ACNE 😭

Hey girls! So i have a question. How do you guys get rid of acne? I popped this pimple right in the middle of my chin and it left a bad scratch looking thing after (sorry idk what these are called) and it wont go away! I dont want to peel off the scab on top but it looks so ugly :( I've already done it once and now its a dot 😒 i dont wear foundation a lot so I'm trying to see what can get rid of it. Any suggestions ??
