Causes
The human skin has pores that are connected to the sebaceous glands under the skin. Vesicles connect glands to pores. Hair follicles are small sacs that produce and secrete fluids.

The glands produce an oily liquid called sebum. Sebum transports dead skin cells through the hair follicles to the surface of the skin.A small hair grows from the skin through the hair follicle.

Pimples grow when these hair follicles are blocked and oil builds up under the skin.

Skin cells, sebum and hair can aggregate into a plug. This plug becomes infected with bacteria and causes swelling. The pimple begins to grow when the stopper begins to crack.

Propionibacterium acnes (P. acnes) is the name of the bacterium that lives on the skin and contributes to the formation of pimples.

Research suggests that the severity and frequency of acne depends on the bacterial strain. Not all acne bacteria cause pimples. One variety helps keep blemishes free.

Hormonal Factors
Acne is caused by a number of factors, but the main cause is thought to be an increase in androgen levels.

Androgen is a type of hormone whose levels increase with the onset of puberty. In women, it is converted to estrogen.

Increased androgen levels cause the sebum glands under the skin to grow. The enlarged gland produces more sebum.Excess oil can break down the cell walls in your pores, allowing bacteria to grow.
