Pimples most commonly form on the face, neck, back, shoulders, and chest. Acne is the skin condition responsible for pimples. Most commonly, pimples are associated with whiteheads and blackheads. Foods like chocolate, pizza, and soda have been blamed for causing pimples.
Caring for your skin is a much better way to prevent and treat acne. The most common type of acne is called acne vulgaris. This very common skin condition affects 70 to 87 percent of teenagers and up to 50 million Americans.
It can cause acne your entire life. Acne vulgaris manifests as various types of skin blemishes, including whiteheads, blackheads, papules, and pustules. Whiteheads occur when skin cells, oil, and bacteria combine to create a white tip of oil-skin mixture. A whitehead looks like a small pimple, but the area around it will not be inflamed and red. Blackheads are also not inflamed. They form when the plug that clogs the pore sits at the top surface of the skin.
Blackheads are not dirt stuck in your pores. A pimple is a clogged pore that has become infected. The infection makes a white pus-filled tip on top of the affected pore. The area around the infected pore can become inflamed, red, and sensitive. Your skin is covered in millions of tiny little wells, or pores, that sit at your hair follicles. Pores connect the surface of your skin to an underlying gland called the sebaceous gland.
This gland produces an oily substance called sebum. Sebum is released continually, in small amounts, into the hair follicles and skin. Dead skin cells are also carried up with the sebum so they can be washed away. Occasionally, the sebaceous gland produces too much sebum. Measure ad performance. Select basic ads.

All acne is a disorder of the pilosebaceous unit , which is made of a hair follicle, sebaceous glands, and a hair. These units are found everywhere on the body except on the palms of the hands, the soles of the feet, the top of the feet, and the lower lip.
The number of pilosebaceous units is greatest on the face, upper neck, and chest. Sebaceous glands produce a substance called sebum, which is responsible for keeping the skin and hair moisturized. During adolescence, sebaceous glands enlarge and produce more sebum under the influence of hormones called androgens. After about age 20, sebum production begins to decrease. Sebum produced by the sebaceous gland combines with cells being sloughed off within the hair follicle and fills up the hair follicle.
When the follicle is full, the sebum spreads over the skin surface, giving it an oily appearance. When this process works correctly, the skin is moisturized and remains healthy. When this process does not work correctly, the skin can become either overly dry or overly oily, the latter of which raises the risk for acne. After the age of 25 years, it affects 3 percent of men and 12 percent of women. Whiteheads : Also known as a closed comedo, these are small pimples that remain under the skin.
They appear as a small, flesh-colored papule. Blackheads : Also known as an open comedo, these are clearly visible on the surface of the skin. Some people mistakenly believe they are caused by dirt, because of their color, and scrub their faces vigorously. Scrubbing does not help. It may irritate the skin and cause other problems. Papules : These are small, solid, rounded bumps that rise from the skin.
They are often pink. Pustules : These are pimples full of pus. They are clearly visible on the surface of the skin. The base is red and the pus is on the top. Nodules : These have a similar structure to papules, but they are larger. They can be painful and are embedded deep in the skin. Cysts : These are clearly visible on the surface of the skin. They are filled with pus and are usually painful. Cysts commonly cause scars. Pimples happen when pores become clogged with sebum and dead skin.
Sometimes this leads to infection and inflammation. Why they affect some people more than others is largely unknown. The sebaceous glands are tiny skin glands that secrete sebum, a waxy or oily substance that lubricates the skin and hair.
Sebaceous glands are found inside the pores of our skin, all over the body, except the palms of the hands and soles of the feet. There are more sebaceous glands on the face and scalp than elsewhere.
As the glands produce sebum inside the pores, new skin cells are constantly growing, and the outer layers of skin are being shed. Sometimes, dead skin cells are not shed. They remain in the pores and get stuck together by the sticky sebum, causing a blockage in the pore.
Pore blockage is more likely to occur during puberty, as the sebaceous glands produce more sebum at this time.
