Treatment guides from a clinic in Myeongdong, Seoul

Large Pores

Pores cannot be closed, and any plan that starts from that promise will disappoint. What can change is how visible they are, and that depends on which of several quite different causes is making yours stand out.

What makes pores look large

Four causes, and they rarely appear alone.

Oil production. Larger, more active sebaceous glands need larger openings. This is mostly constitutional, which is why it tends to run in families and to be worse across the nose, inner cheeks and forehead.

Blockage. A pore filled with oil and skin cells is wider than an empty one, and the visible plug adds contrast. Clearing it makes an immediate difference to how the skin reads, and it refills.

Lost collagen and elasticity. A pore is held open or closed by the tissue around it. As that support weakens with age and sun exposure, pores stretch and tip into the teardrop shape seen on the mid cheeks. This is the cause that responds least to anything applied on the surface.

Old acne scarring. Some of what people call enlarged pores is fine pitted scarring, particularly if there is a history of acne in that area. It has sharper edges than a pore and it does not fill with a plug.

Sun damage sits behind two of these, thinning and disorganising the support structure over years. Smoking does the same thing faster.

How to tell which cause you have

Look in strong side light rather than overhead light, and look at the shape. Round pores dotted evenly across an oily area point to gland size and blockage. Elongated pores drifting downwards, mostly on the cheeks, point to lost firmness. Sharp-edged pits that are still visible when you stretch the skin are more likely to be scarring.

Two more useful observations: how long after cleansing your skin takes to look shiny again, and whether the pores look better or worse when you lie down. Skin that improves noticeably lying flat is telling you that gravity and laxity are part of the picture.

A consultation examines pore shape and distribution under magnification, how oily the skin actually is, skin thickness and firmness, and whether there is scarring mixed in. It should also ask what you have been using, because over-exfoliated skin looks more porous than it is.

What addresses each cause

What is causing it What the treatment category is
Heavy oil production Treatment a doctor may prescribe, and sometimes skin botox for oiliness and pore appearance
Blocked pores and blackheads Extraction and gentle exfoliation in a clinic skin care programme
Lost collagen around the pore Microneedling radiofrequency such as Potenza, or fractional laser resurfacing
Thin, poor-quality skin overall Collagen stimulation with Rejuran, Juvelook or other skin boosters
Laxity in the lower face pulling the skin Radiofrequency or ultrasound lifting, as a separate goal that helps the impression
Fine pitted scarring Resurfacing and needling approaches, planned as scar treatment
Surface dullness exaggerating the shadows A clinic programme alongside the device work

What does not help

Pore strips and suction tools. They clear the plug, irritate the opening and change nothing about its size.

Scrubs and stacked acids. Over-exfoliated skin is rougher, redder and more porous-looking, and the response is usually to exfoliate more.

Filler. There is no volume problem here, and injecting one does not follow.

Toning lasers. They work on colour. Pores are texture.

Hydrating facials as the treatment. They make skin look better for a few days, which is worth having and is not a change in pore appearance.

Lifting treatments sold as pore treatments. Tightening the lower face can improve the overall impression, but if your pores are oily and blocked across the nose, a lifting device is the wrong category.

Realistic timeline and how many sessions

Extraction shows immediately and lasts weeks. Oil control shows over a few weeks and wears off over months. Collagen-based improvement — the part that changes pore shape — needs a course of three to five sessions, three to four weeks apart, and it is judged two to three months after the last one.

Downtime depends on the device: needling and fractional work leave redness and roughness for a few days. Plan the stronger sessions for the end of a trip rather than the start.

What to ask at the consultation

  1. Which of my pores are oil and blockage, and which are loss of firmness?
  2. Is any of this scarring rather than pores?
  3. What is the realistic ceiling in my case, described plainly?
  4. What maintenance keeps the result, and how often?
  5. What should I stop using, as well as start?

FAQ

Can pores be permanently closed?

No. Pores are openings that have to exist. Treatment makes them less noticeable by reducing oil, clearing blockage and firming the skin around them, and the improvement needs maintaining.

Why do mine look worse on the cheeks than the nose?

Pores on the nose tend to be large because the glands there are large. Elongated, teardrop-shaped pores across the cheeks more often reflect skin that has lost firmness, which is a different treatment question.

Do pore strips and suction devices help?

They remove the surface plug and leave the opening behind, often more irritated than before. Repeated use on the same area is not a route to smaller pores.

How long does the improvement last?

Months rather than permanently. Oil production and skin firmness both return to their baseline, so most people keep a session or two a year in the plan.
