Skin Type & Concerns
Concerns: Sparse brows, thinning brows, over-plucked brows, age-related brow hair loss, weak or brittle brow hairs
How to Use
Apply once daily — preferably in the evening — to clean, dry eyebrows using the precision applicator. Draw the serum along the brow line from the inner to outer corner. Allow to dry completely before applying any additional brow products. Do not rinse off. Consistent nightly use is key — results are typically visible within 6–8 weeks.
Key Ingredients
-
Peptide Complex — A proprietary blend of amino acid sequences that signal hair follicles to prolong the active growth phase (anagen) of the hair cycle, supporting the appearance of denser, fuller brows
-
Biotin — A B-vitamin essential for healthy hair growth; strengthens hair structure and reduces breakage
-
Panthenol (Vitamin B5) — Deeply conditions brow hairs, adding moisture and improving their overall strength and flexibility
Professional Tips
Results require patience — hair growth cycles are measured in weeks, not days. Apply every evening without skipping for the most consistent results. Avoid applying to the eyelid skin or inside the eye. For lash enhancement, see Obagi Nu-Cil™ Eyelash Enhancing Serum.
