Unveiling Skincare Ingredient Networks

Abstract

The cosmetic industry has experienced substantial growth, driven by consumers' increasing demand for effective and innovative skincare products. This study examines the relative importance of various cosmetic ingredients across five product categories: cleansers, eye creams, face masks, moisturizers, and sun protection products. Using the PageRank algorithm, we analyze ingre-dient significance by considering their occurrence and co-occurrence in a data-set of 1,472 cosmetic products sourced from Sephora. Our findings reveal key multifunctional ingredients such as water, oils, and plant extracts, which are frequently used across different categories due to their moisturizing, antioxi-dant, and soothing properties. Additionally, specialized ingredients like zinc oxide in sun protection products highlight the industry's focus on targeted skin-care needs. The results provide valuable insights for formulators, researchers, and consumers, aiding in the development and selection of high-performance skincare products.
