I'm in 20's. I have horizontal rolls on my neck and I've had these ever since I was little? (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"

Neck rolls are typically from localized fat collection in your neck. The reasons for this are multifactorial - for example "runs in the family", related to your weight, hormonal, congenital,etc. Liposuction using fine cannulas are very helpful for this. If loose skin is an issue then some non invasive treatments like Ultherapy, Thermage, Thermi-RF, or the Sciton Laser BBL SkinTyte are good options as well. The result is significant improvement for most cases.

Although "getting rid of them" is probably not possible, these rolls are partially due to fat excess underneath the skin. This fat can be reduced using liposuction.

I don't usually use liposuction for the neck, because the fat may be in different levels. But it looks like the fat is superficial. Careful liposuction with a small canula might be helpful. Consult an experienced Plastic Surgeon to see if this is an option.
