How We Read Ingredient Labels

Our reviews rely on a few working definitions that keep the analysis consistent. When we say a product is "natural," we mean the formula uses plant-derived ingredients as its primary base, not that every component comes from a botanical source. "Organic" refers to certified agricultural inputs, usually verified by COSMOS or Natrue. We do not treat "clean beauty" as a technical term because it has no legal definition; we only use it when quoting a brand's own marketing language.

Fragrance-free means no added perfume oils, not no scent at all Preservative system covers the full blend, not a single listed ingredient Patch test results come from our panel, not from lab irritation scores Eco-certified refers to the finished product, not each raw material
