Botox (botulinum toxin) is an injection treatment that temporarily reduces the nerve signals that make muscles move.

Botox
Non-surgical cosmetic treatment · Botox
Botox is a prescription medicine made from a purified protein toxin produced by the bacterium Clostridium botulinum. It blocks the transmission of a nerve substance and paralyzes movement for a period of time, which reduces the movement of expression muscles and helps improve wrinkles. The dose varies with the area treated, and effects such as reduced muscle size and softer wrinkles can be expected (results vary). DM Dermatology's principle is to use genuine products in the specified amounts.
DM Dermatology divides Botox into five uses: Wrinkle Botox for expression lines (forehead, glabella, crow’s feet, mouth corners, chin), Contour Botox for the facial outline (square jaw, salivary glands, nostrils), Body Botox for body muscles (trapezius, calves, thighs), Skin Botox, which places small amounts in the shallow skin layer (jawline, neck, full face), and Hyperhidrosis Botox to reduce sweating (underarms, palms, soles). Areas other than glabellar lines and crow’s feet (and forehead lines for some products) are off-label uses, so the doctor decides after an examination.
The effect of the medicine fades gradually over several months. That is why we plan the areas, the dose, and the timing of your next treatment together. At DM Dermatology in Apgujeong, we first examine your expressions, muscles, and skin, then choose the method.

TREATMENT AREA
Face and body:
Botox treatment areas
Botox acts on the muscles near the injection site. So we first check the expressions and muscles that concern you, then set the injection points and dose for each area separately.
DM Dermatology treats the forehead, glabella, crow’s feet, mouth corners, chin, square jaw, salivary glands and nostrils on the face; the jawline, neck and full face with Skin Botox; the trapezius, calves and thighs on the body; and hyperhidrosis (underarms, palms, soles). Other areas are decided after a consultation.
- Trapezius — the line above the shoulders
- Calves · thighs — developed leg muscles
- Hyperhidrosis — underarms · palms · soles

- 1
Forehead Horizontal lines that form when you raise your eyebrows. Treatment reduces the movement of the forehead muscle.
- 2
Glabella Vertical lines that form when you frown. Treatment reduces the movement of the muscles between the eyebrows.
- 3
Eye area Fine lines at the outer corners of the eyes when you smile (crow's feet). Injections go into the outer part of the muscle around the eye.
- 4
Square jaw An angular jawline from a well-developed masseter, the muscle that clenches the back teeth. Treatment reduces the muscle's volume. If bone shape is the main cause, the change is small.
- 5
Salivary glands Used when enlarged salivary glands in front of and below the ears (parotid glands) make the lower face look wide.
- 6
Jawline Skin Botox reduces the pull of shallow muscle fibers below the jawline to neaten its outline.
SPECIAL
Short injection time, careful planning
What's special about DM Botox
There are several Botox products, and how long results last depends on the product, area, and dose. For wrinkle areas, it is generally about 3–4 months.
Genuine products, set doses
We use genuine products in the specified amounts. We go over the product and the dose for each area with you during the consultation.
Side-effect checks and guidance
Before treatment, we check your current medications, medical history, and the dates of past treatments. We set the injection depth and points for each area and explain possible side effects and how to handle them in advance.
Personalized design
Even among square jaws, muscle thickness and left–right differences vary. We watch your expressions and feel the muscles, then set the areas and doses separately.
HOW IT WORKS
How it works: giving the signal
to the muscle a short rest
Muscles move when they receive a signaling substance (acetylcholine) released from nerve endings. Botulinum toxin blocks the release of this substance from the nerve endings. As a result, the injected muscle becomes weaker, and the wrinkles that muscle formed, or the muscle's volume, decrease.
Over time, the nerves grow new branches and pass on signals again. That is why muscle movement gradually returns over several months. Skin Botox uses the same medicine, diluted, and places very small amounts spread through the shallow layer of the skin.
- When changes show
In wrinkle areas, changes usually begin within 2–7 days and become clear at around 2 weeks. Muscle volume decreases over several weeks.
- Muscle Botox
Injected into muscles such as the expression muscles or the masseter to reduce their movement and volume.
- Skin Botox
Injected shallowly, near the dermis, it acts on fine muscle fibers in the skin and around the sweat and oil glands.

