Lipolab- chin/jaw area

I used lipolab in this area to fairly good results and I needed a new dose as I noticed a tiny bit of a second chin developing. However, I've noticed that after injecting,my double chin is even more noticeabl⁵-—..even my mom commented , and pointed out I've never even had a noticeable double chin😅. I'm hopeful that this is just swelling, especially as I can feel a little bit of a hardened lump in a my throat praying it goes down @and that it will go down in a couple weeks. I've been have been treating with some ice. But I'm just wondering if anyone else has had the same experience? Thanks!
