Large pores: what shrinks them and what does not

Dr Ong Jin Khang · MMC 45245 · LCP holder · The Retreat Clinic, Setia Alam

Nothing closes a pore, but large pores can look smaller: published work names oil, loss of firmness and larger follicles as the causes, and supports retinoids, peels, some lasers and skin injections with partial, gradual results. In two split-face laser trials pore counts fell on both sides, and in one hyaluronic acid study the mean improvement was 40 per cent.

A pore has no muscle to close. The studies measure how large it looks, and the improvement is partial and gradual.

Quick answer

Nothing closes a pore, but large pores can look smaller: published work names oil, loss of firmness and larger follicles as the causes, and supports retinoids, peels, some lasers and skin injections with partial, gradual results.

  • Why: a review names high sebum excretion, reduced elasticity around the pore and increased follicle volume as the three main causes.
  • What has support: sun protection, prescription retinoids, peels, some lasers and some hyaluronic acid injections, each with partial results.
  • What has no support here: pore strips and cold water, which no source read tests.
  • Expect: gradual improvement, repeated treatment and no promise of smooth, poreless skin.

Why do my pores look so large?

A review of the literature gives three major clinical causes: high sebum excretion, decreased elasticity around the pore, and increased hair follicle volume. Chronic recurrent acne, sex hormones and the skin care routine also affect pore size. The same review calls enlarged pores a cosmetic concern rather than a medical one, and says treatment has to be individualised because the causes differ from person to person.

This is also why one product rarely fixes every face. Oil widens the opening through the day, loss of firmness lets the opening gape, and sun damage coarsens the surface so the shadow around it deepens. The article on why you cannot shrink a pore explains each of the three, and the texture, pores and scarring page shows how the clinic sorts them.

Do heat and humidity in Malaysia make pores bigger?

No source read measures pore size in Malaysia or the effect of heat and humidity on it, so no figure can be given. What is established is that oil is one of the three main causes, and that sun exposure and ageing are the usual reasons for the surface coarsening and loss of firmness that follow. Skin that feels oily by afternoon is at least a reason to look at the cleansing routine and the sunscreen, which are covered below.

What do studies support for open pores?

A 2016 review in Cutis says enlarged pores are mainly treated by addressing sebum production and skin ageing, and it covers topical retinoids, chemical peels, oral antiandrogens, and lasers and devices. Only its abstract was read for this article, so it is used for the list of options and not for figures.

In practice the options sort into the following groups. The trial figures for lasers and injections are in the next two sections.

  • Daily sun protection. It slows the ageing and surface coarsening that widen the look of pores. See the article on sunscreen in a tropical climate.
  • Topical retinoids. They are listed in the review. In Malaysia tretinoin and adapalene are not self-service products, as the article on retinoid law sets out, and a doctor decides whether one suits the skin.
  • Chemical peels. They are listed in the review. Depth decides what a peel can do and the risk of a dark mark afterwards on Asian skin, as the article on peels in Malaysia explains.
  • Oral antiandrogens. They are listed in the review and are prescription medicines for specific hormonal causes, decided by a doctor.
  • Surface clearing. A facial can lift the plugs that make pores look darker, and the article on what a HydraFacial does says plainly that congestion refills.

Can lasers shrink pores?

Two split-face trials report that visible pores fell, with differences in side effects that matter on Asian skin. Both compared a fractional 1064 nm picosecond laser with a 1565 nm nonablative fractional laser, one on each side of the face.

TrialPeople and sessionsPore resultSide effects reported
Qian 2023, Shanghai19 completed, 5 monthly sessionsPore counts fell significantly on both sides; no significant difference 3 months after the last sessionHyperpigmentation 5.3% (picosecond) vs 52.6% (1565 nm); pain score 1.48 vs 4.45
Liu 2024, Nanjing25, 3 sessions 2 weeks apartPore numbers fell significantly on both sides; no significant difference between lasersPigmentation did not differ significantly; pain lower with the picosecond laser

Both trials were small, and the first reported hyperpigmentation in more than half of the 1565 nm treated sides. The devices are named in the studies and cannot be assumed for any other laser. Dr Ong performs PicoSure at the clinic, and the texture page places it in selected texture work, but the picosecond laser in these trials is a fractional 1064 nm device, and the trials do not show that PicoSure shrinks pores. The article on pigment laser side effects covers the dark-mark risk in more detail.

Do skin boosters or hyaluronic acid injections help pores?

