27, lost 100lbs - nasolabial folds, sunken cheeks and loose skin on neck. Are a face and neck lift appropriate for me? (Photos)

Based off your photos - you do see NSLF deepening as you lose more weight as well as neck skin laxity. The question is if you continue to lose more weight and get to your final goal weight - how much more laxity and deepening will occur. From these photos, you can try chin liposuction with some type of skin tightening protocol (J plasma, bodytite) and see if your neck heals enough skin contraction to save the neck lift procedure for the future (40-50 yo +). Fat grafting to your midface can potentially help restore some volume there as well versus a facelift just yet. First get down to your goal weight and stay stable there, then seek out a few different opinions about facial volume restore before making any final decisions.

Based on these photos it looks like anterior neck lift with incision placed underneath the chin would be right procedure for your problem. This will reshape the anterior neck, improve the jawline and create nice neck-jaw angle. Possibly small chin implant. Good luck.
