TL;DR: Key Takeaways
- Sebaceous filaments = normal sebum channels; refill in hours; can't be 'removed'
- Open comedones (blackheads) = keratin plugs that oxidise dark; extractable
- Pore size is largely genetic — but visibility is manageable
- Salicylic acid, niacinamide, retinoids > pore strips
- AI texture tools count both — sudden change matters more than absolute count
The Three Things You're Seeing
- Normal pore: small, even opening, skin-coloured or grey, no plug
- Sebaceous filament: tiny grey-yellow dot, uniform across nose, refills fast
- Open comedone: dark, slightly raised, extractable plug, may be inflamed
Why the Distinction Matters
Sebaceous filaments are a normal feature of oily skin — they can't be permanently removed because they refill. Chasing them with harsh extractions, scrubs, or pore strips damages the pore edge and makes the pore look bigger over time.
Open comedones, on the other hand, are a mild form of acne and respond to real treatment. Ignoring them can let them become inflamed spots and eventually leave scars.
Get a pore + texture score from a selfie
Our AI selfie analysis maps pore visibility by region and tracks change across scans.
What Actually Reduces Each
- Filaments: gentle 1–2% salicylic acid a few times weekly + niacinamide 4–10%
- Filaments: avoid picking, scrubs, and daily pore strips
- Comedones: adapalene 0.1% gel nightly + benzoyl peroxide 2.5% every other morning
- Cystic or scarring acne: see a dermatologist — oral treatment may be needed
- All: daily SPF 30+ (UV weakens collagen, making pores look larger)
Tracking Change
Take a close nose-and-cheeks selfie every 4 weeks in identical light. Compare pore count and darkness. See the skin texture analysis explained guide for how AI aggregates all of this into a single score, and the acne spot treatment guide if any comedones become inflamed.
Why one check is rarely enough
A single scan tells you about one spot, on one day. But skin changes are about patterns over time — a new mole appearing, a slow shift in shape, size or colour, or a patch that simply isn't healing. Monitoring the same spots side-by-side, week after week, surfaces the subtle changes a one-off check will always miss — and gives you a clear record to show a clinician if something needs a closer look.

Frequently Asked Questions
No. Many of the dark dots on the nose are actually sebaceous filaments — normal, tiny channels of sebum that everyone has. True blackheads are open comedones plugged with oxidised keratin, and they can be extracted. Sebaceous filaments refill within hours and cannot be permanently removed.
A normal pore is a small even opening, often skin-coloured or grey. An open comedone is darker, sits proud of the skin, has a clear plug in the centre, and often shows a slight raised rim. Under 5× magnification, the difference becomes obvious.
Pores are not muscles — they can't contract. But you can reduce their apparent size by clearing the sebum inside, minimising oil overproduction (BHA, niacinamide, retinoids), and protecting collagen (SPF, retinoids) so the pore edges stay firm.
They remove the surface plug of some blackheads and most sebaceous filaments — for a day. They don't shrink pores and can irritate the skin edge. A better long-term routine: salicylic acid 1–2% cleanser or serum a few times per week.
Not for normal pore appearance. See a clinician if you have dozens of inflamed spots that leave scars, cystic acne, or worsening pore size in the past year — a topical retinoid or an in-office treatment can prevent permanent scarring.
