closed comedo
Plural: comedones (KAHM-uh-dohnz). Also known as whitehead; a follicle impacted with dead cells and solidified sebum, appearing as a small white bump just under the skin surface. Closed comedones have an extremely small surface opening.
A closed comedo, also known as a whitehead, is a type of acne. It occurs when a hair follicle becomes clogged with sebum (oil) and dead skin cells. Unlike an open comedo (blackhead), a closed comedo appears as a small, white or flesh-colored bump on the skin’s surface. Closed comedones usually appear on the face, but they can also occur on the chest, back, and other areas of the body.
There are several factors that can contribute to the formation of closed comedones, including hormonal changes, stress, certain medications, and the use of oily or pore-clogging skincare products. Treatment options for closed comedones include over-the-counter topical medications, prescription medications, and professional treatments such as chemical peels or microdermabrasion. It is important to avoid picking or squeezing closed comedones, as this can lead to scarring and further inflammation. To prevent the formation of closed comedones, it is recommended to maintain a consistent skincare routine that includes gentle cleansing, exfoliation, and the use of non-comedogenic (non-pore-clogging) products.
