.
