Can Hyaluronic Acid Actually Shrink Your Pores?

Can Hyaluronic Acid Actually Shrink Your Pores?

What is Hyaluronic Acid?

Hyaluronic acid is a clear, gooey substance that is naturally produced by the body. It is found in large amounts in the skin, joints, and eye sockets.

Hyaluronic acid is a powerful humectant, meaning it attracts and retains moisture. This helps keep the skin hydrated, plump, and supple. It also provides cushioning for the joints and acts as a lubricant and shock absorber.

In the skin, hyaluronic acid binds to water to create a viscous, gel-like substance. This helps maintain skin hydration, protects against moisture loss, and delivers important nutrients.

Hyaluronic acid also regulates epidermal proliferation and differentiation. This means it signals skin cells to produce new, healthy cells while promoting the shedding of old cells. This keeps skin looking smooth and fresh.

With aging, the body's natural production of hyaluronic acid decreases. But applying it topically can replenish levels within the skin, helping restore a more youthful, hydrated complexion.

The Structure and Function of Pores

Pores are small openings in the skin connected to hair follicles and oil glands underneath. They serve important roles in the skin's function. Pores allow sweat and oils to reach the skin's surface and maintain a healthy balance. They also allow hair to grow out of the follicles.

Pores are formed as part of the natural process of skin growth and renewal. New skin cells are produced at the bottom layer of the epidermis and gradually rise to the surface. By the time they reach the outermost layer of skin, the stratum corneum, they are fully keratinized and flat in structure. The cells eventually shed off the surface through desquamation.

As this process occurs, the hair follicles and oil glands beneath form ducts that connect them to the skin's surface. The openings of these ducts onto the skin's surface are the pores. The size of pores is determined by the structure of the ducts and activity of the oil glands.

Pore size is largely genetic but can be affected by hormone levels, age, sun exposure, skin type, exfoliation, and skin care. Excess oil and dead skin buildup can cause pores to appear larger. Proper cleansing, toning, moisturizing and exfoliating helps minimize this. Diet, hydration levels, smoking and environmental exposures also impact pore appearance. While pores can dilate and constrict, the number of pore openings remains relatively constant throughout life.

Does Hyaluronic Acid Affect Pore Size?

There are several reasons why hyaluronic acid could theoretically affect pore size:

  • Hyaluronic acid is a powerful humectant, meaning it draws moisture from the environment into the skin. This hydration leads to plumper, firmer skin that retains elasticity. With well-hydrated skin, pores may appear smaller.

  • Hyaluronic acid stimulates collagen production in the skin. Collagen helps strengthen the skin's structure. With time, increased collagen could allow pores to retain their shape better and seem less enlarged.

  • Antioxidants are often paired with hyaluronic acid, and these can benefit skin on a cellular level. Less environmental damage could mean healthier tissue overall, including the lining of pores.

However, there is limited scientific evidence investigating hyaluronic acid's specific effects on pores:

  • One small study found that a cream with hyaluronic acid did not alter pore size over 8 weeks, though it did significantly improve skin hydration and elasticity. Participants noticed their pores looked less visible, likely due to surface-level plumping effects.

  • No rigorous, large scale trials have been conducted examining how hyaluronic acid supplements or topicals directly affect pore size with extended use.

Many people do share anecdotes about pores appearing smaller when using hyaluronic acid:

  • Reviews often mention pores seeming less noticeable, but it is unclear whether this is due to true shrinkage versus surface hydration effects. Photographic evidence is rarely provided.

  • Individual experiences likely vary depending on hyaluronic acid formulation, dosage, length of treatment, consistency of use, and personal skin characteristics. Some notice changes in weeks, while others require several months.

In summary, while hyaluronic acid likely improves various signs of skin aging, there needs to be more controlled research specifically examining potential pore size reduction over time. Individual results may certainly vary.

Risks and Side Effects

Hyaluronic acid is generally well-tolerated and considered safe for topical use. However, some people may experience mild side effects.

The most common side effect is skin irritation, redness, or rash where it is applied. This tends to be temporary and resolve once use is discontinued. Those with sensitive skin are more prone to irritation.

Less common side effects can include facial swelling, bruising, headaches, and flu-like symptoms. Severe allergic reactions are very rare but possible.

Hyaluronic acid should not be used by anyone allergic to any of the ingredients. It's not recommended for use during pregnancy or breastfeeding due to lack of safety data.

People who have certain chronic health conditions, upcoming surgeries, or take immunosuppressant medications should consult their doctor before using hyaluronic acid.

When used as directed at appropriate concentrations hyaluronic acid is well tolerated by most people. Start by patch testing a small amount and discontinue use if any concerning reactions develop. See a doctor for severe side effects.

How to Use Hyaluronic Acid for Best Results

Hyaluronic acid comes in different topical formats such as serums, creams, gels, and injectables. Here are some tips on using hyaluronic acid properly:


  • Apply 2-5 drops of hyaluronic acid serum after cleansing but before moisturizing.
  • Focus application on areas with enlarged pores like the nose, chin, and cheeks.
  • Allow serum to absorb fully before applying additional skincare products.


  • Use pea-sized amount and massage gently onto clean skin.
  • Focus on areas of concern and avoid eye area.
  • Allow cream to absorb before applying makeup.


  • Performed by licensed dermatologists or plastic surgeons.
  • Requires a series of injections spaced apart by several weeks.
  • Results can last 6-12 months depending on the individual.

