I am worried about the pitted scars left after squeezing pimples when I was young.

I used to have a lot of acne when I was a student.

I didn't take care of my skin and kept picking at it, so I ended up with a lot of scars back then... I'm especially bothered by the indented area there ㅠㅠ It's not just a simple dot; there are deep marks. Is there any way to alleviate this with cosmetics? Please let me know if anyone knows how to reduce one acne mark and the slight indented scar on my forehead.
