What's good for clearing old acne pigmentation?

I had a blemish on my face a while ago that I accidentally touched, and now I have acne scars that haven't gone away for quite some time. I thought they would fade naturally over time, but they seem to be more prominent, so I have a hard time covering them up every time I apply makeup.

Rather than trying at-home whitening treatments, receiving professional acne pigmentation laser treatment at a hospital is the fastest and most reliable option, right? If anyone has experienced a brighter skin tone after receiving acne pigmentation treatment at Maypure, please share which treatment was best for you. I desperately want to get back to my clear skin!
