What causes me to have a neck rolls? Can I do something about them with plastic surgery? (photos)

"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"

This banding is a result of genetics. I would prefer an in-person examination. I would like check your neck fat content and the skin elasticity. It seems you do not have an obvious skin laxity. You do not have platysma bands either. It seems the best way to begin with will be neck and submittal liposuction. But I would like offer a significant weight loss as a first step.
 

Such banding is a common result of genetics. The presence of banding down the front of the #neck, and, amount of excess skin and condition of your skin are among some factors which determine if you are a #candidate for #rejuvenating the neck. During an in-person examination, your chin will be evaluated along with the neck and jawline. A weak #chin implies a lack of chin support for the skin along the neck line. 
Per your photos,  great amount of laxity is not evident. Nor is vertical banding . So, you may benefit from #non-surgical treatments. #Liposuction may also be an #option. I suggest consulting with a board-certified plastic surgeon to learn about the #options and products available and as to which may be best for you.

It's best to lose the weight first before you consider any surgery. You may be able to see a difference in your neck, making surgery unnecessary. Aim for achieving a stable weight that puts you in a normal BMI range. You'll enjoy the health benefits of being at a better weight! It's very hard to say why you have neck folds, but it is often caused by genetics. 

Fat collection in your neck are multifactorial - for example "runs in the family", related to your weight, hormonal, 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. In your particular case it is most likely due to the fact that you are overweight and need to get to a normal BMI. If there are still residual "fat rings" then the above could be considered.

Thank you for your pictures and questions. Some people are genetically prone to having a double chin, and you might be one of them. However, if you were to lose weight, you would likely see a great improvement in this area, since the adipose tissue of your neck will shrink, thereby improving the look of your neck. If weight loss does not improve the situation to your liking, you might want to consider liposuction of the neck to remove the excess fat, and to improve the contour of the neck and jawline. Liposuction is performed with tiny cannulas that are inserted through small incisions behind your ears in a spot that nobody sees. The small cannulas remove fat and help to sculpt and define your jawline with precision. I recommend consulting with a board-certified plastic surgeon in person to discuss your concerns to determine if neck liposuction is appropriate for you. The price can vary greatly, depending on the instrumentation used, the skill of the surgeon, and the quality of the facility.

Weight gain will present differently in different people. But for most people, the neck is the first place on the face to show excess weight. The good news is that any degree of weight loss will also show first in the neck.Your skin looks good so weight loss should improve those rolls that you do not like.Good luck!

It may be genetic and your current weight.  Some women gain weight in different places, you seem to in your neck area.  It may be possible to liposuction your neck area, at your age the skin may conform to the rest of the neck.  That with a healthy diet may be the result you are looking for.Good luck
