Pores And The Mystery Of The Cheesy Odor

why do pores discharge smell like cheese

Pores can become clogged with excess oil and dead skin cells, trapping bacteria and leading to acne. While mild acne generally does not produce a strong smell, moderate to severe acne with pus discharge may have a more pungent odour. The presence of bacteria, the intensity of the breakout, and personal hygiene practices all contribute to the distinctive scent. Acne that smells like cheese could be caused by an epidermoid cyst, a noncancerous bump under the skin, which can develop due to a blocked hair follicle. The main symptom of an epidermoid cyst is a lump that can become painful if inflamed or infected. The cyst contains a soft, cheese-like substance known as keratin, which has an unpleasant odour.

Poor hygiene can cause bacteria to grow, leading to a cheesy smell

Maintaining proper hygiene is essential to prevent clogged hair follicles and pores. The American Academy of Dermatology (AAD) recommends a face-cleaning routine that includes washing your face twice a day and after sweating. It is important not to wash your face too frequently, as this can irritate the skin. Instead of scrubbing, gently wash your skin and use appropriate skincare products and cosmetics labelled "oil-free", "won't clog pores", "noncomedogenic", and "nonacnegenic".

Exfoliation is another important step in maintaining good hygiene and preventing clogged pores. It helps remove dead skin cells that can build up and block pores. Additionally, deep-cleaning masks can be used to draw out plugs from pores. Consulting a dermatologist is recommended when making significant changes to your skincare routine or if you have questions about cleaning your pores. They can provide guidance on the types of cleansers and other products suitable for your skin type.

By following these hygiene practices, you can help prevent clogged pores and reduce the risk of bacterial growth, which can contribute to the cheesy smell associated with pore discharge. However, it is important to note that mild acne or clogged pores generally do not produce a strong odour. The severity of acne and the presence of certain types of bacteria are also factors that influence the smell.

Anaerobic bacteria produce sulfur compounds, resulting in a pungent smell

The human skin is host to a variety of bacteria, some of which are harmful and can cause acne. When pores are clogged with sebum and dead skin cells, bacteria can contribute to the formation of odour and acne.

Anaerobic bacteria, which do not require oxygen to survive, can cause a foul smell in acne discharge. These bacteria produce their own sulfur compounds as they grow, and these sulfur-containing compounds can cause a pungent smell of garlic or onions when a pimple is popped. The smell of sulfur is often likened to that of rotten eggs or onions.

The severity of acne can also contribute to its odour. Moderate to severe acne with pus discharge is more likely to have a strong smell. Poor hygiene can also increase the likelihood of bacterial infections, leading to more severe infections with stronger odours.

In some cases, the foul-smelling discharge from pores may be related to an epidermoid cyst, a noncancerous bump under the skin. These cysts contain a thick, yellow substance made of the protein keratin, which has a cheese-like texture and an unpleasant smell. While epidermoid cysts typically do not require treatment, they can occasionally become inflamed or infected and may require medical attention.

Epidermoid cysts, a type of noncancerous bump, can cause a cheese-like odour

The presence of bacteria, the intensity of an acne breakout, and personal hygiene practices can contribute to the distinctive scent of acne. Various types of bacteria can infest the skin, resulting in clogged pores and acne. Both aerobic bacteria (bacteria that require oxygen to grow) and anaerobic bacteria may cause a foul smell in acne discharge. The more severe the acne, the more likely it is to have a strong odour.

If your acne has a discharge that smells like cheese, you most likely have an epidermoid cyst, a noncancerous bump under your skin. An epidermoid cyst is a blocked hair follicle that develops when dead skin cells accumulate deep in the skin and don't slough off as they should. An injury or irritant may also cause epidermoid cysts to form. These cysts typically consist of a thick, yellow substance made of the protein keratin that has a cottage cheese-like texture and an unpleasant smell.

