The INCI list allows you to recognize the names of cosmetic ingredients, but does not reveal the entire formula in percentage terms. It is useful for comparing labels and finding a specific substance. However, it is not worth turning it into a ranking in which a single difficult name determines the quality of the product.
Read the correct version listing
Check full name, capacity and variant. The photo of the old packaging may contain a different list than the product you currently have in front of you. If there are discrepancies, do not combine both lists into one. Keep a photo of the label and explain which batch or version the available data applies to.
The order is not a percentage table
In cosmetics, ingredients are generally listed in descending order of weight, with exceptions provided for specific groups and low concentrations. The position on the list alone does not allow the exact content to be calculated. Do not add percentages that have not been declared by the manufacturer.
Name and role in the recipe
One substance can perform different functions, and the feeling of the finished product depends on the entire system. Checking individual names is helpful, especially if you have a known allergy. However, it is not sufficient to predict the consistency, comfort or effectiveness of an entire formula on a specific skin.
How to ask questions about composition
Indicate the exact INCI name and what you want to determine: the presence of the ingredient, the source of the current list or the declared concentration. This gives a better answer than asking whether the composition is good. The reaction history is also important for individual tolerance, not just the similarity of the two product lists.
