Ghosting concerns after tattoo removal: are there creams/oils that can help restore the color back to treated area? (photo)

I have been receiving laser tattoo removal treatments for over a year now, and the ink is fading and clearing up but I’m left with a ghosting effect. I still have more treatments to go, and was wondering is there a certain cream or oil that can help restore the color back into the treated area once my treatments are completely over with? The laser that’s being used for my treatments is the Astanza Trinity Yag laser. (Q Switch).
