Bye Bye Dark Spots from @IT Cosmetics review: This is a buildable-medium coverage concealer, and it has its own brush to blend in touches. The best part is that it's also a serum with 2% niacinamide, hyaluronic acid and caffeine. The shade I chose is Light Cool 20, but a shade higher would have worked too. Do you like this natural finish? #gifted #ugc
