Brow Serum
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.
