Black head

A black head (technically known as a comedo) is a yellowish, reddish (with white cap) or blackish bump or plug on a skin. It is caused by an excess of oils that have accumulated in the sebaceous gland's duct typically caused by excessive oil, make up and dirt. The substance found in these bumps mostly consist of keratin (horny epidermis cells) and modified sebum (oily secretions of the sebaceous gland) http://www.encyclopedia.com/html/b1/blackhea.asp:black_head.
