Q: What can I do to make my jaw line slimmer or more tight? Is liposuction and/or a lower facelift an option? (photos)
It is best to be seen by a surgeon for complete evaluation, but neck liposuction, buccal fat excision and jawline fillers may all be options. Neck liposuction removes the fat just below the skin under the chin and along the jawline but not up on the cheek. You seem to have some fullness in the area of the buccal fat (on the cheek). This can be treated with an incision inside the mouth and removal of that fat. There is no way to know based on your photos if these are the best options, but are worth discussing with a board certified facial plastic surgeon.
Q: Do I need a neck lift or lower facelift? Or both? (photos)
Weight gain can cause some laxity of the skin that may remain even after your 100lb weight loss. A combined lower face and neck lift will lift up the structures that have fallen down with gravity and remove the excess skin. Therefore it is best to combine the two. Just remember that even with this complete lift, there may be some lax skin, but your overall result should be excellent.
Q: 4 months post-op. What do you think of my neck lift and droopy eye? Does it look right?
All looks very good. Normal for the neck muscles to bulge a little for the first year due to swelling. With the tincture of time, all the swelling will likely resolve. Very nice result in my opinion!
Q: Why am I starting to see Voluma lip filler bumps after my lips were reduced and refilled?
Voluma is not an ideal filler for the lips. The characteristics of Voluma as a filler are best used for deep injections. The complete opposite is generally needed for the lips. Some people may do well with Voluma to the lips, but if you have an issue with it, it is best to go to a different, less thick filler.
Q: Would you recommend chin lipo or neck lipo? (photo)
You seem to be an excellent candidate for full neck liposuction that will help sharpen the angle as well help define your jaw out to the sides as well. The fat liposuctioned from the neck will not be enough for the BBL or contribute to it significantly. It is important for your surgeon to do an exam and make sure you don't have any loose muscle or skin that I can not see on your photo.