Small studies of hyaluronic acid injected into the skin report smaller pores, but they test particular products and some have no control group. In a Beijing study of 42 people given low molecular weight hyaluronic acid two to five times, the mean improvement rate was 40.03 per cent and no nodules or pigmentation were reported, with no control group described. In a randomised, double-blind split-face study from Bangkok, 29 people completed three sessions, pore volume measured by 3D imaging fell on both sides through week 32, and the product containing glycerol gave a 24.2 per cent greater reduction (p = 0.038), with mild pain, swelling and bruising.

The clinic offers skinboosters, and Dr Ong injects them. The skinboosters page and the article on skinboosters and fillers describe them as improving hydration and skin quality, and neither presents them as a pore treatment. The studies above do not prove that any skinbooster used at the clinic changes pore size.

Does a pore strip, cold water or a scrub close pores?

No trial of pore strips or cold water is among the sources read, and a pore has no muscle to open or close. Cold water changes how the skin feels for a short time. A strip lifts the surface plug and leaves the follicle as it was. Aggressive scrubbing and stripping can inflame the follicle opening and prompt more oil, which is the pattern the earlier pore article describes.

What should a daily routine for large pores look like?

A quiet routine is the one the evidence points to: gentle cleansing, a sunscreen every morning, and one active at a time when a doctor has advised it. The review that names sebum, elasticity and follicle volume as the three causes also lists skin care routine as a factor in pore size, so what is applied matters. Harsh scrubs and several acids layered together can inflame the follicle opening and prompt more oil. A retinoid or peel is started slowly and adjusted to how the skin tolerates it, and in Malaysia the prescription ones come through a doctor.

What results can I expect?

Expect a visible but partial change over weeks to months, kept up with a routine and repeat treatment. The trials above followed people for months at most, which is not the same as years, and none of them reported poreless skin. Genetics and skin type set the starting point, and the review calls for treatment matched to the cause. Any claim to close pores for good goes beyond what these studies show.

When are large pores a sign of something else?

Large pores can sit alongside acne, rosacea and hormonal change, so the cause is worth checking when they come with other signs. The reviews link enlarged pores to chronic recurrent acne, to rosacea among other conditions, and to sex hormones. See a doctor if there are painful or deep spots, flushing and visible vessels, a sudden change in oiliness, or a single spot that grows, bleeds or changes colour. A pore that looks large on a lone patch is also worth showing to a doctor rather than treating at home.

What does the clinic offer, and what does it not?

Dr Ong performs PicoSure at the clinic and injects skinboosters, and HydraFacial Syndeo sessions are done by certified therapists with LED in every session (see the HydraFacial page). The clinic does not offer RF microneedling including Potenza, plain microneedling or fractional CO2, which are the devices many pore searches suggest. The article on why it does not offer RF microneedling gives the reasoning, and nothing in these studies depends on those devices.

Common questions

Can large pores be made smaller permanently?

Not by closing them: a pore is a hair follicle opening and has no muscle. Studies measure how large pores look, and the improvement is partial. In one hyaluronic acid study the mean improvement rate was 40.03 per cent, and the trials follow people for months, not years.

Which treatment works for open pores in Malaysia?

No single treatment is ranked first in the studies read, and the cause decides the choice. Reviews name excess oil, reduced elasticity and larger follicles as the causes, so the plan may involve a prescription retinoid, a peel, a laser or skin injections, chosen after the skin is examined.

Do pore strips or cold water close pores?

No trial of pore strips or cold water is among the sources read. A pore has no muscle, so it cannot be closed or opened, and cold water only changes how the skin feels for a short while. A strip lifts the surface plug and does not change the follicle.

Do lasers shrink pores?

Two split-face trials of a fractional 1064 nm picosecond laser and a 1565 nm fractional laser both reported fewer visible pores. One trial found hyperpigmentation in 52.6 per cent on the 1565 nm side against 5.3 per cent on the picosecond side. Results from one device do not carry over to another.

Do skin boosters help large pores?

Some injected hyaluronic acid products have been studied for pores. A split-face study of 29 people found pore volume fell through week 32, and an uncontrolled study of 42 people reported a 40.03 per cent mean improvement. These are small studies of specific products, not of skin boosters as a class.

When should I see a doctor about my pores?

See a doctor if the pores come with painful, red or deep acne, if the skin changes suddenly, or if a single spot grows, bleeds or changes colour. Reviews link enlarged pores to acne, rosacea and sex hormones, so a cause may need treating before the pores themselves.
