Blackheads or sebaceous filaments? What the dots on your nose mean

Lean toward the bathroom mirror and your nose looks sprinkled with pepper. You squeeze, something pale and waxy comes out, and a few weeks later the dots are back. Nobody told you that might be your skin doing its job.

The short answer: Some of those dots are blackheads, a mild form of acne where a plug blocks the pore. Many are sebaceous filaments, a normal part of the pore that carries oil to the surface. They look alike but behave differently. Colour, size, surface and how fast they return will usually tell you which you have, and that decides what’s worth doing about them.

What are sebaceous filaments?

A pore isn’t an empty hole. It’s the opening of a hair follicle, and the lining of that follicle holds a thin column of oil and dead cells that helps oil travel up to the surface. That column is the sebaceous filament.

A 1976 German-language study in Archives of Dermatological Research described them as whitish-yellow cylinders that can be squeezed out of oily areas of the face. They were most common in the centre of the face and on the sides of the nose, in adults past puberty with large pores and oily skin. Each one had a wall of 10 to 30 layers of dead cells around a mixture of oil, bacteria, cell fragments and a single hair. After a filament was squeezed out, the follicle refilled within 30 days. The authors called filaments a common variant of ordinary sebaceous follicles.

That study is about fifty years old, so hold the details loosely. The main idea has lasted. Cleveland Clinic says everyone has sebaceous filaments, that they help sebum reach the skin’s surface, and that they aren’t acne. A 2021 case report in Dermatology Practical & Conceptual describes them the same way: yellowish to off-white collections of oil and dead cells around hair follicles.

What is a blackhead?

A blackhead is an open comedone: a pore that has filled with oil and dead skin cells but stays open at the surface. The American Academy of Dermatology (AAD) says the dark dots aren’t dirt, and that scrubbing at them only worsens acne. If the pore closes over instead, you get a tiny white or flesh-coloured bump, a whitehead.

The colour comes from the plug meeting air. Sources describe the chemistry a little differently. Some point to the oil oxidising, others to the pigment inside the dead cells. They agree on the part that matters: air, not grime.

Cleveland Clinic draws the practical line. In a blackhead, a plug of sebum sits at the surface and stops oil moving through the pore. In a filament there’s no plug, so oil still flows freely.

How do you tell them apart?

Nothing here replaces a dermatologist’s eye, but there are patterns to look for.

Dermatologist Sandra Lee, writing for her own skincare brand, says filaments usually stay tiny and flat while blackheads can grow, averaging 1 to 2 mm if left alone. A dermatologist quoted by Daily Vanity says filaments tend to be about the same size across the nose, while blackheads vary.

Real noses are messier than a table. Both are made of oil and dead cells, so the line blurs, and you can have both at once. Dr Lee points out that because the contents are the same, the treatments overlap.

Why is it always the nose?

Because that’s where the oil glands are busiest. Cleveland Clinic lists a few things that make filaments easier to see:

• Age. Oil glands grow and make more oil around puberty. In your 40s and 50s skin starts to loosen and pores can widen, which shows filaments up more.
• Thick hair follicles. Thicker follicles make filaments more visible.
• Dry skin. Too much sun or too much washing can dry skin out. The glands may then work harder, and the pores may look larger.

It’s the same T-zone pattern we saw in our piece on oily skin that still feels dry: the nose and forehead carry the most oil, so they’re where the dots show.

Can you get rid of them?

Blackheads, yes. Filaments, no. Cleveland Clinic is direct about it: you can’t get rid of sebaceous filaments, though you can make them look smaller. They’re part of how the pore works.

Squeezing doesn’t change that. If you do get something out, the pore fills up again within 30 days, and Cleveland Clinic notes your nails are much stronger than your skin, so pressure can cause real damage.

Pore strips are the other tempting option. Cleveland Clinic says they’re meant for blackheads but can lift filaments too, and that doing so can dry the skin. An older study summarised by Healthline found strips do remove blackheads, but the effect was temporary. Dermatologists interviewed by Essence put it more bluntly: strips pull out filaments and surface gunk, the result doesn’t last, and better options exist.

What actually helps blackheads and whiteheads?

The AAD’s advice for blackheads and whiteheads is a retinoid to unclog pores, and adapalene is the one you can buy without a prescription. It also suggests a benzoyl peroxide wash. Give it six to eight weeks. If you still see blackheads after that, a dermatologist can do a comedo extraction or prescribe a stronger treatment.

Salicylic acid has a long track record here too. A 2015 review in Clinical, Cosmetic and Investigational Dermatology calls it a comedolytic, meaning it helps loosen pore plugs, and says it works by loosening the junctions between skin cells rather than dissolving them. The AAD also lists salicylic acid washes alongside benzoyl peroxide for acne.

