When your glands are producing just the right amount of sebum, your skin looks healthy, but not shiny. Too little sebum can lead to dry, cracking skin. Too much sebum in a follicle can cause a hardened plug to form, which can then lead to various forms of acne.
What Do They Look Like? Usually you can spot a blackhead easy enough, sebum plugs are a little trickier but if you grab a magnifying glass you can see them no problem. You will notice that although they may look like little black dots from a distance, they are actually more of a white or yellow color.
Enlarged sebaceous glands cause sebaceous hyperplasia. These glands become enlarged when the cells that form the gland, known as sebocytes, overgrow and overproduce sebum. This leads to a buildup of oil.
Keratin plugs don't usually require medical treatment. However, it's understandable to want to get rid of them for aesthetic reasons, especially if they're located in a visible area of your body. First, it's important to never pick at, scratch, or attempt to pop keratin plugs. Doing so may only cause irritation.
Nazarian recommends exfoliating with topical medications, such as glycolic acid, retinoids, and salicylic acid, to break down the plugs and dissolve them. Eventually, your pores will refill, so like a game of Whac-a-Mole, those sebaceous filaments will pop right back up, requiring you to be consistent in your routine.
Nodules are a type of hard pimple that can be large and painful. They form when an infected skin pore or follicle is located deep below the skin surface. Cysts are found deep below the skin when a pus-filled membrane forms around the infection. They are likely to scar.
Use gentle exfoliants to remove dead skin cells trapped along with keratin. You can try gentle acids like topicals or peels that have lactic, salicylic or glycolic acid. If exfoliation doesn't work, a dermatologist may suggest stronger prescription creams to help dissolve them.
Recap. Scalp buildup involves sebum (natural oils), hair products, sweat, and dead cells. It can cause scalp problems like dandruff and itching as well as acne and other skin conditions if it's not treated.
The white stuff that comes out of your pores like thin strings when you squeeze your nose is called a sebaceous filament. It's mostly made up of sebum (oil that your skin produces) and dead skin cells. This substance typically collects in pores around your nose and chin.
Pimple pus is made from sebum (oil) that gets trapped in your pores, along with a combination of dead skin cells, debris (such as makeup), and bacteria. When you have inflammatory acne lesions (such as pustules, papules, nodules, and cysts), your immune system activates in this area, resulting in noticeable pus.
Though you may be tempted to squeeze or otherwise get rid of a sebaceous filament, it's best to leave them alone. Squeezing or picking at sebaceous filaments risks scarring and spreading any bacteria that may be in or around the pore to other parts of your face, causing a breakout.
Bumps on your scalp can be a symptom of a few different health conditions. Most of the time, these bumps indicate an allergic reaction or clogged hair follicles, neither of which is usually a cause for concern.
As lesions age, dilation of follicular openings occurs with a keratinous plug, termed follicular plugging or patulous follicles (see the image below). Resolution of the active lesion results in atrophy and scarring.
Sebum plugs can create the look of oily hair and can create discomfort and itching on the scalp. Quite literally, they are plugs that clog up the pores of your scalp, which can create problems that range from mild irritation to hair thinning.
Common Causes
It's hypothesized that keratin may create a plug within the pilosebaceous unit, or what is commonly called the pore or hair follicle. This plug of keratin leads to irritation of the follicle. The follicle then becomes inflamed and leads to the development of a painful lump called a nodule.
Another drainage option to combat sebaceous cysts include fine-needle aspiration. A thin needle is inserted into the cyst to drain the liquid. This method is often used for cysts on the breast. While these are both a quick and painless fix, the cysts are likely to continue to occur unless complete removal is performed.
Cysts can appear anywhere on your body and may look and feel like a small, hard pea. The most common causes of cyst formation include clogged oil glands, infections, and a growth that develops around a foreign body such as an earring or navel ring.
To reduce the chance of scarring, it is essential not to attempt to pop acne nodules. Trying to squeeze them will only cause further inflammation and may cause scarring.
When you pull out your hair "by the root," you may observe a transparent swelling called the "bulb." The area above the bulb usually seen on a plucked hair is the root sheath, the growing area of a hair.
Also known as nits, lice eggs are hard to see and often confused for dandruff or droplets of hair spray. They are small white specks and can be found at the base of the hair shaft.
Bacterial folliculitis. This common type is marked by itchy, white, pus-filled bumps. It occurs when hair follicles become infected with bacteria, usually Staphylococcus aureus (staph). Staph bacteria live on the skin all the time.
extreme stress. poor skin care habits (such as not washing your face twice a day, or wearing oil-based makeup) dry skin (ironically, having dry skin can make pores more noticeable due to an increase in sebum production and accumulation of dead skin cells on the surface of your skin)
Pus is a thick mixture of white blood cells and bacteria. Papules are larger, hard pink or red bumps that can feel sore when you touch them. Pustules are red, inflamed bumps that are filled with pus. Nodules are hard lumps that form deep inside the skin.
Keratosis pilaris develops when keratin forms a scaly plug that blocks the opening of the hair follicle. Usually plugs form in many hair follicles, causing patches of rough, bumpy skin.
