There are various forms of acne, named according to how or why the acne arose. Some of the forms of acne are: acne conglobata (chronic boils); acne fulminans (an extreme form of conglobata); acne cosmetica (caused by cosmetics); acne keloidalis nuchae (from shaving); acne medicamentosa (caused by starting or stopping a medication); acne rosacea (redness on the face); baby acne; hormonal acne; cloracne and the common variety, acne vulgaris (also known as 'puberty spots'). In this article, we will concentrate on acne vulgaris.
Acne vulgaris can be defined as: 'an inflammatory disease of the skin, caused by changes in the pilosebaceous units (skin structures consisting of a hair follicle and its associated sebaceous gland). Acne lesions are commonly referred to as pimples, spots or zits' (see article on "Acne" in Wikipedia).
Acne is most usually found in white Western teens, although it is to be found in every country in the world, so there may be a genetic predisposition to it. It is possible that it could be an abnormal reaction to quite average levels of testosterone. For most afflicted, outbreaks of acne last only until the age of twenty or so, probably only a few years or at the most ten. For other people, however, it can be a life-long problem. It usually appears on the face, upper-chest, upper-arms and back. However, an occasional spot does not constitute acne.
Acne vulgaris manifests itself in many forms, including: whiteheads, caused by pores which are completely blocked, trapping sebum (oil), bacteria, and dead skin cells, causing a white appearance on the surface; blackheads, caused by pores which are only partially blocked, allowing some of the trapped sebum, bacteria, and dead skin cells to slowly drain to the surface (the black colour is not caused by dirt, but is a reaction of the skin's own pigment, melanin, with the oxygen in the air); papules, which are inflamed, red, tender bumps with no head and pustules, which are similar to whiteheads, but are inflamed, and appear as red circles with a white or yellow centre.
Whiteheads do not often last for a long time; blackheads do last a long time and pustules are what people call spots or zits. Severe acne vulgaris is characterized by nodules and cysts. A 'nodule' is a much larger and more painful sort of pustule and can sometimes last for months. Nodules are large, hard lumps just under the skin's surface. They often result in scarring and should never for any reason be squeezed, since this could cause them to last for months longer.
A 'cyst' can appear similar to a nodule, but it is full of pus and has been defined as having a diameter of at least 5mm and, again, can leave scars and cause irritation. Squeezing an acne cyst may cause a deeper infection and more painful inflammation which will last very much longer than if it had not been squeezed. Dermatologists have ways of reducing the swelling and preventing scarring with both nodules and cysts. It is a myth that acne sufferers are not meticulous about their hygiene.
In fact, excessive washing can exacerbate acne. There are many, many useless 'treatments' on the market and many, many old wives' tales, but any good dermatologist would tell you that there is no known cure for acne and that the patient should follow a strict regimen of cleaning until the acne just 'disappears' of its own accord.
