Can You Shrink Pores? What Hyaluronic Acid Can Do

Large pores are one of those skin concerns that seem to get more noticeable the more you look at them. Maybe your foundation settles into them by midday, or the skin on your nose and cheeks looks textured under bright bathroom lights. It's no surprise that "how to get rid of large pores" is one of the most common skincare questions out there, or that hyaluronic acid shows up in so many of the answers.

Before you build a routine around it, it helps to know what's realistic. Pores are a normal, necessary part of your skin, and their size is mostly set by genetics, so no ingredient can make them disappear or permanently shrink them, hyaluronic acid included. What HA can do is keep your skin hydrated, smooth and calm, which helps pores look less noticeable and makes the ingredients that clear pores easier on your skin.

This guide covers what actually causes large pores, what hyaluronic acid can and can't do for them, how to use HA in a pore-friendly routine and which popular pore tricks to skip.

TL;DR

• You can't shrink pores for good: Pore size is mostly genetic. You can make pores look smaller and less noticeable, but not change their actual size.

• Hyaluronic acid helps pores look less obvious: It hydrates without adding oil, smooths rough texture and offsets the dryness from pore-clearing ingredients like acids and retinol.

• HA works best as part of a team: Pair it with gentle cleansing, acid exfoliation, retinol and daily sunscreen, the steps that keep pores clear and skin firm.

• Skip the quick fixes: Cold water, steaming, pore strips and squeezing don't change pore size, and some of them make pores look worse.

Why You Can't Get Rid of Your Pores

Pores are the small openings where hair follicles meet the surface of your skin. The oil glands connected to them release sebum, the natural oil that helps keep your skin protected and supple. In other words, pores aren't a flaw to fix. They're part of how healthy skin works.

Their size isn't something you can change much, either. As dermatologist Jane Wu, MD, told Cleveland Clinic, "Genetics mostly determines your pore size," and "you can't permanently shrink them." That's why people in the same family often have similar-looking pores, and why two people using the same products can get very different results.

Pores also don't have muscles, so they can't open or close. Hot water doesn't open them, and cold water doesn't close them. Ice or a chilled roller can make skin look tighter for a few minutes, but the effect fades quickly. Our post on washing your face with cold water covers what temperature does and doesn't do for your skin.

What Makes Pores Look Bigger?

Even though you can't change your pore size, a lot of everyday factors change how visible your pores are. Here are the most common ones:

Can Hyaluronic Acid Shrink Pores?

No, hyaluronic acid can't shrink pores, and no topical ingredient can change their actual size. But HA can make a real difference in how noticeable your pores look, mainly by fixing one of the most overlooked causes: dehydration.

What Hyaluronic Acid Does for Your Skin

Hyaluronic acid is a humectant, meaning it draws water into the skin and helps hold it there. Your skin already makes its own HA, which is a big part of why topical HA is so well tolerated across skin types, including oily and acne-prone skin. Because it adds water rather than oil, it hydrates without the heavy feel that makes people with large pores nervous about moisturizing. Our guide to hyaluronic acid molecular weight explains why multi-weight formulas hydrate at more than one level.

Why Dehydrated Skin Makes Pores More Noticeable

Oily and dehydrated aren't opposites. Oil and water are two different things, so your skin can produce plenty of oil while still lacking water. Harsh cleansers, hot water, acids and retinol can all leave skin feeling tight, even when it looks shiny by afternoon.

When the surface of your skin is dry and rough, light hits it unevenly, and texture, including pores, stands out more. Dry skin is also easier to irritate, and the AAD notes that inflammation can make pores more noticeable. Well-hydrated skin looks smoother and plumper, so the same pores simply read as less obvious. Our guides to dry vs. dehydrated skin and hyaluronic acid for oily skin go deeper on how to tell the difference.

What HA Can and Can't Do for Pores

There's very little research on topical hyaluronic acid and pore appearance specifically, so think of HA as the step that supports everything else in your routine rather than a pore treatment on its own. If you're worried about breakouts, our post on whether hyaluronic acid can cause acne covers why it's considered a low-risk choice for acne-prone skin.

How to Use Hyaluronic Acid for Large Pores

1. Cleanse gently. Use a non-comedogenic cleanser and warm water, and pat your skin almost dry, leaving it slightly damp.

2. Apply your treatment step first, if you're using one. On exfoliation nights, apply your acid before HA. On retinol nights, apply a thin layer of retinol first.

3. Pat on hyaluronic acid. Press 1 to 2 drops of Pure Hyaluronic Acid Serum onto your face and neck, adding a little more if your skin still feels tight.

4. Seal it in with a light moisturizer. HA pulls water into the skin, and a non-comedogenic moisturizer helps keep it there. Oily skin types can use a gel or lotion texture.

5. Finish with SPF in the morning. Use a broad-spectrum sunscreen of SPF 30 or higher every day.

Pair HA With Steps That Keep Pores Clear

Hyaluronic acid keeps skin hydrated and smooth, but it works best alongside the steps that clear pores, manage oil and protect firmness.

Cleanse Gently, Twice a Day

According to the American Academy of Dermatology, "Cleansing twice daily can unclog pores, prevent clogged pores, and reduce oiliness." Use a gentle, non-comedogenic cleanser with warm water, not hot, since the AAD notes that hot water can irritate skin and make pores look larger.

Exfoliate With Acids, Not Scrubs

The AAD says that "exfoliating may make pores less noticeable," but it also warns against scrubbing, rubbing or picking, since irritation makes pores stand out more. Chemical exfoliants are usually a better fit:

• Salicylic acid (BHA) is oil-soluble, so it can work inside the pore. The AAD notes that "studies show salicylic acid can unclog pores." Our guide to salicylic acid serums explains how to start safely.

