Deep nasolabial folds and platysma muscles - can this be fixed with some kind of mid face lift? (Photo)

Thank you for your question and for providing photos. Since you aren’t interested in Botox or fillers, you may want to consider RF microneedling treatments to increase collagen production and restore the skin’s elasticity.
RF microneedling creates micro-injuries in the dermal tissue and heats the lower area, encouraging the body to produce more collagen. The results of this treatment option can last for up to five years or more. I recommend scheduling an in-person consultation with an experienced, board-certified facial plastic surgeon who can assess your concerns and determine the best approach.

nasolabial folds and neck bands are very common complaints tat facelift surgeons see all of the time. The bands you see in the neck are from the edges of the platysma muscle. These need to be either sewn together in the front, pulled from the sides or both. Botox might help a little as a non-surgical option. Your nasolabial folds might need surgery, either a facelift, less likely a midface lift, or both. You really need a exam to figure out how your "face" moves. good luck.
