Obagi Nu-Cil Eyelash Enhancing Serum – Nourishing Biotin Lash Serum for Thicker, Defined Lashes – 0.1 oz

Meet Obagi Nu-Cil Eyelash Enhancing Serum

Experience a lash-first serum designed to nourish lashes along their natural cycle. Built on NouriPlex technology, it blends four high-performance ingredients to support conditioning and gradual enhancement with consistent use, helping you bring out the most from your lashes over time.

In a blind, 16-week study, participants reported visible improvements in lash appearance, including a thicker look and a more densely packed appearance. This suggests the formula may contribute to a fuller-looking lash line with regular application while you continue your routine.

Key ingredients and how they work

• Biotin provides targeted nourishment for lash follicles to support conditioning and resilience.
• Lipid compounds help maintain moisture and flexibility on the lash surface.
• Sodium hyaluronate adds lightweight hydration to keep lashes feeling supple.
• Panthenol (pro‑vitamin B5) conditions lashes for a softer, smoother feel.

What you may notice with regular use

• Lashes may appear fuller and more defined over time.
• The lash line can look more cohesive and balanced as your routine continues.
• Makeup may blend more easily with a defined lash base.
