Crepey, Saggy Neck at 39, What Are My Options?

Thank you for your question and photos. Based on your photos provided, you do have excess skin and this can be caused by weight gain/and or loss as well as genetics and sun damage. You are an ideal candidate for a neck lift. I would advise you to schedule a consultation with a board certified plastic surgeon for a detailed examination to discuss all possible treatment options and what your expectations are.

A surgical neck lift has the ability to rearrange and adjust amounts of tissue, thus they can remove excess skin and tighten muscle bands. Nonsurgical skin tightening treatments can improve the quality of the tissue left behind,  which can have an immediate affect and help age proof your neck and jawline moving forward. 
Overall, tightening can have improvement to the jowls and neck to some degree, but they do not truly alter the amount of position of those tissues.  When true tissue excess is present, whether that is skin, fat or muscle, surgery is needed. To ensure you are receiving the highest level of care, seek out a modernly trained, new-school dermatologic surgeon, oculoplastic surgeon, facial plastic surgeon or plastic surgeon who is board certified and fellowship trained in one of these “core four” cosmetic specialties. Membership in organizations like the American Academy of Facial Plastic and Reconstructive Surgery help to identify a highly trained surgeon.Cameron Chesnut #realself hall of fame Physician 

There are many options for improving the texture and skin laxity of the neck skin, with a number of skin-tightening lasers such as Thermage, SkinTyte and Ultraformer III that improve skin laxity with minimal or no down-time. These however need to be continued for ongoing improvement.The surface texture of the skin can be improved by laser resurfacing with the HALO and Medical grade Fraxel DUAL lasers the best for this, although there are other options such as needling.
For a more long-lasting result then a lower facelift and necklift is the best option to improve skin laxity, although these do not improve the actual skin texture, so other resurfacing treatments may be necessary.
