"The Inkey List is a new addition to Sephora, and at a price point of $5-$25, it's hard not to buy everything in the line. I picked up the Retinol Serum ($10) last month and I'm impressed with the results. It includes a 1 percent stabilized retinol and .05% granactive retinoid, so it's strong but not harsh, and the squalane helps with any dryness you might typically incur from a retinol. (Granactive retinoids deliver the same benefits of retinoids and retinols, but with less potential for irritation.) My skin over the past few week has looked smoother, and my pores less noticeable. And since it's only $9, you have nothing to lose, really. (Except, like, two cups of coffee.)" — Kirbie Johnson, senior reporter and host
