What do comedogenic and non-comedogenic mean?
Comedogenic refers to a substance’s tendency to cause open comedones (blackheads) and closed comedones (whiteheads) by blocking the pores of the skin. The term is used by cosmetic manufacturers to rank products
How was the scale devised?
Back in the 1970s, tests were carried out on rabbits’ inner ears. Because they’re more sensitive than human skin, responses were considered to be faster and more convenient than human trials. These tests have since been proven to have delivered a lot of false positives. For a start, rabbits’ ears have larger pores than humans and what was deemed comedogenic in the animals didn’t always translate to human behaviour. Crucially, if an ingredient proved to be comedogenic on its own, it didn’t automatically mean it would be comedogenic when mixed with other substances. Equally, ingredients that were non-comedogenic could become comedogenic when mixed together.
What lessons can be learned?
Your skin is unique. What is comedogenic to one person may not be to the next. Your skin’s response may differ because of your skin microbiome, activity levels and/or exposure to different environmental conditions.
The source and strength of the ingredient can change its comedogenicity. With natural extracts, for example, each batch may have slightly different levels of chemicals. The best makeup for oily, acne-prone skin will always be non-comedogenic. Make sure you read the label carefully before buying.
