The concept of \u2018\u2018acne cosmetica\u2019\u2019 was developed to link the use of certain ingredients to comedone formation. Various clinical research methods have been suggested for the effective screening of an ingredient that can worsen acne or acneiform eruption and confirm its clinical relevance as to whether it is used as a non\u2010comedogenic claim. Although comedogenicity assessment has not yet been established, attempts have been made to evaluate the comedogenicity of cosmetic ingredients and find the most appropriate method to evaluate comedogenicity in human skin.<\/jats:p><\/jats:sec><jats:sec><jats:title>Materials and methods<\/jats:title><jats:p>Total 6 participants were included in the study.
