Because there are blemishes and marks mixed in.

My skin wasn't originally this bad. A while ago, painful, hard, pustular pimples started popping up one by one around my chin and cheeks, and now they have spread to my forehead and between my eyebrows. Even though I know I shouldn't squeeze them, they kept bothering me, so I ended up touching them. They wouldn't pop, and now dark, red acne marks (scars) have formed right in their place. With breakouts and marks all over my face, my skin looks so messy, and I feel like I'm going to develop social anxiety.

I've tried applying cica cream and tea tree oil that are said to be good for acne, and I've even used patches, but I can't keep up with the rate at which new ones are breaking out.

If I have both acne and acne scars like me, which treatment would be best to receive first? Should I get scaling along with extractions and anti-inflammatory injections? Also, if there is anyone who suffered from adult acne and achieved flawless skin through dermatological treatment, has anyone seen good results?
