This is a fun area to treat as it attempts to restore a more youthful appearance of the jawline. As we age, the jawbone thins out and elongates. Filler can restore the appearance of the thickness of the jawbone. It is considered a more advanced technique and definitely better with a cannula. It is also an area you don't want to overfill...a little bit can go a long way. You can always add more a couple of weeks later.
I'm sorry to hear you are unhappy with your results. It is impossible for me to compare the before photo with all the after photos. It is at a different distance with different lighting and unprepared skin. That said, your photos (which I understand you to say are 4 1/2 months out) show some pigmentation changes and skin texture irregularities. It would be highly unlikely for Halo to lead to the texture issues. It usually improves it. As for the pigmentation, it is rare that only one BBL treatment will resolve the pigmentation. As a matter of fact, BBL will sometimes cause the deeper pigmentation to arise from the deeper layers. A repeat BBL should help. The swelling around the mouth is most commonly seen with fillers. I see different volume to your lips, which makes me wonder if you have filler that might be contributing to the changes around the mouth. Either way, it would be important to follow up with the treating provider and address your concerns. They will also have photos of your face prior to any treatment. Best wishes!
I have seen this before. It is most likely from BBL. The area directly over the breastbone is at increased risk for thermal injury (just like the forehead). I am very hopeful it will heal...but may take about six months. If there is any residual discoloration after that time, then one can use some other treatments to reduce the discoloration. A very good chance it will go away entirely.
Coolsculpting involves permanent loss of fat cells, while Emsculpt builds muscle and reportedly causes fat loss. Emsculpt requires regular follow up treatments...it is not a permanent solution. There is alot more published research on Coolsculpting and it has been around alot longer. Also, realize that several competitors to Emsculpt will be coming out in the next year or so. The price is likely to drop when there is more competition.
The hardest part is waiting for two weeks to determine how they are going to look. The first few days are always the scariest. It is amazing how much they change after two weeks. It is why it is so important to schedule a two week visit no matter what. In looking at your baseline photo, I would not have done much of anything with your lower lip and added to the upper lip. Filler can always be added in a couple of weeks. It is much harder (but not impossible) to remove it.
