Full Arches, No Pencil Needed: The Brow Boost You’ve Been Waiting For
Sparse brows? Overplucked in the early 2000s? Or maybe your arches have just lost their fullness over time? We get it—and so does Nu-Cil Eyebrow Boosting Serum by Obagi. Designed to help you ditch the brow pencil and grow back your natural fullness, this powerhouse serum is changing the game (and your brow goals).
Obagi’s Nu-Cil Eyebrow Boosting Serum is formulated with Obagi’s proprietary NouriPlex™ Technology—a potent blend of biotin, panthenol, keratin, and proprietary growth-supporting ingredients—to target the growth cycle of your brow hair. Translation? Fuller, denser, more defined brows—naturally.
Unlike makeup or tinting, this serum works with your natural brow follicles to:
Enhance thickness and density
Support natural growth cycles
Improve resilience and texture
Fill in over-tweezed or thinning areas
All with no microblading or makeup tricks required.
Who It's For
✔️ Anyone with thin, patchy, or uneven brows
✔️ Clients recovering from years of over-tweezing
✔️ Those looking for a natural alternative to brow tattooing or microblading
✔️ Makeup minimalists who want to wake up with fuller brows
Whether your goal is bushy and bold or simply filled-in and defined, Nu-Cil can help get you there.
When to Expect Results
With consistent daily use (usually at night on clean, dry skin), most users start seeing visible improvement in as little as 8 weeks, with fuller results around 16 weeks.
Patience pays off—and so does daily commitment.
The CORE Aesthetic Take
We’ve seen clients go from barely-there brows to full, confident arches with this one simple step. It’s easy to use, doesn’t interfere with makeup or other skincare, and is ophthalmologist-tested for safety and tolerability. In short? It’s a brow revolution in a sleek little tube.
