Comedogenicity refers to the ability of an ingredient or a skincare product to block pores, thereby promoting the emergence of open or closed comedones. All skin types can be affected, although oily and acne-prone skin are particularly susceptible. Identifying components to avoid and prioritising non-comedogenic care is crucial for maintaining clear and balanced skin.
How can one determine if an ingredient is comedogenic?
There exists a scale of comedogenicity that ranks ingredients from 0 (non-comedogenic) to 5 (highly comedogenic).
Are all vegetable oils comedogenic?
No, it depends on the vegetable oils. Some, like coconut oil, can indeed clog the skin's pores, but others, such as jojoba oil, are light and non-comedogenic.
Are organic skincare products less comedogenic?
No, there is no link between the organic nature of a cosmetic product and its risk of comedogenicity.
Are sun creams comedogenic?
This depends on the sun creams. Today, there are sun protection products with a light texture that are non-comedogenic and suitable for oily or acne-prone skin.
Can an ingredient be comedogenic for one person and not for another?
Yes, the reaction depends on the skin typology and individual sensitivity.
Can a product become comedogenic over time?
Yes, this is possible if the product oxidises over time.
