Nars Pot Concealer does nothing to hide my dark acne marks. Any other recs?

As title says, any recs to cover my acne scars? I'm a person of colour and so my marks are dark, near black. Everyone says Nars Pot Concealer is great to spot conceal. So I bought it, used the Bobbi Brown Colour Corrector, applied that then the Nars over it. My marks still come through. I don't know what to do😭
