Colleen Rothchild's Mandelic Acid Radiance Serum is a treatment that leaves your skin looking brighter and smoother over time. It’s gentle enough to use every day and acts as an exfoliator. It also helps photo-aging, gets rid of dead skin cells, and helps boost radiance! This is another pro-aging powerhouse I’ve been using for years. The website says to use this item at night but I also love using it in the morning. Right now, you can get all Colleen Rothschild products at an amazing discount.
