Understanding INCI: Decoding Skincare Ingredient Lists


When you pick up a skincare product and flip it over to check the ingredient list, you might be met with a series of cryptic abbreviations and scientific names. These seemingly complex codes are part of the International Nomenclature of Cosmetic Ingredients (INCI) system. INCI provides a standardized way of listing ingredients in personal care products, making it easier for consumers to understand what they are putting on their skin. In this article, we will delve into the basics of INCI and how it works in relation to skincare ingredients.



First is Highest Amount: The INCI system follows a specific order for listing ingredients, and the first one listed is typically present in the highest amount within the product formulation. This means that the ingredients at the beginning of the list are more abundant than those at the end. For instance, if water (aqua) is listed as the first ingredient, it indicates that the product's formulation primarily consists of water.


INCI Nomenclature: The INCI nomenclature is a language of its own. It uses scientific names, Latin names, and standardized English names to describe ingredients. This ensures that ingredient names are consistent across different countries and languages. For example, Retinol, a form of vitamin A, is listed as "Retinol" in the INCI system, regardless of the brand or country of origin.


Common Ingredient Names: To make it easier for consumers to understand the ingredient list, many brands also include common names alongside the INCI names. These common names are often provided in parentheses after the INCI name. For example, "Tocopherol (Vitamin E)" clarifies that the ingredient Tocopherol is commonly known as Vitamin E.

Active vs. Inactive Ingredients: While the INCI system does not differentiate between active and inactive ingredients, brands often highlight active ingredients separately on product packaging or marketing materials. Active ingredients are the key components responsible for delivering specific benefits to the skin, such as retinol for anti-aging or salicylic acid for acne treatment. It's essential to understand that even inactive ingredients play a crucial role in product stability, texture, and overall performance.


Potential Allergens: INCI lists also help individuals with known allergies or sensitivities identify potential triggers. By examining the ingredient list, individuals can avoid substances that may cause adverse reactions. Allergens such as fragrance components or specific plant extracts are usually listed towards the end of the ingredient list.


Decoding skincare ingredient lists through the INCI system empowers consumers to make informed decisions about the products they use on their skin. Understanding the order of ingredients, the nomenclature used, and the presence of potential allergens enables individuals to choose products tailored to their preferences and needs. The INCI system provides transparency and consistency, serving as a valuable tool for both consumers and manufacturers in the world of skincare.
