About Before You Buy

Before You Buy is a product research website and shopping extension for beauty shoppers, currently in development. The private website preview brings together product facts, feedback concerns and reviewed alternatives for the same buying purpose. On supported Sephora and Ulta product pages, the extension offers a quick review and a link to the same product’s full website report.

Where the picks come from

We analyze retailer-review signals from Sephora and Ulta, sort every mention into a buying factor — breakouts, scent, hydration, texture, how long a bottle lasts — and note which products reviewers single out on each one, within a group of products that do the same job. We never reproduce retailer reviews. Strong, Average and Weak tiers describe the available signals; insufficient evidence stays unknown. Where people have talked about a product on YouTube, we also show the most-liked comments, word for word, with a link to the video.

How we make money

This version provides product analysis without purchase links or affiliate attribution. We may add approved affiliate links later, after validating the product and obtaining the relevant merchant and channel approvals. Commission will not determine which alternatives or ratings we show.

What it won’t do

• Pop up or change the page — it’s a number on its icon until you open it.
• Apply coupons, rewrite links, or touch your cart.
• Run anywhere except Sephora and Ulta product pages.
• Take credit for another creator’s link — it stays quiet for that visit.
