What is a microcomedo primarily made up of?

A microcomedo is primarily composed of dead skin cells, bacteria, and fatty acids derived from sebum. This formation occurs in the hair follicles where the buildup of keratinized cells, combined with the natural oils produced by the skin, creates a plug. This plug can become an environment for bacteria, leading to acne formation.

Understanding this composition helps in recognizing how microcomedones can develop into more visible forms of acne if not properly managed. It highlights the importance of exfoliation and maintaining skin hygiene to prevent the accumulation of these elements that contribute to microcomedo formation.
