So I have scheduled my first subcision for this June, and I think I will try the suction method after reading some success stories about it. My question is how powerful should the suction be when you apply it to your face where subcision was done?

I bought these suction cups and it left a big red mark on my face for 2 days, and it was kind of embarrassing to go to work with a big circular red mark on my cheek. I heard that someone here used a vacuum cleaner to suction the face. How powerful should the suction be if you use a vacuum cleaner, I read that he used his hand to lessen the suctioning power.
