Acne scar management for high school girls

I'm curious about acne scar management for high school girls.

I've had severe acne since middle school.

If the child sleeps well, the skin will get better.

He always says he has to go to the academy and do his homework ㅠㅠ He's a kid who can't sleep well, so his skin is red and irritated...

It's coming up and my pores are getting really big and my skin is a real mess so my acne scars seem to be getting worse.

I have no idea how to manage acne scars.

I went to the dermatologist before and they extracted it and put a pack on it, but that was the only time it happened.

And I don't have time to keep going to the dermatologist...

I'm curious about acne scar care that can be done at home for children like that.
