Comedogenicity Checker

Comedogenicity Checker is a web-based tool designed to help users identify potential pore-clogging ingredients in skincare and cosmetic products. It addresses the need for individuals to assess ingredient lists for comedogenicity by comparing a complete list of product ingredients against a dataset of 351 source-linked records. The tool focuses on exact INCI-name matches and provides the comedogenicity rating, source location, and any evidence limitations for each match found.

A key feature of Comedogenicity Checker is its privacy-focused approach: all ingredient analysis occurs locally within the user's browser, ensuring that ingredient lists are never uploaded, stored, or transmitted. The tool does not require users to create an account or upload any data, and it supports various formats for ingredient input, such as commas, semicolons, line breaks, and bullets. JavaScript is required for the local analysis to function.

For each ingredient match, the tool displays the reported comedogenicity rating along with source notes and evidence limits, enabling users to investigate possible pore-clogging risks. However, it explicitly states that a match does not determine whether a finished product will clog pores or cause acne, and encourages users to consider spelling, alternate INCI names, and consult other qualified sources if ingredients are not found in the dataset.

Comedogenicity Checker is suitable for anyone interested in examining skincare or cosmetic product ingredients for potential comedogenicity, particularly those concerned with acne or sensitive skin. The methodology and full source list used for the dataset are available on the site for further review.
