Paste a skincare or makeup ingredient list and see which ingredients may clog pores. Most checkers give one number with no source. This one shows which lab studies and published lists flag each ingredient, the rating each gave, what was tested, and how many sources agree. The studies often disagree, and you see that too.It also checks a list for fungal acne (Malassezia), using lab tests that show which yeast species grew on each ingredient.Free, no sign-up. The check runs in your browser, so your ingredient list is never sent anywhere. Share links keep the list in the link itself.Every rating traces to a named source; nothing is from memory.
