INCI Name
Definition
International Nomenclature of Cosmetic Ingredients. The standardised Latin/scientific names that must appear on cosmetic labels globally. Every ingredient in a product has a unique INCI name regardless of the brand's marketing terminology.
Why it matters for dupe shopping
INCI names let you compare two products objectively. 'Hyaluronic Acid' and 'Sodium Hyaluronate' are different molecules with different skin penetration depths — INCI names expose this where marketing language obscures it.
