31 Yr Old with genetic horizontal neck bands and loose skin. Is there anything I can do about it? (Photo)

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. 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.

Horizontal linnes on the neck are "wrinkles" that are either genetically predisposed or developed with aging. As wrinkles in the face, they could be improved with soft tissue fillers like juvererm, restylane or belotero.Excess of fat in the neck could be improved with liposuction in patient candidates. 

Hello.  I think you're a bit young for surgery at this time.  I recommend trying nonsurgical treatments first.  There are medical grade skin products that can tighten skin (but you must be aware the results won't be dramatic), but with regular use they may help improve the overall appearance.  CO2 laser at very conservative settings may also be an option.  Make sure you see a board certified surgeon or dermatologist to discuss these ideas.  Take care.
