PurScore is an online cosmetics and personal-care comparison platform that helps shoppers assess product ingredients and prices before buying. Its database covers more than 200,000 products, nearly 170,000 ingredients, and hundreds of Polish retailers. Users can search by product or shop, explore categories such as face creams, shampoos, makeup, perfumes, and baby products, and compare prices across participating stores. The platform also helps identify lower-priced alternatives with the same ingredient list.

PurScore assigns products a Score based on ingredient safety, naturalness, and price. Its methodology draws on European Commission CosIng information and open data from Open Beauty Facts, and the site explains how ratings are calculated. Product data is updated weekly, ingredient data monthly, and prices daily. Account features include skin-profile personalization, saved products and routines, family profiles, and price alerts. The site also offers ingredient references, rankings, and educational articles. PurScore describes itself as an informational resource, not a source of medical advice; retailer links may be affiliate links, but commissions do not affect product ratings.
