What is the Clinical Appearance of a Comedone?
Closed comedones or white heads present as skin colored, white or slightly reddish bumps on the facial skin. Open comedones or blackheads have wide rimmed opening with a characteristic black plug covering the opening. This black color is not due to dirt, but caused by oxidization of the sebum when it comes in contact with the atmospheric oxygen. The treatment of mild comedonal acne does not warrant the use of oral medications; topical applications will work well in most cases.
