How Brow Review Lab tests eyebrow products

The process

Formula analysis. We read the full ingredient list of every product, identify the actives (peptides, conditioning agents, prostaglandin analogues) and check them against the published research in our glossary.

Hands-on use. Editors use each product in a normal routine: serums daily for a full cycle, gels and pencils through working days, lamination kits following the instructions exactly. We note applicator quality, texture, drying time, comfort and efficiency.

User feedback. We review verified purchaser feedback across retailers and look for consistent patterns, not individual outliers, in results, irritation and ease of use.

Value. Price is weighed against size, dose and how long a product lasts in real use, not against the headline price alone.

Reassessed regularly. Rankings are revisited when a formula changes, a notable product launches, or every 12 months, whichever is sooner.

Editorial standards

No affiliate links. No sponsored placements. Products are purchased at retail, never accepted from brands. Writers disclose any past relationship with a manufacturer, and that writer is excluded from assessing that brand. Full editorial policy · Advertising disclosure.

Every health claim is reviewed by a consultant trichologist before publication. Scores are editorial judgements against the rubric above, not clinical measurements. Corrections are logged at the foot of each article with the date.