- 1
Epidermis The outermost layer of the skin.
- 2
Dermis · Skin Botox Skin Botox places very small amounts spread through this layer.
- 3
Sweat · oil glands Nearby structures that Skin Botox acts on. They are involved in producing sweat and sebum.
- 4
Expression muscle Botox is injected into the muscles that form wrinkles.
- 5
Nerve ending The medicine blocks the release of the signaling substance, so the muscle rests.
BY PURPOSE
DM Botox
by purpose
DM Dermatology divides Botox into five uses. Choose the use that matches your concern below to go straight to it.

01Wrinkle
Wrinkle Botox
Used for lines that form with facial expressions, such as on the forehead, glabella and crow’s feet, and for concerns caused by the pull of expression muscles, such as the mouth corners and chin. Small amounts are injected into the expression muscles to reduce their movement.
Lines usually start to soften within 2–7 days, look clearly different at around 2 weeks, and the effect lasts about 3–4 months.
1ForeheadForehead
The horizontal lines that form when you raise your eyebrows. We spread small, even amounts across the frontalis, the muscle that covers the whole forehead.
Because the frontalis lifts the eyebrows, the amount near the brows is usually reduced so they do not look heavy.
2GlabellaGlabella
The vertical lines between the eyebrows. We inject small amounts into the muscles that pull the brows inward and down when you frown (corrugator and procerus).
Before treatment, we check your eyebrow height and usual facial expressions.
3Eye areaCrow's feet
The fan-shaped lines at the outer corners of the eyes when you smile. We inject small, shallow amounts into the outer part of the ring-shaped muscle around the eye (orbicularis oculi).
We avoid the area just under the eye and adjust the amount so your smile stays natural.
4Mouth cornersMouth corners
The muscle below and outside the mouth corners that pulls them down (depressor anguli oris). A very small amount is injected into this muscle to address mouth corners that look droopy.
Too much or a slightly wrong spot can make your mouth look unnatural when you talk or smile, so we start with a small amount.
5ChinChin
A “pebbled” chin, where the chin skin dimples when you close your mouth. Small amounts are injected into the chin muscle (mentalis) to ease its tension.
It lies close to the muscles that move the lips, so we adjust the amount and spots so lip movement is not affected.
- You notice fine lines at the corners of your eyes when you smile
- Vertical lines between your brows deepen when you frown
- You notice horizontal forehead lines when you raise your brows
- Those whose mouth corners look droopy or whose chin dimples
- You want to care for expression lines before they set in

02Contour
Contour Botox
Used for the square jaw, salivary glands and nostrils. For the square jaw, it is injected into the masseter (the muscle that clenches the back teeth); for the salivary glands, into the parotid glands in front of and below the ears, reducing their volume to address the lower facial line. For the nostrils, it is injected into the small muscles that widen them.
A square jaw changes gradually from 2–4 weeks, looks clearly different at around 3 months, and sometimes lasts 6 months or longer. If bone shape is the main cause, the change is small.
6Square jawMasseter
The masseter, the chewing muscle that bulges firmly at the corner of the jaw when you clench your back teeth. We feel the thickness of the muscle and inject small amounts into it.
Changes appear gradually from 2–4 weeks, and they are smaller if the bone shape is the main cause.
7Salivary glandsParotid gland
The salivary gland in front of and below the ear (parotid gland). When an enlarged gland makes the lower face look wide, the aim is to reduce its volume by injecting into the gland.
At the examination, we first check whether the width comes from the salivary gland or the jaw muscle.
8NostrilsNostrils
Where the nostrils flare out when you smile or breathe deeply. A small amount is injected into the small muscles that widen the nostrils to address nostrils that look spread out.
If the cartilage or skin shape of the nostrils is wide in itself, the change is small, so we check this at the examination first.
- The corners of your jaw bulge firmly when you clench your back teeth
- Fullness below the ears makes your lower face look wide
- Those whose nostrils spread out when they smile

