Comedones are small corneal spots, 1 to 3 mm in size, located at the opening of the pilosebaceous canals. When they persist or worsen, they may lead to the development of spots. Comedones are commonly called blackheads, due to their colour, which is produced by the oxidation of lipids in the sebum.
