Comedogenic ingredients to avoid in acne-prone skin

Comedogenic ingredients can lead to comedones or black/whiteheads in oily or acne prone skin as determined by rabbit ear assay. You should avoid comedogenic ingredients if you have resistant pimples or comedones beyond 25 years of age.

Comedogenic ingredients are graded, from 1-5, 1 being least comedogenic and 5 most. As a general rule, you should avoid the use of comedogenic ingredients with grades 3-5 even if they appear at the end of the ingredient list. However, comedogenic ingredients with grade 1-2 should be avoided if they appear on top of the ingredient list, which meaning there concentration is high enough to occlude your pores.

Despite the presence of comedogenic ingredients, the final product might lose comedogenicity if mixed with other solvents or diluted to lower concentrations. Therefore, a good idea would be to look for a product with the label “NON-COMEDOGENIC”.

In this article, we have listed list comedogenic ingredients.
