Pimples can be a real pain in the butt. They don’t only make you feel self-conscious about yourself, but they also affect your confidence. They’re caused by bacteria on your skin and blocked hair follicles.

How do pimples form?

Pimples are caused by bacteria on your skin and blocked hair follicles. They start as whiteheads, blackheads or papules (reddish bumps). When the pore is filled with oil and dead skin cells, it becomes clogged and infected by bacteria. The body sends white blood cells to fight the infection and inflammation occurs.

Are pimples contagious

Pimples aren’t contagious, and they’re not caused by a virus or bacteria. They’re also not caused by fungus, parasites or worms.

  • Pimples are often caused by oil build-up in clogged pores,
  • Stress can cause skin conditions like acne to flare up—even if you don’t have acne before the stress starts!

Bacteria on your skin

The first way acne can occur is through bacteria on your skin. If you have more bacteria than normal on your face, the oil glands produce more oil to try and fight off the bacteria. This increased production of oil causes clogged pores, which leads to pimples.

Bacteria that live on your skin can cause acne breakouts in different areas of your body including:

  • Face – Usually located around the nose and mouth area; this type of acne is also called blackheads or whiteheads (open comedones).
  • Back – Also known as backne or bacne, this type of acne occurs due to excessive sweating caused by friction between clothing and skin that has been contaminated with bacteria from sweat.

Acne can also be caused by:

  • Infection – If a wound gets infected with bacteria then it may lead to an infection called folliculitis (inflammation/bacterial infection under a hair follicle). This condition often causes redness around the affected area along with pus filled bumps which resemble pimples but aren’t actually related at all!

Blocked hair follicles

Acne is caused by a blocked hair follicle. A hair follicle is the tiny hole in your skin from which your hair grows. When this pore becomes blocked, it can cause bacteria to grow in it and that causes redness and swelling and pimples!

No, acne isn’t contagious—it’s not something you catch from touching someone else who has it or sharing towels with them. And yes, dirt can make some pimples worse but it doesn’t cause them directly. If you’re wondering how do pimples form? The answer lies in the fact that zits are actually small clogs in your pores that contain bacteria that feed off oil produced by sebaceous glands (oil glands). Bacteria causes inflammation, which inflames surrounding tissue and makes you feel like hell until you pop your pimple open because who wants to deal with an infected blackhead?!

Can be an inherited condition

Acne can be influenced by a number of factors, including hormonal imbalance, genetics and skin type. In some cases, acne may be an inherited condition.

Acne is not a disease and therefore cannot be caught from another person like the common cold or chicken pox. Acne isn’t caused by poor hygiene either; in fact the opposite is often true—that people with acne often wash their faces too much!

While many things can contribute to an outbreak (including stress hormones), there are ways you can minimize this embarrassing problem on your own:

Can develop in adults

You may have thought, “only teenagers get acne. I’m in my 20s. I don’t need to worry about that.” But there’s actually no age limit for acne. Acne can develop at any time, including as an adult or even when you’re a child!

Can develop in children

Pimples are a common condition that affect many children, and they can also occur in adults. The following information will help you understand why pimples develop and what you can do to prevent or treat them.

Pimples are not caused by poor hygiene, diet or stress.

Can form under the skin

You can get pimples on your face, back, chest, arms and legs.

They aren’t necessarily the same as acne.

If you have an open wound on your skin then it’s possible for bacteria to get into that wound and cause an infection which causes pus (pimples) to form underneath the skin.

Causes blackheads and whiteheads

If you’re looking for signs of a blackhead or whitehead, it’s usually easy to spot. Blackheads are open pore follicles that have become filled with debris, allowing oxygen to oxidize the skin pigment melanin. The resulting black color is what gives them their name. Whiteheads occur when a clogged follicle remains closed off from the air and has no way of oxidizing the melanin in its contents (which typically appear white). Both types can be found all over your body—although they’re more likely to crop up on your face than elsewhere—and both are generally pretty easy to clear up by themselves.

Causes pimples on your face

Pimples form when a pore fills with dead skin cells and becomes clogged. If you have oily skin, your pores are filled with more sebum than others’—the oil that keeps your skin looking moisturized. A pore’s natural tendency is to protect itself from bacteria by trapping particles like grains of sand or other impurities in the dirt outside it. When these blockages occur, sebum (oil) builds up inside the pore and causes an infection called acne.

The most common trigger for pimples is hormones in your body called androgens, which can be stimulated by many factors including stress and dieting too quickly. Acne is also associated with having a family history of it; if your parents had breakouts as teens or adults, you may have inherited genes that make it difficult for you to control how much oil gets produced on your skin surface.

Causes strep throat

As the name suggests, strep throat is caused by a bacterial infection and the symptoms can be quite unpleasant. A person with strep throat will have a sore throat and swollen lymph nodes in their neck. They’ll also experience fever, headache and fatigue.

Strep throat is caused by group A Streptococcus bacteria which is spread through direct contact with an infected person or through sneezes or coughs from other people who aren’t exhibiting symptoms yet – so if you have someone in your house who has strep throat but doesn’t know it yet, you can get it too!

Causes tiny red bumps on your skin

Tiny red bumps on your skin can be caused by many different things. One of the most common causes is small blood vessels in the skin. Tiny red bumps on your skin can result from a variety of factors, including acne and other conditions like rosacea and perioral dermatitis.

Caused by infection or swelling of hair follicles in the skin. specifically, pimples form inside the follicles, which are small sacs beneath your skin surface. these follicles contain a fine hair and sebaceous glands, which are tiny sebum-producing glands in your skin. the sebum carries dead skin cells through the follicle to the surface of the skin. a plug that is formed by oil and dead skin cells blocks the follicle. bacteria grow in this plugged follicle, giving you a red bump called a pimple.

Pimples form when the hair follicle becomes blocked, which prevents sebum from reaching the surface of your skin.

A number of things can cause this blockage, including:

  • A hair follicle may become clogged with dead skin cells and oil that builds up over time. This creates an environment for bacteria to grow, leading to inflammation and redness of the skin around it (pimple).
  • You may have small sweat glands in your skin that are connected to hair follicles, which can also become clogged with oils and dead skin cells that build up over time. This building up of oils causes pimples to develop along with swelling of surrounding tissue (redness).


Pimples can be a pain, but they’re also a normal part of life. The best thing you can do is keep your skin clean and try to not pick at the pimples so that they don’t get worse.
