INCI – How to Read the Ingredients of Cosmetics? What to Avoid?

When buying cosmetics, we usually pay attention to the promises on the packaging and the attractive design. However, did you know that the real secret to high-quality cosmetics is often hidden in their ingredients? The components they contain can have a significant impact on your skin and overall health. That’s why it’s important to understand how to read INCI—the International Nomenclature of Cosmetic Ingredients—to properly assess the composition of the products you use.

What is INCI?

INCI stands for "International Nomenclature of Cosmetic Ingredients" and is a standardized system for labeling ingredients in cosmetic products. Every cosmetic product must list its ingredients using INCI, allowing consumers to decipher its composition. This system makes cosmetic ingredients more transparent and accessible to everyone.

Cosmetic Ingredients: What is the Order of Ingredients in INCI?

The INCI list is arranged in descending order of ingredient concentration, meaning that the first ingredients on the list are present in the highest amounts. This is essential to know, as it helps you understand which components dominate the formula.

Ingredients that make up less than 1% of a cosmetic product can be listed in any order within the INCI list. This means that their placement does not necessarily reflect their actual concentration, allowing manufacturers to maintain trade secrecy and keep the exact amount of an ingredient undisclosed to competitors.

Therefore, when reading the composition of cosmetics, it’s important to consider this fact and focus on the main ingredients, which are usually listed at the beginning of the INCI list.

What Ingredients Should Be Avoided in Cosmetics?

• Parabens are some of the most well-known preservatives used in cosmetic products. They can cause allergic reactions and other skin issues. While most parabens are considered safe, it’s best to choose products with low concentrations or those that do not contain them at all.
• Triethanolamine, SLS (Sodium Lauryl Sulfate), and SLES (Sodium Laureth Sulfate) should also be avoided, as they can irritate the skin, causing dryness and redness.
• Pregnant women should be especially cautious. Certain ingredients, such as retinol (vitamin A), may be harmful to fetal development, so it’s advisable to avoid cosmetics containing them during pregnancy.

Conclusion

Understanding how to read cosmetic ingredient lists using INCI is an essential skill for anyone who cares about their health and beauty. Knowing which ingredients to avoid can help you make informed choices when purchasing cosmetics, ensuring skincare that meets your needs and safety standards. Remember, your skin deserves only the best, and knowledge of INCI can help you achieve that.
