I was watching a very confronting (but satisfying) video of a pore strip being ripped off a stranger’s nose the other day on Instagram when I noticed the comments section: everyone was losing their minds about sebaceous filaments and the fact that they were supposedly being unceremoniously ripped out of this person’s face.

I considered sebaceous filaments and realized I wasn’t entirely sure what they are. Are they good? Are they bad? Are they normal? Should we be using aggressive pore strips to extract them?

After some digging (and inspecting my own skin), I asked my aesthetician and we arrived at the conclusion that the nasal “blackheads” I’d been picking at for years on end were actually sebaceous filaments – a normal but also interesting part of the skin’s structure that can take on a quasi-blackhead appearance, tricking us all into believing our pores are filled with dirt and dead skin when in fact, they’re not. Who knew?

To get to the bottom of this complexion epiphany, I enlisted the expertise of the pore master himself, Dr. Dennis Gross. Here, Dr. Gross breaks down what sebaceous filaments are, how they’re different from blackheads, and ways in which you can reduce their appearance. Because you can!

What are sebaceous filaments

Dr. Dennis Gross: Sebaceous filaments line the inside of your pores and help move sebum or oil from your sebaceous glands to the surface of your skin. They are a key part of how your skin naturally self-hydrates.

Does everyone have them? 

Dr. Dennis Gross: Yes – every person has them. They are natural; however if your skin is over-producing oil, they can cause pores to look enlarged and more visible, almost as if the pore is stretched. You cannot fully get rid of them, but you can help reduce their appearance with daily, gentle chemical exfoliation, using a cleanser formulated with alpha and beta hydroxy acids and an oil-free moisturizer.

How do they differ from a blackhead? And how can someone tell the difference in their own skin? 

Dr. Dennis Gross: Sebaceous filaments are necessary to transport sebum from your sebaceous gland to skin’s surface. Blackheads are a form of acne – they form when sebum, dead skin cells clog the pore and it oxidizes, creating a black bump. Blackheads will appear as raised, black bumps while enlarged sebaceous filaments appear like flat, grey-ish blackheads. At times, sebaceous filaments can be a pre-cursor to black heads.

How are they treated – can you suggest some ingredients to help?  

Dr. Dennis Gross: You can treat blackheads and reduce the appearance of sebaceous filaments with the same ingredients:

  • Alpha and beta hydroxy acids – particularly glycolic and salicylic acid – can help decongest pores. 
  • Retinol – increases cell turnover and keeps the pores’ linings clear. 
  • Farnesol – kills acne-causing bacteria. 
  • Phytic Acid Pentasodium – dissolves waxy plugs deep within pore walls.
  • Use oil-free moisturizers.
