How can I manage acne scars?

These days, every time I wake up and look in the mirror, I'm shocked by how different my skin looks. My skin used to recover quickly after a good night's sleep, but now it feels dull and lifeless. In particular, the marks I've been carelessly touching up have now become darker, difficult to conceal with makeup. That's why I've decided to seriously focus on acne scar management. I've been using my busy schedule as an excuse to just do a cursory skincare routine, but I feel like I can't put it off any longer. I've been researching home care devices and diligently applying regenerative creams, but I can't expect dramatic changes. People around me advise that professional acne scar management is much more effective. How do you manage yours? I hope my skin responds honestly to the time and effort I put in. Do you have any tips for acne scar management that have proven effective during times like mine when my concerns are deepening? I'd really appreciate it if you could share any valuable insights, even if they're just a small piece of information, that could help alleviate my skin concerns.