Retinoids can cause peeling and changes in skin colour. Cleveland Clinic says using them every other day, or alongside a moisturiser, reduces those effects.

And for filaments?

The goal is a calmer-looking pore, not an empty one. Cleveland Clinic suggests a routine with salicylic acid or a retinoid, a mild daily cleanser, a regular moisturiser, non-comedogenic products and keeping your hands off your face.

It also suggests gentle exfoliation with a facial scrub, while the AAD advises against scrubbing blackheads. A sensible reading is that if you use a scrub at all, keep it brief and light, and stop if your skin stings.

There’s also some evidence for niacinamide and oil output. In a 2006 study led by Zoe Draelos, 100 Japanese volunteers used a 2% niacinamide moisturiser or a placebo for four weeks. The niacinamide group had significantly lower sebum excretion after two and four weeks. A second study, a six-week split-face trial in 30 Caucasian volunteers, gave somewhat different results: the authors concluded niacinamide may lower casual sebum levels, the oil sitting on the skin’s surface, in that group. It’s small, and oil output isn’t the same as how the pore looks. Nothing in this research suggests a product changes the pore itself.

What does this look like in a real day?

Picture Sana. She’s invented, a composite, not a customer. She lives somewhere hot and humid and counts about thirty dots across her nose. Every Sunday she uses a pore strip, then a gritty scrub. By Wednesday the dots are back and her nose is pink and tight. She decides they’re stubborn blackheads and buys a stronger scrub.

Then she looks properly, in daylight, with the skin pulled flat. Most of the dots are pale grey and flat, spread evenly across her nose. Three or four near the crease are dark and slightly raised. The first group is filaments, which strips and scrubs can’t remove for good. The second group is the real blackheads.

She drops the strips and the scrub. She washes gently morning and evening, moisturises, and adds an over-the-counter adapalene gel for the few dark ones, eased in the way the label says. She gives it six to eight weeks.

At the end she isn’t asking whether the dots are gone, because most of them never will be. She’s asking whether the dark raised ones have cleared and whether her nose has stopped feeling tight. That’s a question the strip could never answer.

What’s a simple routine?

Four small rules.

Wash morning and evening with a mild cleanser. The AAD recommends twice-daily washing for acne-prone skin, and Cleveland Clinic suggests a mild cleanser with warm water for filaments. Harshness seems to matter more than frequency, as the oily skin piece covered.

Moisturise afterwards. Choose a non-comedogenic product, since that’s what Cleveland Clinic advises for filaments.

Treat only what you have. If you have true blackheads, that’s adapalene, for six to eight weeks. If it’s mostly filaments, an occasional salicylic acid product or niacinamide may make them less obvious, and the rest is acceptance.

Leave them alone. No squeezing, no strips, no nails.

When should you see a dermatologist?

See one if blackheads haven’t improved after six to eight weeks of treatment, which is the AAD’s window. See one sooner if you have deep, painful, red lumps, which the AAD says can leave permanent scars without professional help. Cleveland Clinic also suggests seeing a provider if over-the-counter products can’t keep your filaments in check, because they can prescribe medication that lowers oil production.

And a dark spot that’s new, growing, changing colour or bleeding isn’t a blackhead. Have it checked.

Where does Mugtea fit?

Mugtea is meant for the wash step. It starts as a paste, turns to cream with a little water, then opens into a foam. Its cleansing base is SCI-led, a coconut-derived isethionate, with microfine kaolin to pick up excess oil, glycerin and panthenol for how skin feels afterwards, and salicylic acid, an exfoliating ingredient. It’s formulated for normal, oily and combination skin, aims to be mild, and is meant to clean oily skin without leaving it feeling pulled.

Used consistently, Mugtea can somewhat reduce blackheads and whiteheads. The salicylic acid is a comedolytic, an ingredient that helps loosen what plugs a pore, and the kaolin picks up excess oil. A wash only touches your skin briefly, so expect gradual change. Give it the six to eight weeks the AAD suggests for blackheads before you judge it.

Now the limits. Mugtea is a cleanser, so the change is partial, and it won’t remove sebaceous filaments, because nothing does. Stubborn or deep blackheads may still need a leave-on treatment like adapalene, or a dermatologist’s extraction. Salicylic acid can bother some skin, so patch test on your jawline first, use the daily wash only for a week, and stop if your skin objects. If your skin is reactive, or you’re on a prescription treatment or using a retinoid, ask your dermatologist first. On an evening when you have time, you can leave it on for 2 minutes as a pack, then rinse.

Dark dots on your nose aren’t a verdict on how clean you are.
