Sebaceous Filaments: Vs Blackheads & How to get rid
Sebaceous filaments are a common skin occurrence, but are often mistaken for other skin concerns, specifically blackheads. But the core difference between sebaceous filaments and blackheads, is that sebaceous filaments aren’t actually a sign of blocked pores, nor are they a skinc condition. In fact, they’re a natural part of our skin. In this article, we’ll discuss in more detail what exactly sebaceous filaments are, why they’re mistaken for blackheads and whether you can reduce their appearance.

What are sebaceous filaments?
Sebaceous filaments are naturally occurring structures within the pores of the skin. They are composed of sebum (oil), dead skin cells, and microbes that line the walls of hair follicles. These filaments manifest on the skin's surface as tiny dots, which are often mistaken for blackheads. But unlike blackheads, sebaceous filaments are not a sign of clogged pores but are part of the skin's normal function.
What causes sebaceous filaments?
Sebaceous filaments are caused by the natural functions of the skin, specifically how sebum moves to the surface of your skin. Sebum is an oily substance produced by sebaceous glands, playing a vital role in maintaining skin hydration and protecting against environmental aggressors. As sebum flows through the hair follicle to the surface of the skin, it mixes with dead skin cells and microbes. When the skin overproduces sebum, the sebaceous filaments can become more noticeable.
Where do sebaceous filaments commonly appear?
Sebaceous filaments tend to appear in areas with a high concentration of sebaceous glands, such as the nose, chin, and forehead.
Sebaceous filaments are normal!
Sebaceous filaments are a physiological feature of all skin. They can be more noticeable on oily skin, as overactive sebaceous glands lead to an excess of sebum that fills up and may stretch out sebaceous filaments.

What's the difference between Sebaceous filaments vs blackheads
Sebaceous filaments and blackheads, while often mistaken for each other, represent distinct skin phenomena. Filaments are naturally occurring structures within pores that move sebum to the surface of the skin. They appear as tiny dots, usually more flesh-toned. Blackheads, on the other hand, are an open comedone caused by clogged pores that appear black due to oxidation. These differences influence how each should be addressed.
Feature | Sebaceous Filaments | Blackheads |
---|---|---|
Nature | Natural part of skin | Type of blemish |
Appearance | Grayish/yellowish, flush with skin | Dark, often appear as a bump on your skin |
Cause | Normal sebum production | Clogged pores and oxidation |
Essentially, sebaceous filaments are a normal part of your skin, while blackheads are a skin concern that needs to be managed.
So can you get rid of sebaceous filaments?
You can't get rid of sebaceous filaments, but you can manage their appearance with proper skincare that manages excess oil production.
8 tips for minimising the appearance of sebaceous filaments
1. Use a gentle cleanser
Use a mild, pH-balanced cleanser to remove makeup, excess oil and dirt without stripping your skin's natural oils. Always use a gentle cleanser, and avoid over-washing, as this can increase trigger oil glands to produce more sebum and exacerbate the problem.
2. Exfoliate the skin regularly
Exfoliating 2-3 times per week with chemical exfoliants can keep pores clear of dead skin cells and reduce the prominence of sebaceous filaments. Alpha-hydroxy acids (AHAs) like glycolic acid and beta-hydroxy acids (BHAs) like salicylic acid can help to gently exfoliate the skin and prevent pores from becoming clogged.
3. Consider retinol
Retinol helps speed up skin cell turnover, which can help reduce excess sebum buildup, which in turn helps reduce visible sebaceous filaments. Start with a low concentration and use it consistently, as it can take several weeks to see results.
4. Incorporate a clay mask
Clay masks, particularly those containing kaolin or bentonite clay, can help to absorb excess oil and draw out impurities that block pores, which can minimise the appearance of sebaceous filaments while visibly reducing enlarged pores.
5. Keep the skin hydrated
Hydrated skin is less likely to overproduce sebum. Make sure to incorporate a moisturiser formulated for your skin type in your regular morning and evening skincare routine. Oil-free moisturisers containing gentle exfoliating ingredients can help with very oily skin prone to enlarged pores.
6. Use non-comedogenic products
Choose makeup and skincare products that are non-comedogenic (won't clog pores) and free of heavy oils.
7. Address diet and lifestyle factors
A balanced diet and healthy lifestyle can influence sebum production, which in turn affects the appearance of enlarged pores and visible sebaceous filaments. Foods rich in omega-3 fatty acids and antioxidants may promote healthier skin.
8. Avoid squeezing or aggressive scrubbing
Squeezing sebaceous filaments will do more harm than good. Never squeeze sebaceous filaments (or blackheads, for that matter), and avoid excessive scrubbing, as this can worsen oil production and increase irritation.
