@SaraGoodman I know HA needs and attracts water. I’m thinking it might have something to do with it. But my injector always massaged my lips afterwards. It hurt so much. He also left my lips super swollen and covered in bruises. Whereas I rarely give myself a bruise and my swelling is so minimal. I use the same brand of filler my injector did so it’s hard for me to compare. But mine gets hard for the first few days when I do it and I don’t recall them being so hard when he did them but I was also super swollen when he did it. I don’t massage my lips. I have used cheaper less known brands of fillers and my only real bug bare about them is they don’t last as long
