Brow Serum

Written by Reviewed by the SYNC editorial team Published Last reviewed Editorial standards

Brow Serum — a leave-on treatment applied to the brows and often marketed to support the look of fuller, healthier-appearing eyebrows over time. Unlike styling gels, brow serums focus on conditioning the brow area with ingredients such as peptides, panthenol, and botanical extracts. Results, when described, are generally gradual and vary by individual and formula.

Key points

  • Brow serums are conditioning treatments meant for regular, ongoing use rather than immediate styling.
  • Common ingredients include peptides, panthenol, biotin, and plant extracts intended to support the appearance of the brow area.
  • They are typically applied to clean brows once or twice daily, following the product's directions.
  • Cosmetic brow serums differ from prescription products, and claims and results vary widely between formulas.

Frequently asked

How long does it take to see results from a brow serum?

Cosmetic brow serums are generally used consistently over several weeks, and any visible change is gradual and varies from person to person.

Is a brow serum the same as a brow gel?

No, a brow serum is a leave-on conditioning treatment for the brow area, while a brow gel is a styling product used to shape and hold the hairs.
