How should cosmetic ingredients be read?

Posted on by Ersin Koseoglu

When we receive a product, the first thing to do is to read the contents. In order to be able to read and understand the contents, some tricks must be known. According to the rules, the content information of cosmetic products must be written with the names INCI (INCI: International Nomenclature of Cosmetic Ingredients) 
. There are thousands of cosmetic raw materials in the market, when all these raw materials are written with INCI names, things get more difficult. If you do not have a background in cosmetic science and formulation knowledge, it is really difficult to understand the ingredients, know their functions, and their effects on our skin or hair.
As understanding the functions and duties of all content requires expertise, it can be a bit difficult to know them. Researches can be made with the Internet channel (google, yandex, wikipedia, newspapers and internet news of unknown sources) about the task and function of each raw material used in the content, but unfortunately, the researches made through these channels are not healthy and can be misleading. The interpretation part of the ingredient list is difficult, but once you know how the ingredients are sorted, things get a little easier.
In cosmetic products, the ingredients start with the raw material used at the highest rate in the formula and continue to decrease. For example, the ingredient used in the first place is the one used at the highest rate in the formula. The ingredients in the last rows are the lowest in the formulation (0.5 - 0.01% and lower concentrations).
The contents at the end are generally preservatives, if there is essence in the product, allergens in essences, chelating agents such as EDTA (they inactivate heavy metals in the water and prevent the deterioration of products), dye CI (expressed by Color Index). substances.
One of the most important points to be examined in the content section of the products should be the order of the active ingredients (such as Hyaluronic Acid, Vitamins, Plant Extracts, Sodium PCA, Glycolic Acid, Salicilic Acid, UVA-UVB sun filters). If these actives are last in the ingredient list, their usage rate is very low and no effects should be expected from these actives. If the actives are at the top or middle of the ingredient list then they are really effective and the product formulation is successful.
