What Are Pimples (zits, spots)? What Causes Pimples?

A grain, also known as a pimple or a point is a small papule or pustule lesions, small skin or inflammation of the skin - which are the sebaceous glands (sebaceous glands) that are infected with the bacteria, become inflamed and filled of pus.

Pimples are caused when the sebaceous glands at the base of hair follicles become hyperactive, and the most vulnerable parts of the body are the face, back, chest and shoulders. The buttons are tangible signs of acne, especially when an escape.

According to the dictionary Medilexicon:

A button is a small papule or pustule, usually intended to indicate an inflammatory lesion of acne.

What are sebaceous glands?

The sebaceous glands are glands that secrete sebum skin tiny - a waxy substance / oil - to lubricate the skin and hair of mammals (humans are mammals).

Human beings, they are everywhere in the sites of the skin except the palms and soles, and there is a greater abundance of sebaceous glands of the face and scalp. In our eyes, meibomian glands secrete a special type of sebum in tears.

Several medical conditions are associated with an abnormality in the function of the sebaceous glands, including:

Acne (pimples).

Sebaceous cysts - closed bags or cysts on the surface of the skin.

Hyperplasia - enlarged sebaceous glands that produce yellow, shiny bumps on the face.

Sebaceous adenoma - slow growth of tumors (benign and not cancerous) usually occurs in pink, yellow or flesh-colored papules or nodules.

The sebaceous gland carcinoma - an aggressive skin tumor (cancer) and infrequent.

If a break occurs, doctors recommend to be treated quickly to avoid the risk of developing severe acne. There is also a danger that severe acne can lead to treating visible scars on the skin.

What are the causes of pimples?

The sebaceous glands that produce sebum, found inside the pores of our skin. The outer layer of our skin is to be cast continuously.

Sometimes the dead skin cells left behind and are then glued together by the sticky sebum, which causes a blockage in the pore.

The blockage of the pores is more likely to occur during puberty (the process of physical changes by which the body of a child becomes an adult body capable of reproduction). More sebum is produced by the sebaceous glands - the pore is blocked, it builds up behind the obstruction.

This accumulation of sebum and blocked a bacteria, including Propionibacterium acnes, the slow growth of bacteria is associated with acne. Propionibacterium acnes is generally harmless to the skin - However, when conditions are favorable, can reproduce more rapidly and become a problem. The bacteria feeds on sebum and produce a substance that provokes an immune response, leading to inflammation of the skin and stains.

The skin of people who are prone to acne are especially sensitive to normal levels of testosterone - a hormone that is found naturally in both men and women. In these people of testosterone can cause the sebaceous glands produce too much sebum, so the congestion of dead skin cells is more likely, increasing the likelihood of blockage of the pores, etc.

You can not get the buttons from another person, are not infectious.

There is no convincing scientific evidence that acne is caused by food.

Having pimples or acne can be hereditary.

Signs and symptoms of Acne - Types of acne

Whiteheads - also known as a closed comedo. These are very small, and remain under the skin papules show a small flesh-colored.

Papules - are small lumps, rounded sound from the skin. Potholes are often pink.

Pustules - these buttons are filled with pus. They are clearly visible on the surface of the skin. The base is red and has pus on top.

Nodules - these are morphologically similar (similar structure) is a lump, but larger. They can be painful and are embedded deep into the skin.

Cysts - are clearly visible on the surface of the skin. They are filled with pus and often painful. Cysts often cause scarring.

How common are pimples (acne)?

A sample survey of young people in New Zealand is the acne is present in 91% of boys and 79% of girls.

A sample study of adolescents in Portugal found that the average prevalence of acne (both sexes) was 82%.

30% of teenagers with acne need medical treatment because of its severity.

General practitioners (GPs, primary care physicians) in the United Kingdom reported that 3.1% of 13 to 25 years, visited the patients complain of acne.
