Pimples: Papules and Pustules

Unlike hormonal acne, papules are a build-up of infection that is not painful. They will eventually develop a white head, which is when they become pustules. They are often caused by excess oil and can also be seen with rosacea, dermatitis or inflammation in the body that shows as irritation on the skin. While they frequently appear in the T-zone, they can be seen anywhere on the face.
