Can you permanently shrink your pores?

No. Pore size is largely determined by genetics, so no product or procedure can permanently make a pore smaller. What you can change is how visible pores are. Keeping them clear of oil and dead skin, reducing excess sebum, and protecting the collagen around them with sunscreen and retinoids can make pores look noticeably smaller.

Does cold water or ice close pores?

Pores don't open and close, so cold water and ice can't close them. Cold can briefly tighten the skin and reduce puffiness, which may make pores look slightly smaller for a few minutes, but the effect fades quickly. Consistent use of exfoliants, retinoids, and sunscreen has a much more lasting effect on pore appearance.

What is the best ingredient for large pores?

There's no single best ingredient, but salicylic acid and retinoids have the strongest track record. Salicylic acid (0.5% to 2%) clears oil and debris inside the pore, while retinoids speed cell turnover and support collagen over time. Niacinamide at 2% to 5% is a gentle add-on that may help reduce oil and improve texture.

How long does it take to see smaller-looking pores?

Most people notice clearer, less prominent pores after about 4 to 6 weeks of consistent salicylic acid or niacinamide use. Retinoids typically take 8 to 12 weeks to improve texture, and their collagen-related benefits build over several months. Give any new routine at least six weeks before deciding whether it works for you.

Do pore strips make pores smaller?

Pore strips remove the top part of the plugs in pores on the nose, so pores can look clearer right after use. However, the plugs refill within days, the pore itself doesn't shrink, and frequent use can irritate skin. A leave-on salicylic acid product is a gentler, longer-lasting way to keep pores clear.

Why are my pores getting bigger with age?

As you age, collagen and elastin around each pore break down, and the skin loses some firmness. That slight sagging can make pores look wider or elongated, especially on the cheeks. Years of sun exposure speed up this process. Daily broad-spectrum sunscreen and a nightly retinoid are the most practical ways to slow it down.

How to Shrink Pores: What Works and What's a Myth

Here is the honest answer: you can't permanently shrink your pores, because their size is largely set by genetics. What you can do is make them look noticeably smaller. Pores look bigger when they're stretched by oil and dead skin, when the skin around them loses firmness, and when they're outlined by trapped debris. Treat those three causes and pores read as smaller, often within 4 to 12 weeks.

The approach that works for most people is unexciting but reliable: gentle cleansing, a leave-on exfoliant such as salicylic acid, a retinoid at night, niacinamide if you want extra oil control, and daily sunscreen to protect the collagen that holds pores tight. Quick fixes like ice, pore strips, and "pore-closing" toners only change how your skin looks for a few minutes.

Below, we break down why pores look large, which ingredients have real evidence behind them, what to skip, and when in-office treatments are worth it.

Why Pores Look Large in the First Place

A pore is the opening of a hair follicle, and each one connects to a sebaceous (oil) gland. You can't open or close pores like doors; they have no muscles. Their visible size depends on a few factors:

Genetics. This is the biggest one. If your parents have visible pores, you probably will too.
Oil production. Pores are most noticeable on the nose, forehead, and cheeks next to the nose, where oil glands are largest and most numerous. More sebum flowing through a pore can stretch it.
Clogging. When oil mixes with dead skin cells, it forms a plug. Plugs that oxidize at the surface turn dark (blackheads), which makes the pore's outline stand out.
Age and sun damage. Collagen and elastin act like scaffolding around each pore. As they break down with time and UV exposure, the skin sags slightly and pores can look elongated or wider.
Hormones. Androgens increase oil production, which is why pores often become more prominent during puberty and can fluctuate with the menstrual cycle.

The practical takeaway: you're not trying to shrink the pore itself. You're trying to keep it clear, reduce how much oil stretches it, and keep the surrounding skin firm.

Can You Actually Shrink Pores? Myths vs. Reality

A lot of advice about pores is built on the idea that they open and close. They don't. Here's how common claims hold up:

Claim	Reality
"Hot water opens pores, cold water closes them"	Temperature doesn't change pore size. Cold can briefly tighten skin, but the effect fades within minutes.
"Ice cubes or chilled rollers shrink pores"	Same as above: a temporary tightening, not a lasting change.
"Pore strips get rid of pores"	Strips pull out the top of a plug, but plugs refill in days, and frequent use can irritate skin.
"Astringent toners close pores"	Alcohol-heavy toners can make skin look tighter for a moment while drying and irritating it.
"Squeezing clears pores for good"	Squeezing can push debris deeper, cause inflammation, and leave marks or scars.
"Retinoids and exfoliating acids can make pores look smaller"	True. These are the most reliable over-the-counter options.
"Sunscreen helps with pores"	True, over the long term, because UV breaks down the collagen that supports pores.

Also worth knowing: magnifying mirrors make pores look far larger than anyone sees them in normal conversation. If you're evaluating your skin, a regular mirror at arm's length gives a more realistic picture.

Ingredients That Make Pores Look Smaller

Salicylic acid (BHA)

Salicylic acid is oil-soluble, so it can work inside the pore lining and loosen the mix of oil and dead cells that stretches pores and creates blackheads. Over-the-counter products typically contain 0.5% to 2%.

How to use it: A leave-on 1–2% BHA liquid or serum is usually more effective than a cleanser, which rinses off quickly. Start 2–3 nights a week and build toward daily if your skin tolerates it.
What to expect: Clearer-looking pores on the nose and cheeks in roughly 4–6 weeks.

