International Nomenclature of Cosmetic Ingredients / Ingredient List
The standardised international naming system for cosmetic and personal care ingredients, established by the Personal Care Products Council and adopted globally. INCI names are listed on product labels in descending order of concentration — the ingredient present in the highest amount is listed first, the lowest last. Ingredients present at 1% or below may be listed in any order. Understanding INCI listings allows consumers to identify active ingredients, potential irritants, and assess product quality.
Key reading tips: ingredients above hyaluronic acid or other actives in the list are present in meaningful concentrations; ingredients below the preservative concentration threshold (typically near the end) are likely present in trace amounts and may have limited efficacy.
