[Lifiting] Is there really no pain in the ball in mode?

Those who have experience with cheek fat in-mode, please take a look. I tried the double chin in-mode a few times before, but I didn't know if it was effective or not. I thought it would be effective if I did it on my cheeks, so I tried it today. But there wasn't so much pain today, so it's a long time ago. It was really painful when I had a double chin. ㅠ I used to bite my teeth hard, but this time it didn't hurt to the point where I wondered if it was loose... I have more bruises than when I had a double chin and it feels like my face has shrunk a bit, but since there's no pain, I feel like I didn't do it in mode.
