Obagi Medical Nu-Cil Eyebrow Boosting Serum 0.17 oz — Biotin & Hyaluronic Acid for Fuller Brows

Obagi Medical Nu-Cil Eyebrow Boosting Serum is a nourishing brow treatment formulated with Biotin, Sodium Hyaluronate, Panthenol and a lipid complex to visually enhance thinning, patchy, or over-tweezed eyebrows.

Designed for targeted eyebrow care, this concentrated 0.17 oz formula uses NouriPlex Technology to support the look of fuller, denser brows. It’s dermatologist-tested and physician-endorsed, and was evaluated in consumer studies that measured visible improvement in brow density, fill, and overall healthy appearance across an eight- to twelve-week period. The lightweight serum applies precisely to brow hair and skin to condition, add moisture, and improve the visual fullness of brows without heavy residue.

How quickly will I notice my brows look fuller?

Visible changes can appear within weeks when the serum is used consistently. Consumer study results showed measurable improvements in density and fill by eight weeks, with more participants noting enhanced overall appearance by twelve weeks.

• Use daily as directed for best outcomes
• Expect early visual changes around 6–8 weeks
• More pronounced results typically by 12 weeks

What key ingredients make this effective for eyebrow appearance?

The formula combines four targeted actives in NouriPlex Technology to condition hair and support a healthier-looking brow line. Each ingredient contributes specific benefits to hair appearance and skin hydration.

• Biotin — supports the look of stronger, fuller brow hairs
• Sodium hyaluronate — hydrates skin and brow hair to reduce dryness
• Panthenol — adds smoothness and shine to brow fibers
• Lipid compound — helps condition and improve texture

How do I apply Nu-Cil for best results?

Application is simple and targeted: apply a small amount to the brow area to coat hairs and skin where density is desired. Consistent, daily use increases the chance of visible improvement over the study period.

• Cleanse and dry the brow area before application
• Use the precision applicator to trace sparse areas once daily
• Avoid applying directly into the eye or on broken skin
