You sound just like one of my classmates ...-=//)
18 years old, is puberty coming to an end? ...
First of all, you'd better not buckle yourself. You also know that if you buckle it, it will "dent a hole" for a long time, and it will fall off by itself. Don't worry.
I think it's stuttering. Don't buckle it. Your hands may be unclean (sterile). What should I do if I later buckled and grew a new acne?
Is there a black scar? After the acne grows out, it is "concave", which means that it has hurt the dermis and it is difficult to get better. However, black acne scars can slowly fade away.
In the sunken place, you may go to beauty salons and cosmetic centers or something ... there are collagen injections and microdermabrasion ... and you can also go to the beauty center for a pulsed light shower and colorful skin rejuvenation. ...
But it costs money.
If you don't have money, do some basic skin care and sunscreen (don't let the scar deepen) and you will get better slowly.
This is of course the best result, although it is a bit slow.
And don't always eat and write exciting things, which will never get better.
If you are not a acne scar, but an inflammatory acne, go to the hospital! When I was a child, I went straight to the hospital once when I was much older.
Just take medicine and apply it ~ ~ simple thing.
Another thing to emphasize is: pay attention to your air conditioning fan and pets ... and so on. Is it dirty? Always pay attention to cleaning these (I have a deep understanding ...)
As for the product, it is not recommended here. If you want to ask, I can leave a message, and basically I will answer you in 1 day.

But if the advertisement is as obvious as the fifth floor, forget it.
