You can't change how big your pores are for good, but you can make them look smaller. Pore size is largely set by genetics, age, and oil production. What you can change is what fills the pore: excess oil, dead skin, and dryness that make it look wider and shinier. A steady routine that targets those beats any single product.
Why your pores look bigger
Each pore is the opening of a hair follicle, and the follicle connects to an oil gland. A 2006 study of 60 volunteers in the British Journal of Dermatology found that larger pores were linked to higher sebum output, along with age and being male. It was a small study, but it matches what most people notice: the areas that make the most oil look the most porous.
Oil and dead skin mix at the opening and make it look darker and wider. That's why shine that returns a couple of hours after cleansing is a useful clue. The oil is doing most of the visible work, so the fix is mostly about oil and surface buildup.
Can you make pores look smaller at home?
Yes, in the sense that matters when you look in the mirror. Ice does work for a few minutes, because cold briefly tightens the skin. The effect fades as the skin warms up, so think of it as a quick fix for one morning, not a routine.
Which ingredients help with the oil side?
Niacinamide is the best-studied option here. In a 2006 study, 2% niacinamide lowered sebum excretion in Japanese participants compared with placebo. A split-face trial on 30 Caucasian participants also pointed to lower oil. Both trials were small, so take the results as encouraging rather than settled.
Niacinamide won't change the size of the opening itself. It can calm the oil side, which is the part that makes pores look large and shiny. If you're new to it, our niacinamide guide explains what it does and what to expect.
A routine for pores that look bigger
If you want natural, at-home steps, keep it simple and steady. Most of the change comes from doing the same few things for several weeks.
- Cleanse every night, especially after sunscreen or makeup, so oil and dead skin don't sit in the openings.
- Start niacinamide two or three times a week. The studies used 2%, so there's no reason to start stronger. Build up only if your skin handles it well.
- Use a light moisturiser. Dry skin can look rougher around the pores, which makes them easier to spot.
- Wear sunscreen every morning. Sun exposure can soften skin over time, and firmer skin makes pores look less open.
Check what you layer niacinamide with, because a few combinations can irritate sensitive skin. Our pairings guide covers which ingredients to skip.

Why are the pores on my nose more visible?
The nose has many oil glands and follicles packed close together, so pores there stand out more than on the cheeks. Over time, age and sun can soften the skin around them, which can make pores look more open. Neither is a reason to panic, and both respond to the routine above.
What won't work
Be wary of anything that promises pores will close for good. No cream changes the underlying size of a pore. Pore strips pull out surface debris and can make skin look smoother for a day, but they can also irritate skin and do nothing for the oil underneath.
Pores won't disappear, but they can look much less obvious once oil and buildup are under control. Start with the basics and give it a few weeks.
FAQ
What ingredients shrink pores?
No ingredient changes the size of a pore for good. Niacinamide has the most direct evidence for calming oil output, so it's the most sensible place to start.
Can ice shrink pores?
Cold tightens the skin for a few minutes, so pores can look smaller briefly. The effect fades as the skin warms up.
Why are my pores on my nose visible?
The nose has many oil glands and follicles close together. Oil and dead skin fill the openings, which makes them easier to see.
Should I see a dermatologist about large pores?
Yes, if pores are painful or inflamed, or they don't look any better after a few months of a steady routine. A dermatologist can examine your skin in person and suggest what fits.
