You really need to see a doctor for this. People with darker skin have a higher risk of hypopigmentation.

I've seen videos of this done and I do believe it can work well in the right skin types. Sometimes I even think this is better than lasers or microneedling. But again, the risks...

I saw the videos in the past and had it done with one Dr.
Zero results. The floor of the scar stays the same. In the list of useless procedures. The edges of the scar have to be addressed precisely not rubbinghere and there.
