Toxin at skin level

What is skin toxin, and what does it do to pores and shine?

The short answer

Skin toxin is botulinum toxin, diluted and placed as a grid of very small droplets in the upper layer of the skin across the cheeks, nose, forehead or neck. A wrinkle injection goes deeper, into a muscle, to soften a movement. At skin level the target changes: the oil glands and the finest fibres that tug on the surface are quieted, so the face looks less shiny, pore openings can read smaller and crêpey texture looks smoother. Microtoxin and intradermal toxin are other names for the same approach; in Korea it is simply called skin toxin.

Source: Rewind's Korean rate list, which carries skin-level plans for the butterfly zone, the full face, and the face with the neck as three separate items. The action on oil is described from the published study of intradermal injection for oily skin listed at the foot of this page.

The effect is temporary, and it works on oil and surface tone. Pores widened by old acne scarring, by years of sun or by a cheek that has started to loosen keep their shape, and the examination is where that is sorted out before any plan is written. The muscle-level uses of the same medicine are set out on the main botulinum toxin page.

Coverage

Which parts of the face does a skin toxin plan cover?

Rewind lists skin-level work in three sizes, and the choice between them follows where the oil and the visible pores actually sit. Most people who come in about pores turn out to have a central problem, so the smallest plan is often where a first session starts.

zone 01
Butterfly zone
The cheeks either side of the nose and across its bridge, a shape that looks roughly like a pair of wings. Pores tend to be largest here, and the smallest listed plan is aimed at it.
zone 02
Full face
Forehead, nose, cheeks and chin in one session. Chosen when shine runs across the T-zone and up the forehead, where treating the centre alone would leave an obvious edge.
zone 03
Face and neck
The full-face plan continued down the neck, where fine crêpe-like texture usually bothers patients more than oil does.
zone 04
Around the mouth
The skin over the smile muscles is approached with particular care, or left out of the map, because a droplet that drifts into muscle there is felt in expression.
Grid

Mapping the droplets

How is a microdroplet skin toxin plan laid out?

Three decisions shape the session: which zone is covered, how finely the dose is spread across it, and how close to the surface each droplet sits. The total amount of medicine is small. The skill lies in its distribution.

01Sort

Oil, pore shape and texture are read separately

The T-zone, cheeks and neck are examined for shine, for the size and outline of each pore opening, and for fine surface lines. Round, oily openings in firm skin behave very differently from openings stretched into teardrops along a cheek that has started to soften. The first group is what this injection is for.

02Spread

Many shallow points across the zone

A muscle plan uses a handful of injection points. A skin plan uses many, spaced evenly over the chosen zone, each carrying a small share of a diluted dose. Spreading it this way keeps the effect even across the surface and means no single spot receives very much.

03Depth

Each droplet is meant to stay in the dermis

The oil glands sit in the skin itself, so that is where the droplets belong. Placed too deep, the same medicine can reach the thin facial muscles that shape a smile. The map is therefore drawn with the expression muscles marked out first, and the grid is built around them.

04Evidence

What the published research on skin-level toxin covers

A 2013 clinical paper examined the safety and efficacy of intradermal toxin for oily skin, and a randomised trial in underarm sweating shows the same medicine acting on glands within the skin. Work measuring pore size by itself is thinner, and this page claims no more than those studies describe.

Why here

Why have oily skin and open pores assessed by a plastic surgeon?

An enlarged pore is a symptom with several causes. A skin-level injection answers one of them, and the useful part of a consultation is hearing which cause you have before anything is drawn up.

01Cause

One examination separates oil from structure

Dr. Choi looks at the skin with the face still and then moving. Shine and round openings over firm skin point to oil. Openings pulled downward along the cheek point to support that has begun to give way, which is a lifting question, and one he also treats.

02Expression

A smile is protected by where the droplets go

Because his surgical work involves the facial muscles directly, the medical director knows where a stray droplet would show in a smile, and he keeps the skin grid clear of those zones from the first session.

03Interval

The second session is timed from the first

The zone used, how the skin felt after a fortnight and the week the shine came back are kept on your chart. Patients living abroad can send that by message in their own language, so the next visit is booked against a real interval.

Appointments run on Monday, Tuesday, Wednesday and Friday from 10:00 to 19:00 and on Saturday from 10:00 to 16:00; the clinic is closed on Thursday and Sunday. Your skin is cleansed, the medical director confirms the zone agreed at the examination, the droplets are placed across it, and the rest of the day is yours. Small raised points where the needle went in flatten on their own.

Skin-level work has no published anaesthesia protocol or session length at Rewind, so neither figure appears on this page. Mention any toxin, filler or skin booster placed in the same zones over recent months, including anything done outside Korea.

Rates

Coverage and cost

Skin toxin prices in Gangnam: butterfly zone, full face, face and neck

Skin-level plans are priced by coverage, from the smallest zone to the widest. Each plan has one fixed figure; the examination decides which of the three matches the spread of oil and pores on your face.

