32 years old - What options are there to treat deep horizontal lines and skin laxity on my neck? (Photos)

Thank you for your question and for providing photos. You may benefit from RF microneedling to diminish the appearance of the horizontal lines you’re referring to. This treatment option uses radiofrequency technology to create micro-injuries in the skin while heating the underlying tissue, encouraging the body’s natural collagen and elastin production. RF microneedling makes the skin appear tighter and smoother, with results lasting up to five years or more.
Another option for you might be Botox injections, which target the platysma muscle in the neck. By reducing the activity of this muscle, we can often smooth away horizontal banding. I recommend scheduling an in-person consultation with an experienced, board-certified facial plastic surgeon. They will be able to assess your concern and suggest the best treatment option for you.

"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"

A full set of facial and neck photographs are required to make a determination about how best to proceed. The photos presented are inadequate. The horizontal lines on your neck are called "flexion creases" and there is no improvement for them. It's also important to remember that liposuction can only remove fat deposits above the platysma muscle, while a surgical neck lift is required to remove the fat deposits below the platysma muscle which also includes a platysma plasty to significantly improve the jawline.
