Types of Acne Pimples

Acne occurs in all age groups and races. Because hormones play a part in its formation, teenagers and women experiencing hormonal fluctuations due to pregnancy, birth control pills or the menstrual cycle are common victims. Because acne can leave long-lasting scars, it is important to understand its types and how they affect the skin.

Comedones

Comedones, often referred to as blackheads and whiteheads, occur when pores become blocked by oil and dead skin cells. The Mayo Clinic says that when comedones are open to the skin surface, they are called blackheads. This is because oxygen causes the oil plug to appear black. Closed comedones are called whiteheads. They appear as raised flesh-colored bumps.

Papules

According to the University of Maryland Medical Center, papules are a type of acne that appears as an inflamed lesion. They are typically small, measuring less than 1cm across. Papules are solid and tender and do not have a head.

Pustules

Pustules appear as small, raised, pus-filled lesions on the surface of the skin. The University of Maryland Medical Center explains that this form of acne is common and may develop anywhere on the body. However, pustules typically occur on the face, back, shoulders and breastbone.

Nodules

Nodules are usually larger and more painful than other types of acne. Acne.org states that nodules are hard acne bumps beneath the surface of the skin. They can remain beneath the skin for several months. Nodules that are left untreated can lead to scaring and impaction. Never attempt to remove or squeeze a nodule yourself. Doing so can cause serious damage to the skin. Instead, seek the help of a dermatologist or doctor.

Cysts

An acne cyst can form from a papule or nodule. The American Academy of Dermatology states that cysts are an inflamed boil-like bump beneath the skin. They are tender to the touch and may be filled with thick, yellowish pus. This is usually the result of infection. Cysts that occur close together can destroy the cell layers beneath the skin, creating inflamed tunnels. As with a nodule, never attempt to drain a cyst on your own. To prevent serious injury and further infection, have a physician treat the cysts under sterile conditions.
