Obagi Nu-Cil Eyelash Enhancing Serum | Biotin Lash Serum for Thicker, More Defined Lashes

Lashes That Command Attention. Without a Single Coat of Mascara.

The Obagi Nu-Cil Eyelash Enhancing Serum is a clinically formulated lash treatment designed to visibly nourish, thicken, and define lashes from the root. Powered by proprietary NouriPlex Technology and enriched with Biotin, this precision serum delivers targeted conditioning directly to the lash line, supporting the appearance of fuller, more defined lashes over time. Developed by the trusted skincare authority Obagi, this is not a cosmetic fix. It is a long-term investment in the lashes you have always wanted. One application per day is all it takes to begin your transformation.

Why This Stands Out

• NouriPlex Technology: Obagi's proprietary ingredient complex delivers a concentrated blend of nourishing actives directly to the lash follicle, supporting the appearance of thicker, more defined lashes with consistent daily use.
• Biotin for Lash Strength: Biotin, a key B-vitamin known for its role in hair health, helps fortify the lash structure, reducing the appearance of sparse or fragile lashes and supporting a visibly fuller lash line over time.
• Visibly Thicker and More Defined Lashes: Formulated to accentuate the natural look of lashes, this serum enhances lash definition and density for a more dramatic, wide-eyed appearance without the need for extensions or falsies.
• Suitable for All Skin Types: Formulated for normal to dry, normal to oily, and combination skin types, making it a universally compatible addition to any lash care routine.
• 3-Month Supply Per Bottle: Each 1-pack provides a full 3-month supply, delivering consistent, cumulative results with daily use and exceptional value for a premium lash treatment.
• Trusted Obagi Formulation: Developed by Obagi, a globally recognized leader in clinically proven skincare, this serum carries the brand's hallmark commitment to efficacy, safety, and dermatologist-trusted performance.

How to Use

Apply once daily to clean, dry skin along the upper lash line, as close to the lash base as possible. Use the precision applicator to draw a thin, even line from the inner to outer corner of the eye. Allow to dry completely before applying any other eye products. For best results, use consistently every evening as the final step in your nighttime skincare ritual. Visible improvement in lash appearance is typically seen with continued daily use over several weeks.

Store in a cool, dry place away from direct sunlight. Keep the cap tightly closed when not in use. For external use only. Avoid getting product directly in the eye.
