What is Acne and Pimples
Acne vulgaris: The medical term for common acne is an inflammatory disease of the skin, resulting from the action of hormones and other substances on the skin's oil glands and hair pores. Is the generally used name for pores blocked by sebum, also known as pimples, whiteheads, blackheads, nodules spots, zits or cysts that can appear on face, chest, back, shoulders and upper arms or other body parts.
Acne affects most teenagers in puberty to some extent but, this disease is not restricted to any age group, sex or race. Acne thus tends to disappear, or at least decrease, after the teenager reaches their early twenties. There is, however, no way to know in advance how long it will take to disappear completely, and a good number of adults will continue to suffer from acne, into their 30s and 40s and even beyond. When severe, acne can lead to serious and permanent scarring but the big problems with acne are the disagreeable look of pimples and the scars they may leave, being a source of significant emotional distress.
Troublesome acne lesions can develop
Comedones - People with acne often have a variety of lesions. The basic acne lesion, called the comedo or comedones, is simply an enlarged hair follicle, often called pores. If the comedo, stays below the skin, it is called a closed comedo or whitehead. A comedo that reaches the surface of the skin and opens up is called an open comedo or blackhead.
Papules – Papule is a small but solid , red spot on the surface of the skin that does not contain pus, unlike pustules. Very small papules can also appear in clusters, due to the tissues response to acne.
Pustules – Pustules or pimples are small inflamed elevations of the skin that contain pus. That pus is a combination of white blood cells, dead skin cells and bacteria. Pustules are normally formed around pores and hair.
Macula – Macula or macule is a discolored spot or area on the skin left behind by an acne lesion. A group of maculas gives the face an inflamed aspect.
Nodules – A nodule is a deep acne lesion, and can be one of the most painful lesions. Nodules have a tendency to expand into the deeper layers of the skin and are known to lead to tissue destruction. Can be very hurtful to remove, leave scars behind and can take months to get rid of them. Nodular acne is a very severe acne that is treated only with isotretinonin.
Cysts – An acne cyst are deep, painful, can appear similar to a nodule, but is pus-filled lesions and contain liquid like that found in pustules. However, cysts are larger than pustules and can be infected. Dermatologists often have ways of lessening swelling and preventing scarring.
