Blackhead vs Sebaceous Filament – How To Tell The Difference?

Blackheads and sebaceous filaments can look very similar, but they are actually two very different skin issues.

If you’ve been struggling with persistent spots on your face, you need to understand the difference between these two so that you can treat them correctly.

So, let’s take a look at a comparison between blackhead vs sebaceous filament, so you can tell the difference.

Blackhead vs Sebaceous Filament - How To Tell The Difference?

What Is A Blackhead & What Do Blackheads Look Like?

A blackhead, scientifically known as an open comedone, is essentially an opening or enlarged pore in your skin that’s become clogged with dead skin cells and sebum – an oily secretion produced by your body’s sebaceous glands.

The top of this clog oxidizes upon exposure to air, which leads to its characteristic dark hue. Contrary to common misconceptions, it isn’t dirt or grime that causes the black color but rather oxidation.

Blackheads can appear almost anywhere on your body, but they’re most commonly found in areas with high concentrations of oil-producing glands such as the face – particularly around the nose – and back.

They’re usually round in shape with a slightly raised texture that may feel rough when touched.

Understanding the difference between blackheads vs sebaceous filaments is essential for proper skin care regimes, and you can always book an appointment with a dermatologist for more help in differentiating between the two – and difference between sebaceous filaments and blackheads.

While both involve pores filled with excess oils and dead skin cells, unlike blackheads, sebaceous filaments aren’t considered a form of acne since they don’t lead to inflammation or infection unless blocked by external factors leading to bacterial buildup.

What Is A Sebaceous Filament & What do Sebaceous Filaments Look Like?

Sebaceous filaments are a normal part of the skin’s anatomy, aiding in the distribution of sebum (a natural oil) across your skin to keep it supple and moisturized.

To understand what a sebaceous filament is better, here’s some key information:

  • They’re primarily found in areas with larger oil glands such as the nose or forehead.
  • Unlike blackheads, they’re not a type of acne nor are they caused by dirt or neglect.
  • They naturally refill within 30 days after being emptied.
  •  They can become more visible due to large pores or excessive sebum production.

Sebaceous filaments look like small pin-sized dots on the surface of your skin. In comparison to blackheads, which are dark due to oxidation, these structures maintain their pale color because they don’t oxidize.

Trying to remove them entirely can damage your skin since it disrupts its natural moisture balance.

Overzealously squeezing them out can lead to inflamed pores and potentially cause scarring.

Instead, maintaining regular skincare routines using non-comedogenic products helps control excessive oiliness and minimizes their appearance.

Can You Squeeze Sebaceous Filaments and Blackheads?

Handling sebaceous filaments and similar skin structures too roughly can lead to more harm than good, and won’t remove blackheads entirely.

When you squeeze blackheads or sebaceous filaments, you risk causing inflammation, scarring, and even infection.

To better understand why it’s best not to pick at these skin issues, consider the following, when touching your skin’s surface:

Sebaceous Filaments Blackheads
Natural part of the skin’s oil production system. Squeezing them can disrupt this process and possibly damage hair follicles. Blocked pores filled with excess oil and dead skin cells. Squeezing them pushes bacteria deeper into the pore, which could cause an inflammatory response or infection.
Usually return within 30 days after removal due to their role in natural oil regulation. So, even if you squeeze them out, they will likely reappear quickly May not return as quickly but squeezing increases likelihood of scarring and hyperpigmentation.

Both sebaceous filaments and blackheads are normal components of our skin’s structure.

If they’re causing concern due to excessive visibility or other aesthetic reasons, there are safer ways to deal with them than applying pressure with your fingers.

Proper skincare routine including gentle cleansing, regular exfoliation using salicylic acid (which can penetrate oil-filled pores), occasional use of clay masks for absorbing excess oils can help manage these issues without risking harm by attempting to manually extract them yourself.

When you exfoliate the skin, you’re able to keep your skin clear with ingredients like beta hydroxy acids, glycolic acid – AHAs and BHAs, as part of your skin care routine.

Blackhead Vs Sebaceous Filaments – Understanding the Difference

Understanding the difference between blackheads vs sebaceous filaments can help in managing them efficiently.

  • Formation: Blackheads, formerly known as open comedones, are formed when the opening of a pore becomes clogged with dead skin cells and sebum. This plug oxidizes upon contact with air, turning it a distinctive black color – hence the name ‘blackhead’.

Sebaceous filaments, on the other hand, are naturally occurring part of your skin’s oil (sebum) production system. They line the inside of pores to help guide sebum towards the surface of your skin.

  • Appearance: The difference in their appearance is starkly evident as well. Blackheads typically appear as small black or dark gray spots on your skin surface, while sebaceous filaments are often less noticeable unless under close inspection – appearing as tiny hair-like strands or pin-sized dots usually in a whitish or yellowish color.
  • Location: Though both can occur anywhere, there are pores; blackheads are more commonly found in areas like the nose and forehead (T-zone), whereas you’ll find sebaceous filaments all over the face, especially around the nose and cheeks.

What Causes Appearance of Sebaceous Filaments and Blackheads?

Two of the most common culprits are sebaceous filaments and blackheads. Understanding the difference between blackheads and sebaceous filaments is key to managing them effectively.

Sebaceous filaments are naturally occurring, thin, hair-like structures that channel the flow of sebum along the lining of your pores.

They’re most commonly seen in areas with a high concentration of sebaceous glands like your nose or forehead.

Their appearance is due to an overproduction of oil (sebum) by these glands, which can make them more noticeable.

