Having non-comedogenic skincare, makeup, and hair products is crucial to having clear skin. You might not even be aware that your moisturizer, foundation, or shampoo could be the reason you can’t fully get rid of acne! Comedogenic ingredients are the ingredients that clog your pores, resulting in different types of acne. Our application allows you to easily check whether the product’s ingredient list contains any pore-clogging ingredients, or if the product is safe to use on acne-prone skin.
