Best laser to remove facial skin stain left by bad jewelry? (Photo)

37, F, Fair skin, 5’5, 118lb. I took my nose ring out about 3 yrs ago & found the nickel had stained my skin. Unrelated - I got picogenesis treatment last fall for light forehead sun damage (NOT for the nose stain, but hoping it’d help both) but it had 0 effect on the stain. She suggested a “tattoo” removal treatment might work better on foreign pigment. Trying to decide which laser - enlighten, picosure, cutuera, picogeneis at higher setting, or other? Any success removing similar stains?
