Dr. Y Secrets Star-Powered PM Serum

"I'm a huge fan of Dr. Y's new line of products, Dr. Y Secret but my favorite by far is the Star Powered PM Serum. It contains retinol to stimulate collagen and leaves my skin moisturized and tightened by the morning. I recommend the line to everyone!" -Selene Milano, Senior Beauty Editor
