Obagi Nu-Cil Eyebrow Boosting Serum | Brow Density Serum

Over-tweezed, thinning or sparse brows are one of the most common aesthetic concerns Vaiva hears from patients, particularly those going through menopause, on GLP-1 medications, or simply dealing with the effects of years of aggressive shaping. Obagi Nu-Cil Eyebrow Boosting Serum uses the same NouriPlex Technology as the Nu-Cil Eyelash Serum to support the brow follicle environment and the growth phase of the brow hair cycle, for progressively fuller, thicker and darker-appearing eyebrows with consistent daily use.

Clinically evidenced: 100% of participants reported improvement in the appearance of brow fill at 8 weeks. 96% reported improvement in the appearance of brow density and volume at 8 weeks, based on a 2022 blinded study.

Who Is It For?

• Those with thinning, patchy or over-tweezed eyebrows wanting progressive improvement in density and fullness
• Those experiencing brow thinning with age, menopause or GLP-1 medication
• Those who want fuller, more defined brows without pencils, powders or microblading

How Does It Work?

NouriPlex Technology delivers biotin, panthenol, sodium hyaluronate and a proprietary lipid compound to the brow follicle environment. Biotin supports the natural production of keratin, the structural protein of the hair shaft. The lipid compound helps address the appearance of patchy and over-tweezed areas. Consistent daily use supports the brow growth cycle for progressively fuller-looking brows.

Key Ingredients

• NouriPlex Technology (Obagi proprietary): Biotin, panthenol, sodium hyaluronate and proprietary lipid compound that supports brow follicle health and growth cycle activity for fuller-looking, denser brow appearance.
• Biotin: Supports natural keratin production in the brow hair shaft.

Benefits

• 100% of participants reported improved brow fill appearance at 8 weeks
