The oil gland releases sebum (oil), which travels up the hair, out of the pore, and onto your skin.our skin has tiny holes called pores that that can become blocked by oil, bacteria, and dirt.
Causes of pimples / zits. The sebaceous glands, which produce sebum, exist inside the pores of our skin. The outer layers of our skin are being shed continuously. Sometimes, dead skin cells are left behind and get stuck together by the sticky sebum, causing a blockage in the pore. Pimples are also known as spots or zits. Pimples occur when the sebaceous glands, which are located at the base of hair follicles, become overactive. The most vulnerable parts of the body are the face, back, chest and shoulders. Acne occurs when the pores on your skin become blocked with oil, dead skin, or bacteria. Each pore on your skin is the opening to a follicle. The follicle is made up of a hair and a sebaceous (oil) gland. The oil gland releases sebum (oil), which travels up the hair, out of the pore, and onto your skin. Your skin has tiny holes called pores that that can become blocked by oil, bacteria, and dirt. When this occurs, you may develop a pimple or “zit.” If your skin is repeatedly affected by this condition, you may have acne. These areas of skin have the most oil (sebaceous) glands. Acne occurs when hair follicles become plugged with oil and dead skin cells. Hair follicles are connected to oil glands. These glands secrete an oily substance (sebum) to lubricate your hair and skin. 1 Acne isn't caused by dirt. 2  In fact, scrubbing the skin too hard or cleansing with harsh soaps or chemicals irritates the skin and can make acne worse. 3  Though it does help to gently remove oil, dead skin and other substances. 4  Cosmetics. No one factor causes acne. Acne occurs when sebaceous (oil) glands attached to the hair follicles are stimulated at the time of puberty by circulating male hormones. Sebum (oil) is a natural substance that lubricates and protects the skin. 1 Dirt: Blackheads are oxidized oil, not dirt. 2  Sweat does not cause acne and is produced by entirely separate glands in the skin. 3  On the other hand, excessive washing can dry and irritate the skin. 4  Stress: Some people get so upset by their pimples that they pick at them and make them last longer What Causes Pimples & Acne. To control blemishes effectively, it’s important to understand how spots form and what causes it. The most important thing to remember about pimples is: It's not your fault. Contrary to popular belief, zits are not caused by external factors such as what you eat, how often you wash your face or exercise.  Causes of acne. Nobody is completely sure what causes acne. Experts believe the primary cause is a rise in androgen levels-androgen is a type of hormone. Androgen levels rise when a human becomes an adolescent. Rising androgen levels make the oil glands under your skin grow; the enlarged gland produces more oil.  Acne-Cause. There are different types of acne. The most common acne is the type that develops during the teen years. Puberty causes hormone levels to rise, especially testosterone. These changing hormones cause skin glands to start making more oil (sebum). Oil releases from the pores to protect the skin and keep it moist. Pimples are small skin lesions or inflammations of the skin-they are sebaceous glands (oil glands) which are infected with bacteria, swell up, and then fill up with pus. Pimples are also known as spots or zits. Pimples occur when the sebaceous glands, which are located at the base of hair follicles, become overactive. The most vulnerable parts of the body are the face, back, chest and shoulders. Pimples are palpable signs of acne, especially when a breakout occur
