Obagi Nu-Cil Eyebrow Boosting Serum is a targeted brow-enhancing formula designed to promote fuller, thicker, and more defined-looking brows. Powered by Obagi’s NouriPlex™ technology, this serum nourishes the hair follicles to encourage visible growth while helping deepen brow color for a naturally bolder, more sculpted appearance. With consistent daily use, sparse areas appear filled in, brows look darker and more uniform, and overall density improves—ideal for anyone wanting stronger, healthier-looking brows without makeup or microblading.
