Pore-Clogging Ingredient Checker — Is Your Skincare Causing Breakouts?

A pore-clogging ingredient, also called a comedogenic ingredient, is a substance that can block hair follicles and pores when applied to skin. This blockage traps oil, dead skin cells, and bacteria — leading to blackheads, whiteheads, and acne breakouts.

Comedogenic means a product or ingredient has a tendency to cause comedones, which are clogged pores. Non-comedogenic means the product is formulated to minimize that risk. However, "non-comedogenic" is not a regulated term, so products can still contain problematic ingredients.

Yes. "Non-comedogenic" is not FDA-regulated, so brands can use it freely regardless of their formulation. Always check the ingredient list — even products marketed as non-comedogenic can contain known pore-cloggers like coconut oil, isopropyl myristate, or lanolin.

The most frequently flagged comedogenic ingredients include isopropyl myristate, isopropyl palmitate, coconut oil, cocoa butter, lanolin, sodium lauryl sulfate, wheat germ oil, and dimethicone. These appear in many everyday moisturizers, sunscreens, and makeup products.

Yes, for most acne-prone skin types. Coconut oil is high in lauric acid and rates a 4 out of 5 on the comedogenicity scale, making it one of the more well-known pore-cloggers. Despite its popularity as a natural ingredient, it is generally not recommended for acne-prone skin.

Yes. Comedogenicity depends partly on concentration — an ingredient listed near the end of a product's ingredient list is present in a smaller amount and may pose less risk than one listed near the top. However, even small amounts can trigger breakouts in highly sensitive or acne-prone skin.

Ingredient lists are required by law to appear on product packaging. You can also find them on the brand's website, on retailer product pages, or through databases like INCI Beauty and CosDNA.

Non-comedogenic is a marketing term with no legal definition. Acne-safe is a stricter standard used by acne specialists, meaning a product has been reviewed and cleared of known pore-clogging ingredients at concentrations likely to cause breakouts. Acne-safe is the more reliable standard for acne-prone skin.

Yes. This is called acne cosmetica — acne triggered or worsened by topical products such as moisturizers, makeup, sunscreen, or hair care. It typically appears as small, uniform bumps and is often mistaken for hormonal acne.
