Obagi Nu-Derm Fx Blend (Arbutin)

A nighttime brightening cream that helps fade dark spots, sun spots, and uneven skin tone — without hydroquinone. The key ingredient, arbutin, is a gentle, plant-derived brightener that works over time to even out discoloration, while added vitamins C and E help support healthy, resilient-looking skin. The one thing to know: Blend Fx isn't used on its own. It's designed to be mixed with your retinoid (like Obagi Retinol 0.5) each night before applying — think of it as the product that helps your retinoid work more evenly across your skin while targeting tone. It's used once a day, in the evening only, as part of the Nu-Derm Fx routine.
