Cosmetic Allergy Triggers: List of the Ingredients to Avoid in Skincare

Allergy is a very unpleasant thing. If you use a cosmetic product and see that your skin becomes red, irritated or itchy, this usually indicates that at least one of the components of the product is not accepted by your skin. How to identify an enemy? Our website is here to help. Cosmily checks if the product is free from the most serious allergens and shows the alert if a harmful component is found.

If you see this alert you should use the product wisely. If you want to have a deeper understanding of all the background of how the website works read the article till the end.

Do you know that you can analyze ANY beauty or skincare product just by the componets list? Use our Ingredient Checker Tool for this. Just paste the ingredients list and enjoy a full safety report!

What are the most serious allergens?

An allergic reaction is a very personal thing. The same component may trigger the reaction for one person and can be accepted well by the other. It’s almost impossible to predict how your skin will react to a certain product.

Moreover, almost any component may trigger a negative reaction, even the safest one. Well… It sounds like we will have to include all the cosmetic ingredients in our “warning” list…

Fortunately, most of the ingredients are safe for the vast majority of people. But there are some that tend to trigger negative reaction much more often than the others. These components are marked as “Allergens” by our website. If Cosmily finds one of these components in a product you see an alert.

Below you can find a list of all the cosmetic ingredients that have a high probability to cause a negative reaction.  We don’t say that these ingredients always do this when they contact your skin. Very often, if you are a healthy person and don’t have any health issues, you will not feel any negative aftermath. But if you suffer from allergy we recommend avoiding these components in your beauty and skincare products.

The next question you may ask is: how do you know if the component is really harmful? We use different sources of information, mostly scientific researches.

What if I don’t suffer from an allergy? Should I pay attention to the alerts on the website? The general answer is yes. It’s better to pay attention to this. The website warns you and you have to decide what to do next. The best idea is to try the product on a small area of your skin before you include it into your usual routine. This is a standard and simple way to find out if your skin accepts the product.  

Remember: the concentration matters a lot! If the ingredient is somewhere at the bottom, this usually indicates that the concentration of this component is low and the chance to receive a negative reaction is low too. But if the allergen is in the top of the list, it’s a bad sign.
