Is It effective/safe to use a microroller on anchor lift scars? (photo)

I had a breast lift w/implants 8 months ago. There was a split in the junction under my right breast that caused a large scar to develop. My PS plans to remove it next month. I don't have any issues on my left breast other than a noticeably raised scar line, much bigger than the scar line on my right. I have used a .05 micro roller on the left breast scar with vitaminE oil a few times & I believe that has helped it go down. Can I continue doing this?
