Frequently Asked Questions
What is this serum meant to do?
It is designed to improve the look of thinning, patchy, or over-tweezed brows, helping them appear fuller, thicker, and more defined. It uses Obagi's Nouri-Plex technology with biotin, peptides, and hyaluronic acid.
How do I apply it?
On clean, dry skin at night, apply the serum starting at the root of the brow and follow its natural shape. Wait about 90 seconds for it to dry before continuing with the rest of your routine.
How long before I notice a difference?
Brow improvement is gradual, so plan on consistent nightly use over roughly 8 to 16 weeks to see fuller-looking brows. Results build with continued use.
Does it contain a prostaglandin ingredient?
Yes, it includes dehydrolatanoprost, a prostaglandin-analogue ingredient. It is a cosmetic brow serum, so if you have eye sensitivities or concerns, it is best to consult your doctor before starting.

Obagi is the fourth eyebrow serum I have tried and is the only one which has really enhanced growth and filled out the sparse areas. I highly recommend!
