I went to get lip fillers done before and was recommended to do so, so I only did it once, but of course, there was really no change with just one session... I saw reviews saying that one session made a lot of changes, so I hoped that there would be even a slight change, but there was nothing like that. If I had done it multiple times, I would have seen some effect, but I don't do it anymore... It's too expensiveㅜㅜ The director was very kind.