Retinoids (retinol, adapalene)

Retinoids speed up skin cell turnover, which helps prevent plugs from forming, and over months they support collagen production, which helps skin around pores stay firm. Over the counter, you'll find retinol (often 0.25%–1%) and adapalene 0.1% gel, which is available without a prescription in the US and is approved for acne.

How to use it: Apply a pea-sized amount at night, 2–3 times a week at first, then increase as tolerated. Expect some dryness or flaking in the first few weeks.
What to expect: Changes in texture and pore appearance usually take 8–12 weeks, and collagen-related improvement takes longer.
Caution: Avoid retinoids if you're pregnant or trying to conceive, and always pair them with daily sunscreen.

A dermatologist can prescribe stronger retinoids, such as tretinoin, if over-the-counter options aren't enough. Our guide on how to use retinol covers how to start without irritation.

Niacinamide

Niacinamide (vitamin B3) is one of the gentlest pore-focused ingredients. Some studies suggest it can reduce sebum production and improve the look of pores, though the evidence is modest and based on fairly small trials. Its big advantage is tolerability: most people, including those with sensitive skin, can use it daily.

How to use it: Look for 2%–5% in a serum or moisturizer, once or twice a day. Higher concentrations (10% and up) aren't clearly better and are more likely to sting.
What to expect: Less shine and slightly smoother-looking skin over 4–8 weeks.

More detail is in our article on niacinamide benefits for skin.

Glycolic and lactic acid (AHAs)

Alpha hydroxy acids are water-soluble and work on the skin's surface, smoothing texture and brightening. They don't penetrate pores the way salicylic acid does, but by evening out the surface they can make pores look less defined. They're a good option if you also want to address dullness or uneven tone. Use them a few nights a week, and don't stack them with a retinoid on the same night when you're just starting out.

Clay masks

Kaolin and bentonite clay absorb surface oil and can make skin look matte and pores less obvious for a day or so. Think of them as a helpful extra once or twice a week, not a treatment that changes pores over time.

A Simple Routine to Minimize Pores

You don't need ten products. A focused routine works better and is easier to stick with.

Morning

Gentle, non-comedogenic cleanser (or just water if your skin is dry)
Niacinamide serum (optional)
Lightweight, oil-free moisturizer
Broad-spectrum sunscreen, SPF 30 or higher

Evening

Gentle cleanser; double cleanse if you wore heavy sunscreen or makeup
Active ingredient: alternate salicylic acid and a retinoid on different nights at first
Moisturizer

A few rules that make a real difference:

Introduce one new active at a time and give it 2–3 weeks before adding another.
Don't skip moisturizer. Over-drying can make skin look rough and doesn't reduce oil in a lasting way.
Choose products labeled non-comedogenic or oil-free, including makeup and sunscreen.
Be patient. Most pore-focused ingredients need at least a month before you can judge them.

If your skin is oily overall, our skincare routine for oily skin walks through product choices in more detail. That said, the right combination of actives depends on your skin type and other concerns, like acne, sensitivity, or dark spots.

Habits That Make Pores Look Bigger

Some everyday habits work against everything above:

Picking and squeezing. It stretches the pore, inflames the surrounding skin, and can leave dark marks or scars.
Harsh scrubs. Gritty physical exfoliants can cause micro-irritation and redness that makes texture look worse.
Skipping sunscreen. Cumulative UV damage weakens the collagen around pores, so pores often look larger with age on sun-exposed skin.
Over-cleansing. Washing more than twice a day, or using stripping cleansers, can irritate skin without meaningfully reducing oil.
Sleeping in makeup. Leftover makeup, sunscreen, and oil sit in pores overnight and contribute to clogging.
Using too many actives at once. Combining strong acids and retinoids before your skin is ready often leads to irritation, which makes skin look worse, not smoother.

In-Office Treatments for Enlarged Pores

If you've used a consistent routine for three months or more and still want more improvement, a board-certified dermatologist can offer options that go further than home care:

Chemical peels. Professional-strength glycolic, salicylic, or other peels exfoliate more deeply than at-home products. Usually done as a series.
Microneedling. Controlled micro-injuries stimulate collagen production, which can firm the skin around pores. Professional devices reach deeper than at-home rollers, so results are typically more noticeable.
Laser and energy-based treatments. Resurfacing and non-ablative lasers can improve texture and stimulate collagen. Several sessions are usually needed, and downtime varies by device.
Prescription medications. For pores linked to very oily or acne-prone skin, a dermatologist can prescribe topical retinoids such as tretinoin, or, in appropriate cases, oral medications that reduce oil production.

Results from procedures vary, and none of them permanently change your genetic pore size. A dermatologist can tell you which option fits your skin tone, budget, and tolerance for downtime.

When to See a Dermatologist

Visible pores are normal and harmless. Still, it's worth booking an appointment if:

Enlarged pores come with persistent acne, painful bumps, or scarring
A single pore looks unusually large, raised, or filled with a hard plug that doesn't clear (this can be a dilated pore or a cyst, which a dermatologist can evaluate and safely remove)
Your skin reacts badly to over-the-counter actives, with burning, ongoing redness, or peeling
You're considering procedures and want guidance on what's realistic for your skin

The Bottom Line

You can't permanently shrink pores, but you can make them look much smaller. Keep them clear with salicylic acid, support firm skin with a retinoid, use niacinamide for oil control if you like, and wear sunscreen every day. Skip ice, pore strips, and squeezing, which offer only brief or harmful results. Give any new routine at least 6 to 12 weeks, and talk to a dermatologist if home care isn't enough or your pores come with acne or scarring.
