Acne is caused by hormones, oily skin, and bacteria which can result in inflammation of hair follicles, the pores in the skin where your hair grows. Acne could be characterized by different types of abnormal growths. They can all vary in size and how severe they look, some types of acne go deeper into the skin than others do for example, blackheads are open comedone, whiteheads are closed comedones. The pimple is an inflamed closed comedone and are usually raised solid bumps. On the surface of the bumps they contain the pus. If the pimple is deeper, more firm and it contains pus it is called nodules. Lastly cysts are large pockets containing pus. Sometimes even larger, deeper pockets containing pus are called abscesses. Both the cysts and abscesses are pus-filled pockets, but the abscesses are sometimes larger and deeper. The sebaceous glands which secrete an oily substance, sebum, lie in the middle layer of skin, these glands are attached to the hair follicle. Sebum also with the dead skin cells, passes up from the sebaceous gland and hair follicle and then it goes out to the surface of the skin through the pores creating a type of pimple.
Hair Follicle Anatomy Acne can result when a collection of dried sebum, dead skin cells, and or bacteria gets clogged up in the hair follicles which then blocks the sebum from leaving through the pores. A blackhead then develops if the blockage is incomplete. A whitehead can then develops if the blockage is complete. The most common thing that triggers acne is puberty. Acne occurs only mainly during puberty, which is when the sebaceous glands are stimulated by the increasing hormone levels, especially the testosterone, resulting in excessive sebum production. When a person is in their early to mid 20s, hormone levels usually have decreased enough that acne lessens or disappears. However, up to 40% of women can get acne into their 40’s. Other conditions that involve hormonal changes can affect the occurrence of acne like being pregnant, or on your menstrual cycle, curtain drugs, also some products that you put on your face and wearing too tight of clothes. Lastly, when it is humid you create a lot of pimples and also when you sweat. Acne can occur with each menstrual period in a young women and may clear up or it can worsen during your pregnancy. Polycystic ovary syndrome is a hormone disorder that can disrupt the menstrual cycle and can trigger the acne making it worse. The use of certain drugs, particularly corticosteroids and anabolic steroids, can worsen acne or cause acne breakouts. There are many cosmetics, cleansers, and lotions that may worsen acne by clogging the pores in your skin. Acne
