Is there a way to quickly get rid of acne red marks?

I'm concerned about the red acne scars on my face. They tend to last a long time, so I'm curious about products or treatments that can help improve pigmentation. Could you share your experiences with acne scar treatments at the hospital or at home (skincare, laser, peeling, etc.)? Also, if you have any tips for improving acne scars, please let me know.
