Acne

Blackheads (Open Comedones)

The dark surface of a blackhead is oxidised material, not trapped dirt.

In plain language

What this term means.

Open comedones develop when a blocked follicle remains open at the surface. The contents darken through oxidation.

Frequently asked

Questions to take into consultation.

A photograph can document appearance but may not show texture, depth, scalp findings or warning signs. A diagnosis and personalised plan may require history and in-person examination.

Not usually. The appropriate pathway depends on the cause, severity, skin or hair characteristics, previous treatment, medical suitability and the result you hope to achieve.
