What skin condition is characterized by closed comedones, often appearing as small, white bumps?

The skin condition characterized by closed comedones that appear as small, white bumps is known as milia. Milia are tiny cysts that form when keratin becomes trapped beneath the surface of the skin. They often occur around the eyes, cheeks, and forehead and are very small, firm, and white or yellowish in appearance. Their closed nature distinguishes them from open comedones, such as blackheads, which have an open pore.

Understanding milia is crucial for estheticians, as they require a different treatment approach compared to other types of acne lesions. Unlike acne vulgaris, which can include a range of lesions such as papules, pustules, and comedones, milia are not inflammatory in nature and are not typically best treated using conventional acne treatments. Instead, milia often require mechanical extraction by a trained professional or specific topical treatments that encourage exfoliation to prevent future formations. Recognizing this distinction is vital for effective skin care and treatment planning.
