👉 Adopted pimples, also known as "foreign-derived comedones," occur when dead skin cells and sebum accumulate beneath the surface of the skin, often due to clogged pores from external factors like makeup, dirt, or environmental pollutants. Unlike natural comedones that form within the skin, adopted pimples are introduced through external sources and typically appear as small, round bumps or whiteheads on the face. These pimples can be particularly noticeable in areas with high exposure to these external irritants, such as the T-zone (forehead, nose, and chin). Over time, repeated clogging can lead to inflammation and the formation of more severe acne lesions.
