    Area of Science:

    • Dermatology
    • Cosmetic Science

    Background:

    • Acne cosmetica, a form of acne vulgaris, is frequently exacerbated by cosmetic products.
    • Identifying non-comedogenic cosmetic ingredients is essential for managing acne-prone skin.

    Purpose of the Study:

    • To identify comedogenic ingredients in cosmetics.
    • To formulate a non-comedogenic cosmetic product for acne patients.
    • To evaluate the efficacy of the non-comedogenic formulation in reducing acne cosmetica.

    Main Methods:

    • Testing various cosmetics, lanolin fractions, and emulsifiers for comedogenicity in rabbits.
    • Formulating a cosmetic product using identified non-comedogenic ingredients.
    • Clinical evaluation of the formulation's impact on acne cosmetica in acne-prone women.

    Main Results:

    • Several common cosmetic ingredients, including lanolin derivatives, butyl sterate, isopropyl myristate, and sodium lauryl sulfate, were found to be comedogenic.
    • A non-comedogenic cosmetic formulation was successfully developed.
    • The incidence of acne cosmetica decreased from 25% to less than 5% in patients using the new formulation.
    • Sulfur was not confirmed as a potent acnegen in this study.

    Conclusions:

    • A significant number of commonly used cosmetic ingredients possess comedogenic properties.
    • The developed non-comedogenic cosmetic formulation effectively reduces acne cosmetica in acne-prone individuals.
    • Further research may be needed to clarify the role of ingredients like sulfur in acne development.
