I'm very interested in acne scars.

How do you manage acne scars? My child had a lot of acne at home, and he still has acne scars.

I thought it was okay because I'm a man, but these days, appearances are important, too. So, I'd like to take better care of it. Does anyone know anything about acne scars? If you have any tips or tricks from your acne scar management, please share them here. I'd really appreciate it. I want to take good care of my acne.