03Body
Body Botox
Used for developed body muscles such as the trapezius, calves and thighs. It reduces muscle strength and volume to address the line from the neck to the shoulders and the leg line.
Body muscles are larger than facial muscles, so changes appear slowly. When fat is what makes an area look thick, the change is small, so we first check whether the cause is muscle or fat.
9TrapeziusTrapezius
The upper part of the muscle that runs from the neck to the shoulders. When it is well developed, the tops of the shoulders rise and the neck looks shorter. We inject small amounts into the muscle on top of the shoulders.
For a few weeks after treatment, your shoulders may feel weaker when you lift heavy things.
10ThighsThigh
When the thighs look thick because of exercise or naturally large muscles, small amounts are injected into the developed thigh muscles.
These are large muscles used for walking and climbing stairs, so the area and amount are set at the examination so daily life is not affected. If fat is the cause, we also discuss body contouring.
11CalvesCalf
The gastrocnemius at the back of the calf. We inject small amounts into the muscle that bulges firmly when you stand on tiptoe.
Your legs may feel tired when you walk for a long time or climb stairs, so we first ask about your activity level and daily habits.
- The back of your calves bulges firmly when you stand on tiptoe
- Raised upper shoulders make your neck look short
- You notice the line when wearing skirts or off-shoulder clothes
- Those whose legs look thick because exercise has developed their thigh muscles

04Skin Botox
Skin Botox
Diluted Botox is injected in small, closely spaced amounts into the shallow skin layer. For the jawline, it eases the pull of the shallow muscle fibers below the jaw to define the border; for the neck, it addresses horizontal fine lines; and for the full face, it addresses fine lines, oiliness and pores that look large.
Changes usually show from about 1 week, are clear at around 4 weeks, and last about 3 months. With significant sagging or deep wrinkles, we also discuss lifting or filler.
12JawlineJawline
Below the jawline and the upper neck. Diluted product is injected closely into the thin muscle fibers just under the skin (platysma), aiming to reduce their downward pull.
If sagging is significant, we also discuss lifting.
13NeckNeck
Horizontal fine lines on the neck. Diluted product is injected in closely spaced amounts into the shallow layer of the neck skin.
For deep neck lines, we also discuss fillers or other treatments.
14Full faceFull face
Very small amounts are injected closely into the shallow layer of skin (dermis) across the whole face.
It addresses fine lines, oiliness, and pores that look large. For deep wrinkles, we also discuss fillers.
- The border between your jaw and upper neck looks blurred
- Those bothered by horizontal fine lines on the neck
- You are bothered by fine lines and shine across the face
- You want to work on skin texture rather than reduce muscle much

05Hyperhidrosis
Hyperhidrosis Botox
Used where sweating is excessive, such as the underarms, palms and soles. The aim is to reduce sweating by reducing the nerve signals to the sweat glands. At the examination, we also check whether another condition is causing the sweating.
Sweating usually starts to decrease within a week, and the change often lasts around 6 months. The duration varies by person and area.
15UnderarmsUnderarm
Small, closely spaced amounts are injected into the sweat-gland layer of the underarm skin, aiming to reduce sweating.
The area to inject is set by checking where you sweat.
16PalmsPalm
Small amounts are injected across the palm skin. The palms are sensitive and injections there tend to hurt more, so we also decide how to reduce the pain.
Your hands may feel slightly weaker for a while after treatment. Treatment of the soles is decided after a consultation.
- Those whose underarm sweat leaves marks on their clothes
- Those whose sweaty hands make handshakes or writing uncomfortable
- Those whose sweating makes every summer uncomfortable
Areas other than glabellar lines and crow’s feet (and forehead lines for some products) are off-label uses, so the doctor decides after an examination. For hyperhidrosis, approved uses differ by product, so we check the product before treatment. Other areas are decided after a consultation.

