Obagi Medical Nu-Cil Eyelash Enhancing Serum Pack of 2 — 0.1 oz Tubes, NouriPlex for Fuller, Hydrated Lashes

Obagi Nu-Cil is a clinician-formulated eyelash enhancing serum that targets the look of thinning, sparse lashes to help them appear thicker and more densely packed.

Designed by Obagi Medical, Nu-Cil is a daily eyelash serum created to visibly improve lash fullness using a patented ingredient blend. The formula combines nourishment and hydration agents with performance nutrients to support the appearance of healthier-looking lashes. This twin-pack contains two 0.1 oz tubes so you can maintain a consistent routine or keep a spare on hand.

How does Nu-Cil improve the appearance of thinning lashes?

Nu-Cil delivers a concentrated mix of proven cosmetic actives that work together to strengthen and hydrate lash fibers, promoting the look of increased thickness and density over time. Results reported in clinical testing indicate many users noticed visible improvements after continued nightly use.

• Contains NouriPlex Technology: a blend of biotin, lipid compound, sodium hyaluronate and panthenol
• Hydrates lash fibers to reduce brittle or dry appearance
• Applied along the lash line once daily with the precision applicator

What ingredients are in the serum and why do they matter?

The serum’s formula focuses on nutrient and moisture support rather than pharmacological action. Key components were selected for their cosmetic benefits—enhancing the look and feel of lashes by providing structural and humectant support.

• Biotin: a nutrient that helps improve surface texture and appearance
• Sodium hyaluronate: attracts and retains moisture for a plumper look
• Panthenol and lipid compound: help condition and protect lash fibers

How should I use Obagi Nu-Cil for best results?

Apply Nu-Cil once daily, preferably at night, to clean, dry skin along the upper eyelash line using the applicator. Consistency matters—clinical testing evaluated results over weeks, so regular nightly use is recommended for the appearance of noticeable changes.

• Cleanse the eye area and remove makeup before application
• Use the fine applicator to apply a thin line to the upper lash base
• Allow the serum to fully dry before applying other products or eyelash cosmetics

Is Nu-Cil safe and tested with eye care professionals?

The formula has been dermatologist- and ophthalmologist-tested and is part of Obagi’s physician-endorsed portfolio. Clinical studies reported high rates of visible improvement from participants when used as directed over a testing period.

• Tested by dermatologists and ophthalmologists for cosmetic use
• Clinical data on file showing participant-reported improvements
