Some of the different types of zits are:
• Whiteheads – These are very small and remain under the skin, appearing as a small, flesh-colored papules.
• Blackheads – These are clearly visible; they are black and appear on the surface of the skin. Some people mistakenly believe they are caused by dirt, because of their color, and scrub their faces vigorously – this does not help and may irritate the skin and cause other problems.
• Papules – These are small, solid, rounded bumps that rise from the skin. The bumps are often pink.
• Pustules – These are pimples full of pus. They are clearly visible on the surface of the skin. The base is red and the pus is on the top.
• Nodules – These are having morphologically similar structure to papules, but larger. They can be painful and are embedded deep in the skin.
• Cysts – These are clearly visible on the surface of the skin. They are filled with pus and are usually painful. Cysts commonly cause scars.
