You should expect swelling after any fillers - and for you, it's only been one day. I recommend you keep your hands away from the area and do not massage. I've seen many people think they are helping by massaging and they move the filler around, and then it looks worse as the swelling resolves and the filler is left behind. Swelling happens. Keep your hands away from the area. And return to your injector in 10 days if everything doesn't look as you expected.
