Types of AcneThough all pimples start the same way, they can take many forms and may react differently for different people. |

Closed comedo, or whitehead: If the plugged follicle stays
below the surface of the skin, the lesion is
called a closed comedo, or whitehead. They usually appear on the skin as small, whitish bumps. You can view a diagram of a whitehead on the what is acne page. Whiteheads are normally quicker in life cycle than blackheads.
Open comedo, or blackhead: If the plug enlarges and
pushes through the surface of the skin, it's called an open comedo, or blackhead. The plug's dark appearance is not due to dirt, butrather to a buildup of melanin, the skin's dark pigment.
INFLAMMATORY ACNE :
Papule: The mildest form of inflammatory acne is the papule, which appears on the skin as a small, firm pink bump. These can be tender to the touch, and are often considered an intermediary step between non-inflammatory and clearly inflammatory lesions.
Pustule: Like papules, pustules are small round lesions; unlike papules, they are clearly inflamed and contain visible pus. They may appear red at the base, with a yellowish or whitish center. Pustules do not commonly contain a great deal of bacteria; the inflammation is generally caused by chemical irritation from sebum components such as fatty free acids.
Nodule or Cysts: Large and usually very painful, nodules are inflamed, pus-filled lesions lodged deep within the skin. Nodules develop when the contents of a comedo have spilled into the surrounding skin and the local immune system responds, producing pus. The most severe form of acne lesion, nodules may persist for weeks or months, their contents hardening into a deep cyst. Both nodules and cysts often leave deep scars.
Acne Rosacea : Rosacea affects millions of people, most of whom are over the age of 30. It appears as a red rash which is normally confined to the cheeks, nose, forehead and chin. The redness is often accompanied by bumps, pimples, and skin blemishes. Blood vessels may also become more visible on the skin. Blackheads are not a part of rosacea. It is more prevalent in women, but often more severe when found in men. Left untreated, it can cause swelling of the nose and the growth of excess tissue, a condition called rhinophyma. Treatment is often different for rosacea than for acne, and it is important that you consult a doctor can determine if what you are experiencing is acne vulgaris or rosacea.
SEVERE FORMS OF ACNE :
These form of acne are rare, but they are a great hardship to the people who experience them, and can be disfiguring--and, like all forms of acne, can have psychological effects on the sufferer.
Acne Conglobata: This is the most severe form of acne vulgaris and is more common in males. It is characterized by numerous large lesions, which are sometimes interconnected, along with widespread blackheads. It can cause severe, irrevocable damage to the skin, and disfiguring scarring. It is found on the face, chest, back, buttocks, upper arms, and thighs. The age of onset for acne conglobata is usually between 18 and 30 years, and the condition can stay active for many years. As with all forms of acne, the cause of acne conglobata is unknown. Treatment usually includes isotretinoin (Accutane), and although acne conglobata is sometimes resistant to treatment, it can often be controlled through aggressive treatment over time.
Acne Fulminans: This is an abrupt onset of acne conglobata which normally afflicts young men. Symptoms of severe nodulocystic, often ulcerating acne are apparent. As with acne conglobata, extreme, disfiguring scarring is common. Acne fulminans is unique in that it also includes a fever and aching of the joints. Acne fulminans does not respond well to antibiotics. Isotretinoin (Accutane) and oral steroids are normally prescribed.
Gram-Negative Folliculitis: This condition is a bacterial infection characterized by pustules and cysts, possibly occurring as a complication resulting from a long term antibiotic treatment of acne vulgaris. It is a rare condition, and we do not know if it is more common in males or females at this time. Fortunately, isotretinoin (Accutane) is often effective in combating gram-negative folliculitis.
Pyoderma Faciale: This type of severe facial acne affects only females, usually between the ages of 20 to 40 years old, and is characterized by painful large nodules, pustules and sores which may leave scarring. It begins abruptly, and may occur on the skin of a woman who has never had acne before. It is confined to the face, and usually does not last longer than one year, but can wreak havoc in a very short time.