| When changes show | From 2–7 days; clear at around 2 weeks | Square jaw: from 2–4 weeks, clearer at about 3 months | Gradually over several weeks | From about 1 week; clear at around 4 weeks | Usually within 1 week |
| Duration | About 3–4 months | Square jaw: sometimes 6 months or longer | Depends on muscle strength | About 3 months | Around 6 months |
| Interval to next treatment | 3 months or more | 3 months or more | 3 months or more | 3 months or more | 3 months or more |
These are typical ranges. They vary from person to person with the dose, area, and muscle strength.
ADVANTAGE
Key features of DM Botox!
STEP 01
Procedure time: 5–10 min
The injections themselves are quick. If numbing cream is used, applying it and waiting takes extra time.
STEP 02
Cold pack or numbing cream for comfort
It is often done without numbing. To reduce the sting, we use a cold pack or numbing cream. How much you feel varies by area and person.
STEP 03
Preparing to reduce bruising
Blood-thinning medicines such as aspirin and anti-inflammatory painkillers can increase bruising. Do not stop any medicine on your own; tell us about it before treatment.
STEP 04
An injection treatment without incisions
It is done with a fine needle, and the skin is not cut. Small red marks or bruises at injection sites usually settle within a few days.
STEP 05
A relatively quick return to daily life
You can wash your face and wear makeup on the day of treatment. Do not lie down for 4 hours, and skip saunas and intense exercise for 1 week.

PROCESS
DM Botox
treatment process
Below is the general flow. The actual steps and timing vary by area.
01Consultation and examination
We check your wrinkles and muscles as you make different expressions. We ask about your current medications, medical history, pregnancy or breastfeeding, and the dates of recent treatments.
02Mapping the areas
We mark the injection points on the skin with small dots. We also look at differences between the left and right muscles.
03Cold pack · numbing cream
After cleansing and disinfecting the skin, we reduce the sting with a cold pack or numbing cream if needed.
04Injection
Using a fine needle, we divide the set dose among the marked points. Injection takes about 5–10 minutes.
05Check and go home
We check the injection sites and cool them to soothe the skin. Do not lie down for 4 hours; stay seated or standing.

Caution
DM Botox
aftercare precautions
While the medicine settles in, do not press or rub the treated area.
- 01Swelling · bruising
Mild swelling or bruising may occur at injection sites, but it fades naturally over time.
- 02Avoid extreme heat and cold
Keep the treated area away from extreme heat or cold, and avoid massage, saunas, and intense exercise for about a week.
- 03No lying down for 4 hours
Do not lie down for 4 hours after treatment.
- 04Visit us if symptoms persist
If pain or redness at injection sites lasts more than a day, please visit the clinic.
- 05No pressing or rubbing
On the day of treatment, do not press hard on or rub the injection sites. For a few days, also avoid sleeping face down and using facial massage devices.
- 06Skip alcohol
Alcohol can increase bruising and swelling, so it is a good idea to skip it on the day of treatment and the next day.
- Pain, redness, swelling, or bruising may occur at injection sites. These usually settle within a few days, and bruises fade over 1–2 weeks. Headaches can also occur.
- If the medicine spreads to nearby muscles, the eyelids or eyebrows may droop, the forehead may feel heavy, or the eyebrow shape may change. These usually return to normal as the medicine's effect wears off.
- Left–right asymmetry or unnatural expressions may occur. Check the change at around 2 weeks, then talk with our medical staff.
- After square-jaw Botox, you may have less strength when chewing tough food, or the corners of your mouth may look different when you smile. After salivary gland Botox, less saliva may leave your mouth dry.
- After trapezius Botox, your shoulders and neck may feel weak, or you may tire easily when lifting heavy things. After calf Botox, your calves may feel weaker when you walk for a long time or climb stairs.
- With Skin Botox, if the medicine spreads into deeper muscles, your smile may look unnatural or your neck may feel weak. This usually settles within 2–3 weeks.
- Rarely, the effect of the medicine can spread beyond the injection site. If, within hours to weeks after treatment, you have general muscle weakness, double or blurred vision, a hoarse voice, or trouble speaking, swallowing, or breathing, contact a hospital right away and get medical care.
- Rarely, allergic reactions such as hives, swelling of the face or neck, or shortness of breath may occur.
- Treatment is not given if you are hypersensitive to any ingredient of the medicine, have an infection or inflammation at the injection site, or have a neuromuscular disease such as myasthenia gravis, Lambert-Eaton syndrome, or amyotrophic lateral sclerosis (ALS). Treatment is also not given if you are pregnant, may be pregnant, or are breastfeeding.
- Be sure to tell us before treatment if you use aminoglycoside antibiotics or muscle relaxants, have ever had trouble swallowing or breathing, bleed easily or take anticoagulants, or recently had Botox elsewhere.
- If repeated treatments lead your body to form antibodies to this medicine, its effect may weaken. To lower this risk, we use only the amount needed, at intervals of at least 3 months.
- Each product has its own approved uses. In Korea, the approved cosmetic uses are glabellar lines and crow’s feet (forehead lines for some products). Mouth corners, chin, nostrils, square jaw, salivary glands, trapezius, calves, thighs and Skin Botox are not approved uses; the doctor decides after an examination. For hyperhidrosis, approved uses differ by product, so we check whether the product we use is approved before treatment.
- Results, duration, and side effects vary from person to person.
※ Bruising and swelling may occur after a procedure or surgery, depending on the person.

