Selma Blair may be best known for starring in classics like Cruel Intentions and Legally Blonde, but she's recently added another impressive gig to her résumé. The actress just teamed up with the doctor-developed Australian cosmeceutical skincare brand ESK to launch their latest product, Ultimate A Gold. The night cream is infused with clinically-backed agents like skin-strengthening niacinamide and retinal, which stimulates collagen without causing irritation. But this collaboration goes beyond a typical celebrity beauty deal.