When using hyaluronic acid topically, be sure to use it consistently for best results. Using it 1-2 times daily is ideal. It is safe to use with other pore-minimizing ingredients like retinol or AHAs as directed by your dermatologist.

Lifestyle Tips for Improving Pore Appearance

Consistently caring for your skin can help minimize the appearance of enlarged pores over time. Here are some helpful tips:

Exfoliate 2-3 Times Per Week
Gently exfoliating removes dead skin cells, dirt, and excess oil that can clog pores and make them appear larger. Use a chemical exfoliant containing alpha hydroxy acids (AHAs) or beta hydroxy acids (BHAs) or a gentle scrub with soft, round beads. Over-exfoliating can damage skin, so limit to 2-3 times per week.

Use Clay Masks Weekly
Clay masks are great for detoxifying clogged pores. The clay draws out impurities without stripping the skin. Apply a thin layer to clean skin, avoiding eye area. Leave on for 5-10 minutes then rinse. Use a clay mask about once a week.

Double Cleanse at Night
Oil cleansing is an effective way to thoroughly clean pores. Gently massage face with an oil-based cleanser to dissolve makeup, sunscreen, and other impurities. Rinse then follow with a water-based cleanser. This double cleanse helps keep pores clear.

Hydrate Skin Daily
Using oil-free, non-comedogenic moisturizer can improve skin hydration and elasticity. Well-hydrated skin appears plumper and healthier. Look for moisturizers with pore-minimizing ingredients like niacinamide and hyaluronic acid. Avoid heavy creams that could further clog pores.

Other Pore-Minimizing Ingredients

In addition to hyaluronic acid, there are other effective skincare ingredients that can help minimize and tighten the appearance of pores:


Also known as vitamin B3, niacinamide has anti-inflammatory and antioxidant properties to help reduce pore size and improve skin texture. It also regulates oil production and soothes skin, making pores look less noticeable.


Retinoids, such as retinol or tretinoin, chemically exfoliate the skin and help reduce the appearance of enlarged pores. Retinoids increase cell turnover, boost collagen production, and unclog pores from dead skin cells and debris. Use retinoids consistently to reduce the look of pores and diminish acne breakouts.

Salicylic Acid

Salicylic acid is a beta hydroxy acid that penetrates deep into pores to clear out dead skin cells, excess oil, and dirt buildup that cause visible pores. By reducing clogged pores, it can also prevent acne and improve overall skin texture and clarity.

Tea Tree Oil

Known for its anti-acne benefits, tea tree oil also has astringent properties that help tighten pores and reduce their appearance. Tea tree oil helps control excess sebum production that causes oily skin and enlarged-looking pores. Natural tea tree oil can sometimes cause sensitivity, so dilute it first or try products with tea tree oil already formulated in.

Using pore-minimizing ingredients like these can be very effective when combined with proper cleansing and moisturizing as part of a complete skincare regimen. Be patient and consistent when trying to improve pore appearance, as it takes time to see results. If you don't see changes after a few months, speak to your dermatologist about additional treatment options.

When to See a Dermatologist

Excessive pore size, oil production, clogged pores, and acne can significantly impact self-image and mental health. If over-the-counter skin care products are ineffective at managing these concerns, speaking to a dermatologist may help provide relief.

A dermatologist has advanced training in treating various skin conditions. During an initial consultation, they will evaluate your skin care regimen, diet, lifestyle factors, and medical history to uncover potential causes of enlarged pores and increased sebum production. From there, they may recommend prescription-strength skin care products, oral medications, or professional procedures tailored to your concerns.

For some, procedures like laser treatments, chemical peels, microneedling, and hydrafacial may visibly minimize pores with a series of appointments. In severe cases of enlarged pores and acne, a dermatologist might suggest solutions like cortisone injections, Xeomin/Dysport injections to limit oil gland production, or even surgically excising enlarged pores. Discussing all treatment options with an experienced dermatologist can help patients struggling with pore size distress make informed choices about professional skin care.

The Bottom Line

Studies show hyaluronic acid provides hydration by retaining moisture in the skin, which improves skin elasticity and plumpness. However, there is insufficient evidence showing topically-applied hyaluronic acid specifically shrinks pores or reduces their appearance.

Pores become more noticeable with excess sebum, dead skin buildup, loss of collagen, and skin inflamation. While hyaluronic acid is beneficial for skin health and hydration, it likely does not directly minimize pore size or appearance. Pore size is largely genetic and why pores appear bigger relates to skin aging and damage processes.

Overall, hyaluronic acid serum helps nourish and smooth skin, but other ingredients like retinoids, BHAs, and vitamin C target the underlying causes of large looking pores. Maintaining skin hydration with hyaluronic acid supplements a good skincare routine, but does not replace other evidence-based treatments for reducing pore appearance. Regular exfoliation, sun protection, and preserving collagen remain essential for skin texture and tone.

Main takeaways:

  • While beneficial for hydration, hyaluronic acid does not directly shrink pores. It may temporarily plump skin and reduce pore visibility.

  • Pore size relates more to genetics and natural aging; damage from UV, inflammation, and loss of elasticity make them appear larger.

  • For minimizing pores, focus on skincare ingredients targeting these root causes like retinoids and AHAs. Hyaluronic acid maintains moisture for smoother, healthier skin
