Bad anchor scar camouflage with tattoo. What should I do? (Photo)

I got tattooed to cover scars after my breast lift around the areolae. She also tattooed the anchor scars but several shades darker than my skin tone! The scars went from white to brown. So depressed!!! Now she's saying she can lighten it with lighter ink. Should I believe her and go back or should I run to the dermatologist for laser removal instead? Will laser turn it black?? I went to another tattoo artist a year ago who told me the color would turn black if I tried to laser it. help!?
