Large pores before and after: what the photo shows and what it hides

Pores are the easiest before-and-after to fake in all of facial aesthetics. No treatment required: swap hard frontal light for diffuse light from above, zoom out, ask the person to relax their face, and the pores disappear. They disappear from the photo. They stay on the face.

This is not a skeptic's theory. It is the reason you look at a result online, decide you want it, have the procedure, and feel yours fell short — when often yours came out the same, and the one in the photo was just lighting.

So let's start with the tedious, useful part: what has to be identical in both photos for a before-and-after to mean anything, and only then talk about what treats pores.

How to read a pore before-and-after

Four variables change how pores look without changing the pores:

• Light direction. Side light or hard frontal light casts a shadow inside each opening, and that shadow is what you read as a "large pore". Diffuse light erases the shadow. If the "before" has side light and the "after" has ring light, the comparison is dead right there.
• Distance and lens. A close-up exaggerates the center of the face. One step back changes how the same skin reads.
• Oiliness at the moment. Oily skin reflects light and outlines every opening. The same skin, blotted ten minutes earlier, shows less.
• Immediately after a procedure. There is a fine, subtle swelling that follows almost any skin procedure and tightens the area for a few days. A photo taken in that window shows smooth skin that is not yet a result.

An honest before-and-after is taken in the same light, at the same distance, with the same expression, at the same time of day, and without makeup in either. When you cannot confirm that, treat the photo as advertising, not evidence — ours included.

And there is something almost nobody says: pores improve a little in photos and a lot in person. Skin texture is a three-dimensional experience. It changes under your fingers, in how makeup sits, in the elevator light. Flattening that into a JPEG is exactly the format that loses the most information.

What causes large pores

The pore you see is the opening of the pilosebaceous follicle — the channel through which hair and the sebum produced by the sebaceous gland come out. Three forces widen that opening:

The second row is the one that changes the conversation. While the pore is round and concentrated in the T-zone, the story is sebum. When it starts to read as an elongated teardrop, pulled downward, spread across the cheek, what changed was not oil production: it was the surrounding tissue, which lost firmness and stopped holding the edge of the opening. That is why so many people in their early forties swear their skin "got oilier" when it actually got less firm.

Add to that: accumulated sun damage, which breaks down collagen and elastin exactly in the layer that supports the pore; and comedones, which are pores clogged and stretched by what is inside them — something different from a pore enlarged by structure, and something that responds to cleansing and actives, not to technology.

Can you actually close your pores?

No. And any text that promises it is selling words.

Pores have no muscle; they do not open or close. What exists is apparent diameter, and it shrinks when you address the causes: less sebum inside the channel, more collagen around the edge, a more even surface reflecting light more uniformly.

This distinction is not pedantry. It defines what you will count as success. Someone who walks in expecting porcelain skin walks out frustrated with a real 30% improvement in appearance. Someone who walks in understanding that the goal is to reduce the shadow inside the pore and even out texture recognizes the result when it arrives.

The flip side is good news: this is one of the areas where maintenance works very well. Pores are not an event; they are a routine. And here, routine delivers.

What helps shrink large pores

Topical actives, where most of the result lives

Pores are one of the few topics in facial aesthetics where the cream genuinely carries weight. Not because it "penetrates the skin and rebuilds" — but because the most common cause is sebum and keratin in the channel, and that is surface.

• Retinoids — normalize cell turnover inside the follicle and, with continued use, act on the firmness of the surrounding skin. They are the active with the best track record for this purpose. They require gradual introduction and daily sunscreen.
• Salicylic acid — oil-soluble, it gets into the oily channel and unclogs it from the inside. It is the "acid for pores" people are searching for.
• Niacinamide — the honest answer to "which vitamin closes pores". It is vitamin B3, and it helps with oil control and the skin barrier. It closes nothing. It improves appearance.
• Alpha hydroxy acids (glycolic, mandelic) — work on the surface and even out texture.
• Sunscreen, every day — the only item on the list that protects the collagen supporting the edge of the pore. Skipping it means treating and undoing at the same time.

Before buying anything, check the product's registration with Anvisa, the Brazilian health regulator. That applies to skincare as much as to procedures.

Surface procedures

Chemical peels and laser — RUV offers both — act on skin renewal and texture. They even out the surface, help with the oiliness and clogging component, and improve the way light reflects off the face. This is the approach that gives the most visible result in the least time, and the one that depends most on a series protocol, not a single session.

Collagen stimulation, for the teardrop pore

When the cause is loss of support, the target is not the channel — it is the tissue around it.

At RUV we use Ultherapy, by Merz, and what defines its action is the transducer: the more superficial ones stimulate collagen, the deeper ones act on fat. For skin texture and firmness, the work is on the superficial front. The same device that shows up in a contouring plan shows up here — what changes is the depth at which the energy is delivered.

