Acne Prone Skin Causes

Acne is a condition of the skin that is characterized by inflamed pimples, which are called pustules, and plugged pores, which are known as whiteheads and blackheads. There can also be deeper lumps, which are called nodules. Acne occurs when an oily substance called sebum is blocked from reaching the surface of the skin through pores which are the openings of follicles. Sebum is produced by glands called sebaceous glands that reside near the surface of the skin. When the sebum is blocked, bacteria can multiply in the blocked follicle and attract white blood cells. The walls of the blocked follicle can break down, pimples and lesions form, resulting in acne. There are several factors that can increase the risk for having skin that is prone to acne.

Hormones

An increase in the levels of hormones called androgens can increase the risk of developing acne. Androgens are known as male sex hormones, although both males and females have these hormones. During puberty, the levels of these hormones increase in both boys and girls. The increase in hormones causes the sebaceous glands to enlarge and to produce more of the substance called sebum. This can lead to skin that is more prone to acne. Other changes in the levels of hormones can lead to skin that is more prone to acne. Hormone level changes can occur during pregnancy. Starting or ending the use of birth control pills also leads to changes in hormone levels. Some medical treatments that use hormones can change the levels in the body.

Genetics

According to the National Institute of Arthritis and Musculoskeletal and Skin Diseases, genetics plays a role in susceptibility to acne. This tendency for skin to be prone to acne can be inherited. Boys who are in school and have acne tend to have family histories of acne.

Other Factors

Some medications, such as lithium, can increase the risk of acne. Cosmetics that are greasy make the skin more prone to acne by increasing the risk of having the follicles blocked. This would cause the sebum to be unable to reach the surface and result in pimples. Greasy conditions, such as the environment near deep fryers, can increase the risk of acne.
