Rough Nature Bartserum

We rank results with INCI-level analysis first, then fall back to the strongest active matches and closest alternatives so every product page still shows comparable options. Fallbacks stay within the same category as the source product, so cleansing balms only surface cleanser dupes instead of adjacent product types. Active Match % measures shared science-backed actives. Formula Similarity % measures total ingredient overlap when full INCI lists are available.
