I contacted the superhelpful CandyLipz people and asked them how to avoid bruising. They responded almost immediately. "Oh . . . you're going to get the cupping marks. ☺ Use it at maximum suction so you get the marks out of the way. You may get very dark cupping marks. Get a good concealer! We all went through this, but afterward, we can enjoy using the lip pumps as much as we like, and the cupping marks do not come back. We all have huge pouty lips like Jenner." It was then that I started to really take this seriously and went HAM on my poor lips. They recommended using it for six-minute intervals, but I chose four instead — I mean, look at these results! It only got scarier (and more impressive) from here.
