What are sebaceous filaments?

Sebaceous filaments are natural thread-like structures of a pale white to yellow color that line the walls of the skin's pores. They represent a specific functional state of the sebaceous follicles: their purpose is to help channel the flow of sebum from the sebaceous gland to the skin's surface, where it protects the skin from dehydration and environmental aggressions. Sebaceous filaments are most often found in areas of the face that secrete the most sebum (lateral wings of the nose, nasolabial fold, cheeks, and forehead).

Not present in children, they appear during puberty and become more frequent in adulthood. Although everyone has them, people with a oily skin or large pores are more likely to notice them. Indeed, they become visible when the pore fills with sebum and dilates. Moreover, follicular filaments regenerate quickly, within a span of 3 to 5 weeks.

Sebaceous Filaments: What are the Differences Compared to Blackheads?

Sebaceous filaments are often mistaken for blackheads. Indeed, they present in the same way and are visible in the same areas. It happens that the tip of the seborrheic filaments darkens slightly, which is explained by the oxidation of the fatty acids that make up the sebum covering it when exposed to air, thus resembling blackheads.

Firstly, the sebaceous filament is a natural structure around hair follicles, while the blackhead is a skin disorder that results from the obstruction of pores by the formation of a cluster of oxidized sebum and dead cells. Furthermore, the open comedones are located on the skin's surface, whereas sebaceous filaments are embedded deeper into the skin without blocking anything.

Finally, you can also distinguish them by conducting a small test. When blackheads are extracted (which is generally to be avoided), they appear as a dark plug. Conversely, if you squeeze a sebaceous filament, it releases a column of waxy sebum, sometimes accompanied by a dark tip.

Should sebaceous filaments be removed?

While unsightly, sebaceous filaments are not considered imperfections per se, they are not bothersome, nor do they have any pathological value. Therefore, there is no reason to try to remove them manually, as this could inflame the skin by pressing on this area and promote the proliferation of bacteria within the weakened pore, leading to the eruption of a pimple.

Furthermore, even if you attempt to extract or squeeze them, this will lead to their rapid return within 30 days, or even much sooner if you have oily skin. However, it is possible todiminish their appearance by adopting a suitable skincare routine by controlling sebum production and minimizing pore congestion.

How to diminish the appearance of sebaceous filaments?

To make them less noticeable, it is necessary to adopt a suitable skin cleansing and care routine:

  1. Morning and evening, wash your face with a gentle cleanser to regulate sebum production and unclog pores from the mixture of dead cells, pollution particles, dust, makeup residues... For instance, you might want to use a purifying cleansing gel with zinc to rid the skin of excess sebum, especially if you have oily skin;

  2. Then apply a purifying toner with salicylic acid. Unlike AHA which are water-soluble, this liposoluble exfoliant has the ability to dissolve excess sebum that clogs the pores. This BHA works deep within the pores to unclog them ;

  3. Hydrate your skin daily with a moisturizer suitable for your skin type. Ideally, choose a zinc-based cream if you have oily skin to limit sebum production;

  4. In addition, it is recommended to gently exfoliate your skin weekly and apply a purifying mask made of green clay and black charcoal for its astringent effect. The green clay and charcoal will absorb excess sebum, effectively unclog pores, and tighten them.
