While it's long served as a hub for amazing beauty deals, Amazon has yet to offer any product exclusives of its own—until now. New skincare brand Oui Glo is the first to make Amazon its one and only retailer. The Rich Collagen Face Mask is the line's debut product—it promotes a plump and glowing complexion by eliminating dead skin cells and improving elasticity. You can snag a pack of 12 for $39 or sign up for a subscription on the Oui Glo site. It's gentle enough for everyday use, so we're stocking up.
