If you have ever looked closely at your nose or chin and thought, âWhy do I have all these tiny black dots?â you are not alone.
This is one of the most common concerns I hear from clients, especially those with oily skin type, larger pores, or acne-prone skin. And almost every time, there is confusion between sebaceous filaments and blackheads.
They can look similar on the surface of your skin, but they are completely different things. Understanding that difference is what actually changes your results.
Letâs take a closer look at what is really happening inside of your pores, and what your skin actually needs.
What Are Sebaceous Filaments?
Sebaceous filaments are a completely normal part of your skin.
I cannot tell you how many times a client has come in convinced their pores are clogged, when what they are actually seeing is something their skin is supposed to have.
Sebaceous filaments are tube-like structures that line the walls of your pores and help move oil from your sebaceous glands to the surface of your skin. That oilâyour skinâs natural oilâplays an important role in protecting your skin and maintaining skin moisture.
They consist of sebum, dead skin cells, and natural debris that collect inside of your pores. Because they sit right at the skinâs surface, they often appear as tiny dots, sometimes gray, tan, or slightly darker.
Even medical sources like the Cleveland Clinic describe sebaceous filaments as a normal part of how your skin functions.
The important thing to understand is this: they are not a skin issue.
What Are Blackheads?
Blackheads are different. These are a type of acne, and they form when a pore becomes clogged.
What I see most often in acne-prone skin is a buildup of excess oil, dead cells, and debris forming a plug inside of the pore. That plug sits at the surface of your skin and darkens over time, creating a more defined dark dot.
This is what we call a blackhead.
In dermatology, blackheads are classified as open comedones and treated as part of acne. Ingredients like retinoids, benzoyl peroxide, and salicylic acid are commonly used because they address what is happening inside of the pore, not just what you see on the surface.
If you want to go deeper into the clinical side, organizations like the American Academy of Dermatology outline these as standard treatments. But in real life, what matters most is using the right products consistently and not overdoing it.
Why People Confuse the Two
This is where most people get tripped up.
Both sebaceous filaments and blackheads show up:
- Inside of your pores
- On the surface of your skin
- As tiny dots
But here is what I see in clinic:
Sebaceous filaments are usually:
- Evenly distributed
- Lighter in color (gray, tan, or slightly dark)
- Flat and smooth
Blackheads tend to be:
- More random
- Darker and more defined
- Slightly raised or textured
Once you know what youâre looking at, it becomes much easier to treat the right problem.
Why Sebaceous Filaments Look More Noticeable
Sebaceous filaments tend to stand out more when oil production is higher.
This is why I see them most in:
- Oily skin types
- Clients with larger pores
- Periods of hormonal changes
- Hot, humid weather (summer skin)
They can also look more noticeable when the skin is dehydrated. When the skinâs surface is not balanced, texture becomes more visible, even if oil production is high underneath.
The nose is the most common area because it has a high concentration of sebaceous glands and active oil flow.
Should You Squeeze Them?
This is where I see the most damage.
Clients come in after spending a lot of time trying to extract what they think are clogged pores, when they are actually just removing sebaceous filaments that will refill.
Squeezing can:
- Stretch the walls of your pores
- Damage the lining of your pore
- Trigger inflammation
- Lead to dark spots
Sebaceous filaments will always come back because they are a normal function of the skin.
Blackheads, on the other hand, can be treated and prevented, but not by aggressive picking.
Are Pore Strips or Clay Masks Helpful?
Pore strips are not something I recommend.
I see people damage their skin with these all the time. Instead of actually removing blackheads, they often lift and irritate the skinâs surface, leaving it more sensitive and prone to inflammation.
You might see something come off on the strip and feel like it worked, but most of what you are removing is surface debrisânot what is actually causing clogged pores. They do not change oil production, they do not prevent blackheads, and over time they can make pores look more noticeable by disrupting the skin and stretching the pore opening.
Clay masks are a different category.
They can help absorb excess oil and temporarily improve the appearance of the skin. Used occasionally, they can be helpful for oily skin. But when overused, I often see them dry out the skin, disrupt the skin barrier, and make texture and pores look worse.
Neither of these should be the foundation of your routine. If you want real results, the focus has to be on what is happening inside of your pores, not pulling at or over-drying the surface of your skin.
The Best Way to Treat Both
This is where your results actually come from, a solid skincare routine.
Gentle Cleanser
Start with a cleanser that removes buildup without stripping the skin.
The Skin+ Pro B5 Wash is designed to cleanse while maintaining hydration and supporting the skin barrier.
Salicylic Acid (Beta Hydroxy Acid)
Salicylic acid is one of the most effective ingredients for clogged pores and blackheads because it works inside of your pores.
There is strong research supporting its use in acne, including a review published in Molecules that highlights salicylic acid for treating excess oil and congestion. You can read it here.
The Skin+ BHA 2% Exfoliant is designed specifically for acne-prone skin dealing with buildup inside of the pores.
From experience, this works best when used consistently, not aggressively.
Gentle Exfoliation with Mandelic or Glycolic Acid
Exfoliation helps remove dead skin cells from the surface of your skin.
Glycolic acid has been used for years in clinical settings to improve acne and skin texture. Research in the Journal of Clinical and Aesthetic Dermatology supports its role in skin renewal, which you can review here.
That said, not everyone needs strong exfoliation. For many acne-prone clients, I start with gentler options like mandelic acid.
The Skin+ CytoClear is a great option for balancing oil production and supporting gentle exfoliation.
Retinol
Retinol supports healthy cell turnover and helps prevent buildup inside of your pores.
The Skin+ Daily A is used to support long-term skin clarity and prevent clogged pores from forming.
Benzoyl Peroxide
Benzoyl peroxide is most useful when blackheads are part of a larger acne pattern.
The Skin+ Acne Gel is used to calm inflammation and prevent new acne when used correctly as part of a routine.
Hydration with Hyaluronic Acid
One of the biggest mistakes I see is people skipping moisturizer because they have oily skin.
Hydration is essential for balancing oil production.
The Skin+ HylaVera provides lightweight hydration without clogging pores and supports skin moisture.
Pore-Clogging Watchlist (For Acne-Prone Skin)
If you are constantly dealing with blackheads, clogged pores, or visible sebaceous filaments, this is one of the first things I look at with clients.
A lot of skincare products can quietly contribute to congestionâeven when they feel good on the skin.
Instead of guessing, you can check your products using the Skin+ Ingredients Checker.
What to Watch For
Be cautious with products that:
- Feel heavy, thick, or waxy
- Leave a film on the skinâs surface
- Are overly rich or oil-based
- Sit on top of the skin instead of absorbing
These can trap dead skin cells, excess sebum, and debris inside of your pores.
Why This Matters
Sebaceous filaments are a normal part of the skin. But when pore-clogging products are layered on top, they can turn into:
- Blackheads
- A form of congestion
- Persistent tiny dots that do not improve
This is often when people start over-exfoliating or over-treating their skin, when the real issue is what they are using every day.
When Do You Need Professional Extraction?
Professional extraction can be helpful for true blackheads and stubborn clogged pores.
A trained acne specialist or board-certified dermatologist can identify what you are dealing with and safely remove congestion.
Sebaceous filaments typically do not require extraction because they will refill.
The Bottom Line
Sebaceous filaments and blackheads may look similar, but they are completely different.
Sebaceous filaments are a normal part of the skin that help move oil to the skinâs surface.
Blackheads are a form of acne caused by clogged pores and buildup.
The goal is not to eliminate pores or stop oil completely. The goal is to support healthy skin function with the right skincare routine and consistent care.