Butterfly zoneCentral cheeks and nose, the usual first plan for pores
₩200,000
Full faceForehead, nose, cheeks and chin in one session
₩250,000
Full face and neckThe full-face grid continued down the neck
₩300,000

Each skin plan is shown before value-added tax, which is added when you pay; an anaesthetic fee, where one applies, sits inside the figure. Because the effect fades, the useful comparison is what a year of sessions costs at the interval your own skin needs. Visits that pair a hydration vial with a butterfly-zone dose are listed with the skin boosters.

Suitability

Whose pores respond to skin toxin, and whose need something else?

Often a good match

  • Shine across the T-zone that is back within hours of washing
  • Round, visible pore openings on the nose and central cheeks in skin that still feels firm
  • Foundation that slides or separates by the middle of the day
  • Fine surface texture on the cheeks or neck you would like smoother for an event or a season

Talked through at the examination first

  • Pores that follow old acne scarring, where the shape is structural and RF microneedling is usually the more relevant conversation
  • Dry or easily irritated skin, which can feel tight and flaky once its oil is reduced further
  • Openings stretched downward along a softening cheek, a sign of lost support that oil control will not touch
  • Pregnancy, breastfeeding, a neuromuscular disorder, active infection in the zone, or toxin given to the same area within recent months

The treatment is declined when the examination finds pores shaped by scarring or laxity and the patient is hoping the injection will change them. It will not, and the doctor explains at the same visit which treatment addresses the cause and what it would involve.

After

The weeks after

What does skin look like in the weeks after a microdroplet session?

Rewind's written aftercare is brief and covers all of its toxin injections. The rest of this timeline describes what patients generally notice, and your own version of it is what sets the date of the next session.

Same day
Small raised points
The injection points can show as tiny bumps or pinprick marks. They settle without treatment, and normal activity carries on.
Day 1–2
No pressure, no heat
Keep massage tools and firm pressure off the treated zone, and for the first day or two skip heavy drinking and hot, humid rooms such as saunas.
Week 1–3
Judge it in your own light
Any change in oil and in how the pores read is assessed once the effect has settled, in the mirror and lighting you normally use, at the same time of day.
Month 3–6
The shine returns
Rewind states an effect of three to six months across its toxin treatments. Note the week your skin starts to feel oily again; that date is what the next plan is built on.

Reported effects of toxin placed in the skin include pinpoint bleeding and bruising, redness and swelling at the injection points, a temporary feeling of tightness or dryness, and, if the medicine spreads into the facial muscles, a smile that looks uneven until the effect fades. Report any change in expression early, so it is recorded and the next map leaves that zone out.

Questions

Skin toxin for pores and oil — what people ask before booking

What is skin toxin, and how is it different from an injection for wrinkles?
Both use botulinum toxin. A wrinkle injection places a few doses into a muscle to soften a movement. Skin toxin spreads a diluted dose as many tiny droplets in the upper skin, where it acts on oil glands and surface texture, and expression is meant to stay as it was. Microtoxin and intradermal toxin are other names for it.
How much does full-face skin toxin cost at Rewind in Gangnam, Seoul?
The full-face plan is listed at ₩250,000. The smaller butterfly-zone plan is ₩200,000, and the face-and-neck plan is ₩300,000. Each is shown before value-added tax, with no separate anaesthetic charge on top. The examination decides which coverage you need.
How often does skin toxin need repeating to keep oil and pores in check?
Rewind's published figure for its toxin injections is three to six months, and a skin-level plan is repeated when your own shine returns somewhere inside that window. Coming back sooner stacks medicine on skin that is still responding, so the date of the next session is taken from your chart.
Do pores stay smaller once the effect wears off?
They drift back. As the oil glands recover, shine returns and the openings gradually look as they did before, so the change lasts only while the plan is repeated. Pores enlarged by scarring or by loosening skin respond little at all, and the doctor will tell you if yours belong to that group.
Could skin toxin change the way I smile?
It can, if droplets spread from the skin into the thin muscles around the cheeks and mouth. The change is temporary but noticeable, and it fades on the same schedule as the rest of the effect. For that reason the map keeps skin-level work clear of the smile muscles, and any unevenness should be reported early.
Is the butterfly zone enough, or should the whole face be treated?
That depends on where the oil and open pores are. When they sit on the nose and central cheeks, the butterfly zone is often enough and costs least. Shine that also covers the forehead and chin usually calls for the full-face plan, so the treated area does not stop at a visible border.
Will there be visible marks when I leave the clinic?
Often a few. Tiny raised points appear where the droplets entered and flatten on their own, and pinprick bruises can show where the skin is thin. Most patients carry on with their day. If photographs or an event are planned, leave a few days between the session and that date.
When is RF microneedling a better choice than skin toxin for pores?
When the pores are shaped by old acne scarring, rough texture or loss of firmness. Skin toxin works on oil and surface tone for a few months at a time; radiofrequency microneedling works on the structure of the skin itself. Some plans use both, sequenced by the doctor after the examination.

Scientific evidence

Published work on toxin placed in the skin

Together these papers cover toxin injected into the skin for oiliness, a controlled trial of its action on sweat glands, consensus guidance on facial dosing, the pharmacology that ties a unit to its own preparation, and pooled safety data from aesthetic use. None of them was carried out at Rewind, and none can say how a particular skin will respond to a particular plan.
