I have a very flat face, but it was stressful because it was turned off because I didn't have a front cheekbone.
I put 1cc of both sides together 6 months ago at Gangnam Station, and I am very satisfied.
But compared to other fillers, the thing to be careful about is that when you ask to see how this is, you can't touch it directly, so you don't know if the same amount has been put in both sides. When I got home and touched it, the right side retracted more.