On the other hand, blackheads form when your pore becomes clogged with excess oil and dead skin cells.

A process known as oxidation causes this mix to darken upon exposure to air, hence their characteristic dark color.

Unlike sebaceous filaments, they aren’t a natural part of your skin’s functioning but rather a sign of acne vulgaris.

So, what causes the appearance of sebaceous filaments and blackheads?

Both can be influenced by various factors including hormonal fluctuations, diet, stress levels, improper skincare routines, or products that trigger excessive oil production or don’t effectively remove dead skin cells.

How To Remove Sebaceous Filaments?

How To Remove Sebaceous Filaments?

To treat sebaceous filaments, follow a consistent regimen geared towards managing excessive oil production. Here are some steps to consider:

Regular Cleansing

  1. Use an oil-based cleanser to dissolve excess sebum from your pores.
  2. Opt for a salicylic acid cleanser as it penetrates deep into the pores and dissolves debris.


  1. Incorporate chemical exfoliants (like BHAs or AHA’s) into your routine. These work by loosening the bonds between skin cells, allowing for easier removal of dead skin and sebum.
  2. Avoid harsh physical exfoliators which may damage your skin barrier.

Remember, overdoing any part of this regimen can lead to irritation and increased sebum production; hence moderation is key.

Always apply sunscreen after using exfoliants as they make your skin more susceptible to sun damage.

It’s also worth mentioning that professional treatments like facials or extraction procedures may help in removing these filaments. However, these should only be done by trained professionals under sterile conditions.

How To Treat Blackheads?

Blackheads are a type of acne that form when a clogged hair follicle in your skin is exposed to air. The exposure causes the oil and dead skin cells clogging the pore to oxidize and turn black.

To get rid of blackheads, you need to understand that they’re not dirt that can be scrubbed away.

Over-cleansing or harsh exfoliation can actually exacerbate the problem by causing skin irritation and increasing oil production. Instead, focus on gentle yet effective treatments.

Start by using products containing salicylic acid, an ingredient highly effective at unclogging pores.

It breaks down excess oils and dead skin cells which helps prevent blackheads from forming in the first place.

Regular use of a product with this ingredient can help treat existing blackheads and prevent new ones from appearing.

Another option is retinoids – vitamin A derivatives known for their potent ability to increase cell turnover rate.

This helps clear out blocked pores more rapidly, treating existing blackheads while preventing future formations.

Professional extraction could also be an option if you have severe or stubborn cases.

However, this should only be done by trained professionals as improper technique may cause scarring or infection.

Can We Extract Sebaceous Filaments Like Blackheads?

While you might be tempted to squeeze those tiny dots on your nose that resemble blackheads, it’s vital to know they’re likely not blackheads at all and treating them as such could cause more harm than good.

These are probably sebaceous filaments, which serve a big role in helping your skin stay moisturized by channeling oil from the sebaceous glands onto the surface of your skin.

When considering whether you can extract sebaceous filaments like blackheads, it’s key to understand more about their function and structure. 

Feature Blackhead Sebaceous Filament
Appearance Dark/black due to oxidation Light-colored or yellowish
Texture Firm; sticks out from skin Soft; flush with skin
Purpose Blockage of pore opening by dead skin cells and oils Natural part of pore lining; helps transport sebum

Unlike blackheads, whiteheads, pimples or breakouts, extracting sebaceous filaments isn’t recommended as they are a normal part of your skin functions.

Regular extraction can lead to damaged pores, increased oil production, and even infections.

If you’re troubled by their appearance though, there are ways you can reduce their visibility without causing damage.

Use gentle exfoliation methods and include ingredients such as salicylic acid or niacinamide in your skincare routine.

Salicylic acid aids in dissolving excess sebum while niacinamide helps control oil production.

Are Pore Strips Effective For Treating Blackheads And Sebaceous Filaments?

Are Pore Strips Effective For Treating Blackheads And Sebaceous Filaments?

 Pore strips can be effective for treating blackheads and sebaceous filaments, though not everyone experiences success with the product, to get rid of sebaceous filaments and blackheads.

Pore strips are applied directly to clean, dry skin and left in place for 10-15 minutes until they harden. They work by adhering to both blackheads and sebaceous filaments, thus pulling them away from the surface of the skin when removed.

While pore strips are great at getting rid of buildup on the surface of the skin, they do not address underlying causes linked to clogged pores such as poor hygiene or overproduction of oil.

They may also irritate sensitive skins types due to their adhesive properties. Therefore, if you’re considering using pore strips, it’s a good idea to consult with a skincare specialist first so that you use them properly and safely.

The most important part is for people using these products to establish a regular routine involving proper cleansing before applying pore strips to achieve optimal results.

Regular exfoliation is also recommended in combination with pore strip usage in order for any impurities within the follicles which have been cleared away by strip removal stays clear.



Blackheads and sebaceous filaments might look similar, but they are two very different skin issues that have to be treated independently.

Blackheads occur when your pores become clogged with dead skin cells and sebum. They’re usually small dark spots located on the face, neck, back, or chest.

Sebaceous filaments, on the other hand, are tiny hair-like structures made of sebum used to transport oil from glands to the surface of your skin.

They’re generally found all over your face – especially around the nose and cheeks – and don’t form clogs like blackheads do.

It’s essential to know how to tell them apart since squeezing either one can cause damage such as scarring or infection.

Stick to a gentle skincare routine – including chemical exfoliants and non-comedogenic products – if you want safer ways of reducing their visibility.
