Sebaceous filaments are most commonly found in the centrofacial areas and the alae nasae in postpuberal individuals with large facial pores and seborrhea.
A sebaceous filament is a tiny collection of sebum and dead skin cells around a hair follicle, which usually takes the form of a small, yellow to off-white hair-like strand when expressed from the skin. These filaments are naturally occurring, and are especially prominent on the nose.
Sebaceous filaments are structures that allow sebum to flow to the surface of the skin. When the body overproduces sebum, the sebaceous filaments can fill up. They may become visible and resemble very enlarged pores. People often confuse sebaceous filaments with blackheads.
Sebum is an oily semifluid substance produced by your skin's sebaceous gland. It lubricates and softens our skin and hair. Each of your hair follicles is associated with at least one sebaceous gland.
The technical term for an acne seed is a microcomedone. A microcomedone is a cluster of mostly dead skin cells that might be mixed with oil and comedogenic ingredients from pore-clogging products. It's called a micro-comedone because when it first forms, it is microscopic so it's invisible to the naked eye.
Sebaceous filaments are natural, healthy features that help move sebum to the skin's surface for moisturizing. Blackheads form when too much sebum, dead skin cells, and bacteria clog a pore. Because sebaceous filaments are a normal part of your skin's moisturizing process, they should be left alone.
Because pore strips aren't strong enough to remove blackheads, but are able to pull out sebaceous filaments, they end up stripping our skin of our natural oils and getting rid of the pore's protection from bacteria.
You can help get rid of the appearance of sebaceous filaments by cleansing and toning your skin each day and exfoliating weekly. The best way to treat sebaceous filaments is to focus on skincare that helps control oily skin. If your sebaceous filaments turn into blackheads, use a pore strip to unclog your pores.
Accutane is a vitamin A–containing a drug that helps regulate sebum secretion through sebaceous glands and aids in cell regeneration and the reduction of debris in pores. Antibiotics are only used in extremely rare cases where sebaceous filament infections become chronic and dangerous.
Picking & squeezing- it's bad to squeeze pores because any kind of picking, squeezing, or pulling stretches the elastin around the pores which can enlarge them. With constant squeezing, the pore can remain more stretched and enlarged over time without the ability to bounce back.
'You should absolutely not squeeze blackheads. Squeezing a spot can push the inflammation deeper and this can cause scarring of the skin,' she says. Squeezing a spot can push the inflammation deeper and this can cause scarring of the skin.
Try a Gentle At-Home Facial
“Beta hydroxy acids, like salicylic acid, are lipophilic, allowing them to mingle with oil deep within the pore and break up oil plugs.” This combination is a sebaceous filament-killer. To use this facial, apply a thin, even layer once or twice a week.
Why Is My Nose Oily? Your nose is likely oily because your sebaceous glands are producing more oil than necessary to keep your skin hydrated. The sebaceous glands beneath the pores in your skin are responsible for producing the natural oils, also known as sebum, that keep your skin healthy.
The Takeaway
While blackheads are a form of congestion typically seen on the nose and forehead, sebaceous filaments are actually part of your skin—they're tube-like structures that help facilitate oil secretion from the sebaceous glands to your skin.
Your pores can become clogged for a number of reasons – excess oil resulting from hormonal changes, dry skin, a buildup of dead skin cells, or dirt and oil becoming stuck beneath the surface.
Utilize Active Ingredients Like BHA, AHAs, and Retinoids
Allawh. “They not only help treat sebaceous filaments, but also prevent [new] sebaceous filaments from forming.”
"Any active ingredients that work to exfoliate the skin will improve the look of sebaceous filaments," says Dr. Linkner. "Common examples of active ingredients include retinol, salicylic acid, and glycolic acid."
Pore strips are unlikely to cause any real damage. However, they may cause redness and skin irritation, especially for those with skin disorders like rosacea or psoriasis, or for patients using prescription acne medications.
As mentioned, sebaceous filaments are healthy, the goal is not to try and remove them completely (which you would do well to achieve anyway). The objective is to prevent them from turning into breakouts or cysts. We would recommend a gentle exfoliator to break down and dissolve the sebum plugs.
Salicylic acid is studied to reduce the size of sebaceous filaments. Known for its minimizing effect on pores, benzoyl peroxide helps reduce inflammation while getting rid of bacteria and excess oil.
It's irreversible damage,” says Dr. Henry. Damaging your skin by squeezing or picking can also cause inflammation, hyperpigmentation and scarring. Squeezing additionally introduces bacteria, oil and dirt from your hands into your pores, which can lead to more blackheads.
Nose pores are inherently larger. If the pores on your nose get clogged, this can become more noticeable. Clogged pores typically consist of a combination of sebum and dead skin cells that get stock in the hair follicles beneath. This creates “plugs” that can then harden and enlarge the follicle walls.
Oil dissolves oil, so an oil cleanser can actually eliminate excess sebum, as well as daily dirt and grime (aka, the exact recipe for sebaceous filaments). "I especially like oil cleansers for oily, congested skin," says Britta Plug, holistic esthetician and mbg Collective member.
It's actually completely normal for you to have some holes initially after removing blackheads. This is because the dirt and debris filling the pore is suddenly gone, leaving a small space.