• Lactic acid (AHA) smooths surface buildup and rough texture. Cosmedica's 5% Lactic Acid Treatment + Hylasyn pairs lactic acid with hyaluronic acid to help offset dryness. Start two or three nights a week, and read our lactic acid guide to learn more.

Not sure which to pick? Our breakdown of AHA vs. BHA can help you match the acid to your skin type.

Add Retinol at Night

Retinol helps clear the dead skin that clogs pores, and, as Dr. Wu explains to Cleveland Clinic, "Retinol also increases the production of collagen, which keeps skin supple." Firmer skin around each pore helps it look smaller over time. Start with a thin layer two or three nights a week. Cosmedica's Retinol Serum 2.5% is designed for night use, and our barrier-first plan for starting retinol helps if your skin tends to react. The AAD advises against using retinol if you're pregnant or breastfeeding.

Balance Oil With Niacinamide

If oil is your biggest pore concern, niacinamide can help keep it in check. Cosmedica's 10% Niacinamide + Zinc Treatment Serum is an easy morning step, and our guide to niacinamide for pores explains what it can and can't do. Keep it in a separate routine from retinol and lactic acid, as Cosmedica recommends.

Wear Sunscreen and Choose Non-Comedogenic Products

Sun damage weakens the collagen that keeps skin around your pores firm, so the AAD recommends "a broad-spectrum, water resistant sunscreen with an SPF 30 or higher" every day. The AAD also advises using "only non-comedogenic skin care products and makeup," so check the labels on your moisturizer, sunscreen and foundation.

A Simple Routine for Large Pores

Here's how it fits together. Keep retinol and acids on separate nights so your skin isn't overwhelmed, and use hyaluronic acid in every routine.

Give it time. Smoother, better-hydrated skin can show up within days to weeks, while changes in firmness from retinol take longer. For more help, see our skincare routine for oily skin and guide to improving skin texture.

Pore Myths Worth Skipping

• "Cold water closes your pores." Pores don't have muscles, so they can't open or close. Cold water may make skin look tighter for a few minutes, but it doesn't change pore size.

• "Steam opens your pores." Steam can soften oil on the surface, but it doesn't open pores. Very hot water and steam can also irritate skin, which makes pores look larger.

• "Pore strips clean out your pores." Strips can pull out the top of a clog, but pores refill with oil quickly, and the tugging can irritate skin.

• "Squeezing gets rid of clogs." Dr. Wu warns that squeezing pores or using extractor tools "can cause scarring and harm the skin."

• "Oily skin doesn't need hydration." Skipping hydration can leave skin tight and irritated, which makes pores more noticeable, especially if you're using acids or retinol.

When to See a Dermatologist About Large Pores

If a consistent routine hasn't made enough of a difference after a few months, a board-certified dermatologist has stronger options. According to Cleveland Clinic, these include:

• Prescription medications: For acne-prone patients, medications like isotretinoin or spironolactone can reduce oil production, which decreases the appearance of pores.

• Professional microneedling: In-office devices use needles of 1.5 to 2 mm to stimulate collagen, compared with 0.5 mm or less for at-home tools. Our post on whether microneedling works covers what to expect.

• Laser treatments: Lasers resurface the skin and stimulate collagen, usually in a series of sessions spaced 4 to 8 weeks apart, with longer-lasting results than at-home options.

It's also worth seeing a dermatologist if large pores come with persistent breakouts, since treating the acne itself often makes the biggest difference.

Our Perspective: Pores Aren't a Flaw

We'll be honest: no product, including our hyaluronic acid serum, can erase your pores, and we'd rather tell you that up front than sell you a promise. Pores are part of healthy skin. What hyaluronic acid does well is keep your skin hydrated, smooth and comfortable, so it looks its best and handles the stronger steps in your routine without drying out. At a normal distance, most people notice your glow long before your pores.

FAQ

Can hyaluronic acid shrink pores?

No, hyaluronic acid can't shrink pores or change their actual size. It can help pores look less noticeable by hydrating your skin without adding oil, smoothing rough texture and offsetting the dryness that acids and retinol can cause.

Can you get rid of large pores permanently?

No, you can't get rid of large pores permanently. Pore size is mostly determined by genetics, and pores are a normal part of healthy skin. You can make them look smaller by keeping them clear, controlling oil, staying hydrated and protecting your skin's firmness with retinol and daily sunscreen.

Does hyaluronic acid clog pores?

Hyaluronic acid is not known to clog pores and is considered non-comedogenic. Your skin makes its own HA, and it hydrates with water rather than oil. Choose a simple, fragrance-free formula, and check the rest of the ingredient list if you're acne-prone.

Is hyaluronic acid good for oily skin with large pores?

Yes, hyaluronic acid is a good fit for oily skin with large pores. Oily skin can still be dehydrated, and HA adds water without adding oil. Keeping skin hydrated helps the surface look smoother, which makes pores less noticeable.

Can I use hyaluronic acid with salicylic acid or retinol?

Yes. Apply your salicylic acid or retinol first, then follow with hyaluronic acid and a moisturizer. HA helps offset the dryness and tightness those ingredients can cause, which makes them easier to use consistently.

What causes large pores on your face?

Large pores are mainly caused by genetics, excess oil, clogged pores, and loss of firmness from aging and sun damage. Hormonal shifts can increase oil production, and dehydrated or irritated skin can make pores more noticeable.

When should I see a dermatologist about large pores?

See a board-certified dermatologist if a consistent routine hasn't helped after a few months or if large pores come with ongoing acne. A dermatologist can offer prescription treatments, professional microneedling or laser treatments that go beyond what at-home products can do.
