Based on your pictures and description, you are not likely to see optimal results with CoolSculpting (you will see some) and would probably most benefit from liposuction. Tummy tuck, in our opinion, would a second option to reduce your abdominal fat although you would get a scar. Alternatively, you can do a combination of any of the above modalities. Ex: CoolSculpt the flanks/lipo abdomen; lipo flanks/tummy tuck abdomen, etc. We recommend a consultation with a board certified plastic surgeon who can physically assess your skin elasticity, fat content, etc to make the most appropriate recommendation.
It is difficult to assess your needs without a picture and an inperson assessment would be ideal, but generally neuromodulators are not used to correct areas that have had HA filler. Neurotoxin can be used in the upper lip to reduce "gum showing" by paralyzing the orbicularis oris but this likely is not what you need/want based on your description. We recommend returning to your provider to discuss options or consult a board certified plastic surgeon.
The most noninvasive way to correct this issue would be with HA filler, which can be placed at various strategic spots in the nose to reduce the broad appearance. Placement over the bridge can provide height to a broad nasal bridge. Likewise, filler can be carried down along the nose to reduce humps, asymmetry, and bulbous nasal tips. Alternatively, a rhinoplasty with or without nasal implant is an option. We recommend a consultation with a board certified plastic surgeon to assess your options.
It is not uncommon for there to be swelling in the lips after injections for various reasons-inflammation from needle injections, volume increase with HA filler, fluid drawn in from HA filler, bleeding, etc. This can lead to asymmetry in the lips, which obviously is concerning. However, this will generally resolve with time over the next 1-3 weeks. We recommend waiting a little more time before returning to your provider to address any asymmetry that may need correction.
