Please tell me how to manage pustular acne.

I've had oily and acne-prone skin since I was little... I always squeezed my pimples, especially the pustular ones. Those too ㅜㅠ Pustular acne fills up with pus and leaves a lot of scars when you squeeze it.. That was really stressful, so I was told to be careful about what I ate and even cut out wheat, but it didn't work. It would have been better if it was whiteheads ㅠㅠㅠ Is there anyone who has suffered from pustular acne..? Let's share some management tips.

Let's escape!!!!
