Answer

Answer

Clinically, the features of acne can have many forms. Closed comedones are approximately 1-3 mm in diameter. Open comedones are approximately 2-5 mm in diameter, and this dark core is a packed combination of melanin, oxidized lipids, keratin, and bacteria. Occasionally, several adjacent units may coalesce and create deep dermal abscesses.
