Pore-clogging & fungal-acne cheat sheet
The ingredients most likely to clog pores or feed fungal acne, what to look for instead, and how to read a label in a minute. Print it, or save it as a PDF.
1. Pore-clogging (rated 3–5 of 5)
2. Fungal-acne triggers
Malassezia yeast can't make its own fatty acids, so it feeds on those in your products (mainly chains of 11–24 carbons), on their esters, and on polysorbates.
Free fatty acids
Esters & lanolin derivatives
Emulsifiers, polysorbates & surfactants
Plant oils & butters
Other
3. Generally safe (low pore-clog rating, not a known yeast food)
4. Reading a label in a minute
- Position matters. The first ten or so ingredients make up most of the formula. A high-rated ingredient near the end is usually a trace amount.
- Look up the INCI name. Coconut oil is listed as Cocos Nucifera Oil, shea butter as Butyrospermum Parkii Butter. Our scanner knows the aliases.
- Don't judge by the ending. "-ate" is not a rule: isopropyl myristate is a problem, sodium hyaluronate and sodium PCA are not. Check the actual ingredient.
- Fatty alcohols are different. Cetyl, cetearyl and stearyl alcohol are moisturising, not drying, and are generally considered fine for fungal acne.
- Leave-on vs rinse-off. A pore-clogger in a face wash matters much less than one in a moisturiser, sunscreen or foundation.
- Ratings are a screen, not a verdict. The scale comes from old rabbit-ear tests. Concentration, the whole formula and your own skin matter. Introduce one new product at a time.
