Profractional, Acne Scars and Vitiligo

Is profractional laser treatment recommended for someone with acne scars AND Vitiligo? My cosm surgeon said I will need min 3 treatments & possibly fillers for some of the deeper scars. Does that sound right? Background I am E.Indian of SkinType4. See pic for acne scars. I have Vitiligo, tho no vit scar noticed on injury. My surgeon doesnt think profractional will cause any Vit issues. But I have asked him to do a test patch first and wait for 6 wks before we do the full face. Good idea??