Epidermoid cysts are typically painless and harmless and do not usually require treatment. However, they can occasionally become inflamed or infected and, rarely, even develop into skin cancer. If the cyst turns red, swollen, or painful, it is important to visit a dermatologist, who may decide to treat the cyst with anti-inflammatory injections, drain it, or remove it completely.

To prevent clogged pores and acne, the American Academy of Dermatology (AAD) advises maintaining proper hygiene and a face-cleaning routine. This includes washing the face twice a day and after sweating, avoiding washing more frequently to prevent skin irritation, and gently washing the skin without scrubbing. It is also important to use appropriate skincare products and cosmetics that are labelled as "oil-free", "won't clog pores", "noncomedogenic", and "nonacnegenic". Additionally, deep-cleaning the pores with a mask, exfoliating to remove dead skin cells, and using topical treatments such as salicylic acid and glycolic acid ointments can help keep the skin clear and reduce the risk of developing epidermoid cysts.

Acne conglobata, a severe form of acne, may result in a rotten egg-like smell

Acne is an inflammatory skin disorder that occurs when oil glands become clogged with excess oil and dead skin cells, trapping bacteria in the pores. While mild acne generally does not produce a strong smell, moderate to severe acne with pus discharge may have a bad smell. The severity of the odour is also influenced by hygiene practices, as poor hygiene increases the likelihood of contracting secondary bacterial infections, resulting in acne pus with a stronger odour.

Acne conglobata is a rare and severe form of nodulocystic acne that develops when painful, large cysts connect deep beneath the skin. It is characterised by tender, inflamed, and disfiguring double or triple interconnecting comedones, cysts, inflammatory nodules, and deep burrowing abscesses. This type of acne commonly affects the face, shoulders, back, chest, upper arms, buttocks, and thighs.

The first sign of acne conglobata is the presence of multiple inflamed nodules filled with pus that may have a foul odour resembling rotten eggs. This distinctive smell is attributed to the anaerobic bacteria that thrive in the acne lesions. As these bacteria produce their own sulfur compounds, the pus they feed on can emit a pungent smell reminiscent of garlic or onions when the acne is popped.

To address acne conglobata, it is recommended to consult a dermatologist for prescription-strength treatments. Retinoids, such as isotretinoin, are often the treatment of choice, sometimes combined with oral prednisone or steroids. Antibiotics may also be prescribed to help manage the infection and reduce the severity of symptoms. Maintaining proper skin hygiene and a suitable skincare routine is crucial to prevent further bacterial growth and infection.

A sebaceous filament, made of sebum and dead skin cells, can cause clogged pores

The white substance that comes out of your pores when you squeeze them is called a sebaceous filament. It is made up of sebum (an oily substance produced by the skin's sebaceous glands) and dead skin cells. Sebaceous filaments are a normal part of the skin and help to transport sebum to the skin's surface, keeping it lubricated and hydrated.

When the body produces too much sebum, sebaceous filaments can become blocked, leading to clogged pores. Clogged pores can also be caused by a build-up of dead skin cells, bacteria, and excess oil. This can result in acne, which can have a strong smell if it becomes infected by bacteria.

While sebaceous filaments themselves do not block pores, they can become more noticeable when the body overproduces sebum. This can give the appearance of enlarged, darkened pores. Poor skin maintenance, such as excessive sun exposure or over-washing, can also cause the sebaceous glands to produce more sebum, leading to more apparent sebaceous filaments.

To prevent clogged pores, it is important to maintain proper hygiene and a suitable skincare routine. This includes cleansing, exfoliating, and moisturising the skin, as well as using appropriate skincare products and cosmetics that are labelled "non-comedogenic" or "nonacnegenic". It is recommended to consult a dermatologist for specific advice and treatment options.

While sebaceous filaments can be manually squeezed out, it is generally not advised as it can irritate the skin and the pore will fill up with sebum again within 30 days. Instead, there are treatments available, such as salicylic acid and retinoids, that can help prevent clogged pores and reduce their appearance.