FAQ
01How long does Botox last?
It depends on the area and the person. Forehead, glabellar and crow’s-feet lines usually last 3–4 months. For the square jaw, the reduced muscle volume can last 6 months or more. Skin Botox usually lasts about 3 months, and hyperhidrosis Botox often lasts around 6 months.
02How soon will I see results after Botox?
In wrinkle areas, movement usually starts to decrease within 2–7 days, and the change becomes clear at around 2 weeks. At around 2 weeks, it is a good idea to check your left–right balance and expressions in a mirror.
03When will I see results from square-jaw Botox?
For the square jaw, change shows only as the muscle shrinks, so it takes longer than for wrinkles. The jaw angle usually starts to change gradually from 2–4 weeks, and the change is clear at around 3 months. After that, the muscle slowly returns to its original size.
04How is Skin Botox different from Botox?
They use the same medicine, but the injection depth and amount differ. Botox is injected into muscle to reduce its movement or volume. Skin Botox places diluted medicine closely through the dermis, aiming at changes in fine lines, sebum, and the jawline border. Neither one is better; the right method depends on your concern.
05Can I build up resistance if I get Botox often?
If repeated treatments lead your body to form antibodies to this medicine, its effect may weaken. To lower this risk, only the amount needed is given, at intervals of at least 3 months. Please also tell us the dates and areas of any treatments you had at other clinics.
06When can I exercise or use a sauna after Botox?
Avoid saunas, massage, and intense exercise for about a week. This keeps heat and pressure away from the treated area. Everyday activities such as light walking are fine.
07Can I lie down right after Botox?
Do not lie down for 4 hours after treatment. This keeps the injection sites from being pressed or rubbed. On the day of treatment, do not rub or massage the injection sites hard.
08Can I drink alcohol after Botox?
Alcohol widens blood vessels and can increase bruising and swelling. We recommend not drinking on the day of treatment and the next day. If you have a bruise, it is a good idea to avoid alcohol until it fades.
09How are Xeomin and Botulax different?
Both are botulinum toxin type A. Xeomin is made by Merz in Germany and Botulax by Hugel in Korea, and they differ in purification method and added ingredients. Units differ in strength from product to product, so a dose of one cannot be swapped one-for-one with the other. We decide together in the consultation, based on the area and your past treatments.
10Who will I see for a Botox consultation at DM Dermatology in Apgujeong?
DM Dermatology is a dermatology clinic where Dr. Shin Young-ik, Medical Director and board-certified dermatologist, sees patients. After checking your wrinkles, muscles, skin, and medical history in an examination, the doctor chooses the right method (Botox or Skin Botox), the areas, and the dose.
