What is the definition of a comedogenic ingredient?

A comedogenic ingredient is defined as one that is likely to clog pores, which can lead to the development of acne and other skin issues. These ingredients can interfere with the natural exfoliation process of the skin, causing dead skin cells to accumulate and block hair follicles.

In skincare, it is essential to identify and avoid comedogenic substances, especially for individuals with oily or acne-prone skin. By using products free from these types of ingredients, one can help maintain clearer skin and prevent breakouts. This understanding is crucial for estheticians when recommending products tailored to a client's specific skin type and conditions.

The other definitions relate to beneficial properties for skin, such as enhancing moisture, reducing inflammation, or being suitable for sensitive skin, but they do not encompass the specific attribute of potentially causing pore blockage that defines comedogenic ingredients.
