Acne is perhaps the most common disease of puberty though sometimes occurs in adult life, and it's characterized by inflammation of the sebaceous glands. The common acne, which is the one that concerns the most people, has the unique characteristic of the comedones, open (blackheads) and closed (whiteheads) that fill the pilosebaceous follicle and is the mildest of the types.
Main types of acne:
In the Inflammatory acne, papules may be created, ie small red pimples, and pustules, pimples with pus. More intense and often painful inflammatory lesions are nodules and cysts that may remain on the skin for several weeks.
In the non-inflammatory acne only are observed only the comedones, open or closed as mentioned above, without development in inflammatory acne lesions.
The most common type is the "common acne" and it's localized in areas rich in sebaceous glands (particularly face-back-shoulder-thorax). Acne disappears gradually in adulthood and usually occurs between the ages of 14-17 years for girls and 16-19 for boys, but without restrictions for the time limits especially in women.
The causes of acne are not known although it's a multifactorial disease. The factors that involved in its appearance are:
1. family history (inheritance)
2. hormonic disorders
4. After skin irritation
5. use of certain drugs (lithium, androgens)
6. use of enhancing and various drugs
7. use of fatty cosmetics
It highly affects everyone's psychology, that's why patients should to be patient because it is about a persistent and time consuming condition that can lead to depression. When it appears during puberty, that people are quite insecure, can lead to suicide if treatment is delayed.
Four are the factors that involved in the pathophysiology of the disease:
1) The overproduction of sebum by the glands of the skin, partially genetically determined, mainly by the local action of androgens and particularly of the dihydrotestosterone after the enzymatic action of the 5aplha-reductase.
2) The Propionobacterium acnes which is found inside the pilosebaceous follicles and produces lipases that cleave fatty acids of the sebum and considered that are essential factors in the pathogenesis of acne.
3) The inflammation, both of the P.acnes and the accumulation of sebum and the pressure to the walls of the fofficle.
4) The narrowing exit of the pilosebaceous follicle, by disorder of the keratinization of the cells.
Acne requires prompt treatment to avoid relapses and not leave scars. Moreover, if left untreated or not selected the right treatment, acne can persist for many years. Even the "prompt treatment", ie in the beginning of the problem visit a doctor, dermatological center or hospital, even if you think that the problem is not very serious, is a safe and permanent solution to the problem. Acne is a disease, not just a cosmetic problem. It needs medical help, and there is no reason to be embarrassed about your problem.
