OBAGI Medical Nu-Cil Eyelash Enhancing Serum

Reveal beautiful lashes from root to tip. Obagi Nu-Cil is a once-daily cosmetic serum designed to enhance the look of thinning, sparse lashes for a fuller, thicker, and more defined appearance — with results that continuously build day after day.

Powered by proprietary NouriPlex Technology, a unique blend of four key ingredients that work together to target the growth phase of the lash cycle and nourish lashes for improved condition, thickness, volume, and density.

Key ingredients:

• Biotin (Vitamin B7): Supports keratin production for the look of thicker, fuller lashes

• Sodium Hyaluronate: Nourishes and moisturizes for more voluminous-looking lashes

• Panthenol: Hydrates, softens, and enhances shine

• Proprietary lipid compound: Helps support the appearance of the lash line

Clinically proven results: In a 16-week blinded clinical study, participants saw visible improvement — with 89% reporting thicker-looking lashes and 89% reporting more densely packed lashes. Many users notice results in as little as 8 weeks, with continued improvement over time.

Skin-friendly formulation: Fragrance-free and ophthalmologist tested.

How to use: Nightly, after cleansing, apply a thin layer to the base of the upper lash line. Wait about 90 seconds for the product to dry completely before applying other products. Replace the applicator when it no longer has visible product.
