Obagi Medical Nu-Cil Eyelash & Eyebrow Serum Set — 2‑Piece NouriPlex Formula for Fuller, Thicker Lashes & Brows (Clinical Results)

Obagi Nu-Cil Eyelash Enhancing Serum & Eyebrow Boosting Serum Set is a two-piece treatment duo with Obagi's NouriPlex Technology designed to visibly enhance the appearance of lashes and brows in as little as eight weeks.

This paired set combines an eyelash-enhancing serum and an eyebrow-boosting serum formulated to support the look of thicker, fuller, and more defined eyelashes and eyebrows. Both serums use Obagi's NouriPlex Technology — a clinically tested blend of ingredients — to target the appearance of the lash and brow growth cycle, helping to build results over a 12-week regimen. The formulas are dermatologist tested and developed by Obagi Medical, a brand with decades of clinical skincare experience.

How quickly will I see differences in my lashes and brows?

Users in clinical testing reported visible improvement as early as eight weeks, with more pronounced results by twelve weeks when used consistently. Individual results vary based on starting condition and application routine.

• Noticeable change often begins around week 8 during regular nightly application.
• More substantial density and definition typically appear by week 12.
• Consistency—applying as directed each evening—supports ongoing improvement.

What ingredients are behind the NouriPlex Technology and how do they help?

NouriPlex Technology is Obagi's proprietary blend formulated to nourish the visible structure of lashes and brows. The mix focuses on ingredients shown to enhance the healthy-looking appearance of hair and the skin at the base of lashes and brows without harsh actives that can cause irritation when used correctly.

• Ingredient blend targets the anagen-like phase to support visible fullness.
• Formulated to condition and strengthen the appearance of hair shafts.
• Dermatologist tested to suit a range of skin types and eye sensitivities.

How do I apply each serum for safe, effective use?

Both serums are intended for external use along the lash line and brow line, applied with a thin brush or applicator for controlled coverage. Use a gentle, nightly routine and avoid getting product directly in the eye; if contact occurs rinse thoroughly with water.

• Cleanse and dry the eye and brow area before application.
• Apply a fine line of eyelash serum to the upper lash line once nightly.
• Brush eyebrow serum along sparse or thinning areas once nightly for even coverage.
• Allow product to dry before applying other skincare or makeup the next morning.

Are these serums suitable for sensitive skin and around the eye area?

The formulas are dermatologist tested and designed for use around the delicate eye area, but individual tolerance can vary. Start with a patch test and follow the instructions; discontinue if irritation develops and consult a physician if needed.

• Dermatologist tested and formulated to minimize irritation when used as directed.
• Recommended to patch-test if you have known sensitivities or react easily.
• If irritation occurs, stop use and seek professional advice.

Who is this for: The Obagi Nu-Cil set is suited for anyone seeking to enhance the look of naturally sparse, thinning, or over-plucked eyelashes and eyebrows without resorting to extensions or tinted cosmetics. It is appropriate for adults of varying skin types who want a targeted nightly treatment to build the appearance of fuller, more defined lashes and brows over weeks of consistent use. Professionals and at-home users appreciate Obagi Medical's clinical background and the product's compatibility with routine skincare regimens.
