Comedogenicity

Comedogenicity refers to an ingredient’s or cosmetic product’s ability to clog pores, thus promoting the development of open or closed comedones. All skin types can be affected, although oily and acne-prone skin are particularly sensitive. Identifying ingredients to avoid and opting for non-comedogenic skincare is essential for maintaining clear, balanced skin.

FAQ about comedogenicity

How can you determine if an ingredient is comedogenic?

There is a scale of comedogenicity ranking ingredients from 0 (non-comedogenic) to 5 (highly comedogenic).

Are all vegetable oils comedogenic?

No, it depends on vegetable oils. Some, like coconut oil, can indeed clog skin pores, but others, such as jojoba oil, are lightweight and non-comedogenic.

Are organic cosmetics less comedogenic?

No, there is no link between the organic nature of a cosmetic product and its risk of comedogenicity.

Are sunscreens comedogenic?

It depends on the sunscreen formulation. There are now sunscreens with a lightweight texture that are non-comedogenic and suitable for oily or acne-prone skin.

Can an ingredient be comedogenic for one person but not for another?

Yes, the reaction depends on skin typology and individual sensitivity.

Can a product become comedogenic over time?

Yes, this can occur if the product oxidizes over time. This is especially true for certain vegetable oils rich in unsaturated fatty acids.

Does comedogenicity depend on concentration?

Yes, an ingredient can be problematic at high concentrations yet neutral at low doses. The balance of the formulation also influences its behavior on the skin. Therefore, comedogenicity is not a fixed property.

Is the term “non-comedogenic” regulated?

This claim is not strictly regulated. It is based on internal testing.

Is comedogenicity the same as occlusivity?

Not quite. An ingredient occlusive or film-forming limits water loss by creating a film on the surface. This does not necessarily mean it obstructs the pores.

Is comedogenicity limited to the face?

The phenomenon can also affect the back, the torso, or other areas rich in sebaceous glands.
