The PC4Men Nighttime Repair is actually identical to our RESIST Barrier Repair Moisturizer with Retinol but packaged as part of the PC4Men line. We knew this hydrating formula would be a hit in both collections because of its weightless quality and positive effects on all skin types. Like the Barrier Repair Moisturizer, PC4Men Nighttime Repair also delivers several proven anti-aging ingredients (including retinol) for younger, healthier, stronger skin.
