Melanin
I'm darker skinned, neutral, but oily skin. At first I hated it for the white cast but hear me out. I tried something different. First I put on my moisturizer I know that doesn't make sense then I put on the primer of course white cast so I used my concealer and buffed it out with a Kashi flat brush then I did the rest of my make up. It came out flawless with no white cast. I hope this helps.