Skin boosters come in from the other side: they hydrate the skin from within and improve tissue quality, which changes radiance and the way the surface returns light. They are not volume and do not change shape. They change skin.

And this is where timing matters. New collagen takes weeks to organize, and an honest reading of the result happens after that. A before-and-after taken the week after a collagen-stimulation session is photographing something else.

Does ice close pores?

It does not. Ice causes vasoconstriction and temporarily reduces the fine swelling of the skin, which makes the surface momentarily smoother. It lasts minutes.

Same logic for the hot water that "opens pores" before cleansing: the steam softens sebum and keratin, which makes extraction easier. The pore did not open. Its contents softened.

Neither is harmful in normal amounts, and the immediate effect is real enough to be useful before an event. Just do not confuse it with treatment.

What about the Korean pore routine?

What the Korean routine does well, and what explains a good part of its results, is consistency and light layers: double cleansing at night, gentle chemical exfoliation at a controlled frequency, fluid-textured hydration, and sunscreen religiously every day. There is no secret ingredient. There is adherence.

What it does badly when imported without judgment: ten steps on skin that cannot tolerate them, over-exfoliation, and the idea that more product means more result. Irritated skin produces more sebum and makes pores more visible. I have seen nine-step routines worsen what a three-step routine would have fixed.

Pores in mature skin are a different problem

In skin over forty, visible pores are almost never about oiliness. They are about support, and they often come with sun damage and thinning skin.

The common mistake is attacking with the oily-skin arsenal — astringents, aggressive exfoliation, drying cleansers. That assaults a barrier that is already more fragile and does not touch the cause. What works in this scenario is the collagen approach, a well-introduced retinoid and sunscreen, with months of patience.

Safety

Surface procedures carry their own risks: burns, post-inflammatory hyperpigmentation — more likely in darker skin — and worsened texture when the protocol is too aggressive for that skin.

That is why structural assessment is part of the process here. The Doppler ultrasound we use before and after filler procedures serves to understand the structure of that face, including material from previous treatments, and to confirm there is no vessel compression. The same principle applies to skin: understand what is there before delivering energy. That is what turns "it's safe" from a promise into a verification.

And it is worth saying the obvious thing nobody says: do not squeeze. At-home extraction ruptures the follicle wall, causes inflammation, and repeated inflammation at the same spot is one of the most efficient ways to make that pore permanently larger.

When we advise against it

• When the expectation is closed pores. That does not exist. Aligning on this beforehand is more honest than delivering a real improvement against an impossible expectation.
• When the skin is in an active flare — inflamed acne, a compromised barrier, irritation from too many actives. The inflammation is treated first; a procedure on irritated skin worsens what it came to correct.
• When the person will not use sunscreen. Without it, stimulated collagen breaks down at the same rate it is produced, and post-procedure pigmentation becomes a real risk.
• When the person wants a single session. Pores respond to a series and to maintenance. One isolated session does not sustain a result.
• Pregnancy and breastfeeding. An elective procedure waits, and many of the actives recommended here are off the table during this period.

Frequently asked questions

Which acid closes pores?

The most direct is salicylic acid, because it is oil-soluble and acts inside the oily channel. For the texture and firmness component, retinoids have a better track record. Neither closes the pore — they reduce apparent diameter with continued use.

What skin type has large pores?

They are most common in oily and combination skin, especially in the T-zone. But dry skin has them too, particularly when the cause is loss of firmness with age. Visible pores are not a diagnosis of oily skin.

Which vitamin closes pores?

Niacinamide, vitamin B3, is the one most often cited, and it helps with oil control and the barrier. It improves appearance. It does not close pores.

How long until I see a difference?

Surface procedures show a change in texture within a few sessions, over a matter of weeks. The collagen approach takes longer, because it depends on what your body has yet to produce. Topical actives need months of consistency. Anyone promising results in a week is talking about swelling and lighting.

Do large pores come back after treatment?

They do, in the sense that the cause remains active: the body keeps producing sebum, and collagen keeps breaking down with time and sun. That is why pores are a maintenance topic, not a treatment with an end date.

Does makeup make pores worse?

Makeup itself, properly removed, does not. What makes things worse is sleeping in it, scrubbing to take it off, and wearing heavy foundation on skin that is already inflamed. A texture-filling primer fixes things on the spot and changes nothing underneath.

Is it worth photographing my pores at home to track progress?

Very much so — as long as you fix the conditions. Same light, same time of day, same distance, no makeup, no filter. It is the best way to know whether what you are doing works, and it is more reliable than memory, which always thinks nothing has changed.
