• Visible improvement reported at 8 weeks for many participants
• More pronounced results observed at 12 weeks in trials
• Daily application increases the chance of consistent, cumulative change

What ingredients are in Nu-Cil and what do they do for brows?

Nu-Cil uses NouriPlex Technology, a combination of four high-performance ingredients chosen to support the appearance of healthy-looking brows. Key actives include Biotin for hair-supporting nutrients, Sodium Hyaluronate for hydration, Panthenol to condition hair fibers, and a lipid compound to improve texture and manageability.

• Biotin — supports the look of stronger, more substantial brow hairs
• Sodium Hyaluronate — hydrates the brow area to reduce dryness and improve feel
• Panthenol — conditions hairs for smoother texture and easier styling
• Lipid compound — helps improve overall brow appearance and manageability

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

Apply the serum once daily to clean, dry brow skin, using the precise applicator to target sparse areas and along the brow line. Allow the formula to absorb before layering other products or makeup to ensure maximum contact with the skin and hairs.

• Use on cleansed, dry brows to improve absorption
• Apply sparingly along the eyebrow line and to patchy areas
• Allow time to dry before applying other cosmetics
• Consistency—apply daily for the duration indicated to match study timelines

Obagi formulates Nu-Cil to be dermatologist tested and physician endorsed, reflecting the brand's long-standing clinical approach to skincare. While the formula is designed for broad tolerability, anyone with known sensitivities should patch-test first or consult a skincare professional if concerned.

• Dermatologist tested and physician endorsed formulation
