Botox is an injection of purified botulinum toxin that temporarily relaxes targeted muscles, softening expression wrinkles and slimming overdeveloped muscles. At Yaan Clinic in Gangnam, Seoul, botox treatments use XEOMIN, made by MERZ in Germany, and are planned and injected by doctors who hold MERZ Key Doctor status.

This page is the hub for all botox treatments at Yaan Clinic. It explains how botox works, which areas can be treated, how Yaan plans dosing, and which dedicated page to read next for jawline, skin, lip-corner, gummy-smile or calf treatments.

What is Botox and how does it work?

Botox is a muscle-relaxing injection. A small dose of botulinum toxin blocks the nerve signal that tells a muscle to contract, so the muscle relaxes for a period of months and the wrinkle or bulk it creates softens.

"Botox" is often used as a general name for every botulinum toxin product, much as people say "Kleenex" for tissues. Yaan Clinic uses XEOMIN, a botulinum toxin type A made by MERZ. XEOMIN is known internationally as a purified toxin without the complexing proteins found in some other products. Your doctor will explain which product and dose suit your goals at consultation.

Depending on where it is injected, botox can do three different jobs:

• Relax expression muscles to soften dynamic wrinkles such as forehead lines, frown lines between the brows and crow's feet.
• Slim overdeveloped muscles such as the masseter (jaw) muscle or the calf muscle, for a slimmer jawline or leg line over time.
• Refine the skin when very fine, superficial injections are spread across the face ("skin botox"), which Yaan uses for elasticity, pores and texture.

Why does Yaan Clinic use XEOMIN?

Yaan Clinic uses XEOMIN from MERZ, Germany, as its botulinum toxin and states that it uses genuine products in the correct dosage. Yaan's doctors are Official Key Doctors of MERZ (MERZ Korea), the company that makes XEOMIN.

For patients traveling to Korea, product authenticity and dose matter. A lower price can sometimes reflect a diluted dose or an unverified product. Yaan Clinic's policy is to use the named genuine product at the dose your plan requires. Founder and Chief Doctor Dr. Wontak Choi is listed as a Key Doctor at MERZ. You can read more about how the clinic handles product verification on the genuine products and safety page.

How does Yaan Clinic plan a botox treatment?

Every botox plan at Yaan Clinic starts with an individual analysis of your muscles and expressions to set the injection points and dose. The aim is a natural result that keeps your expressions, not a frozen look.

Muscle strength, face shape and habits differ a lot from person to person. Yaan's site notes that men and women often need different planning, because muscle mass and the desired outcome are different. A typical visit looks like this:

1. Consultation – you explain your goals, and the doctor reviews your medical history, previous treatments and upcoming events.
2. Muscle and expression analysis – the doctor asks you to frown, smile or clench to see how each muscle moves.
3. Dose and point design – injection points and units are set for your face, not a fixed template.
4. Injection – fine-needle injections take a short time; most areas are done within minutes.
5. Aftercare guidance – you receive post-treatment instructions, which matter most in the first period after injection.

How long does botox last?

Botox results are temporary. Effects typically begin within several days, reach their peak around two weeks, and usually last a few months before muscle activity gradually returns. Yaan Clinic does not publish a fixed duration, and your doctor will discuss your expected timeline.

Duration depends on the area, the dose, your muscle strength and your metabolism. Muscle-slimming treatments such as jaw or calf botox work gradually, because the muscle needs time to become less bulky. According to Yaan's FAQ, stopping botox does not make wrinkles worse than they were before treatment; the muscle simply returns to its previous activity.

How much does botox cost at Yaan Clinic in Seoul?

At Yaan Clinic, wrinkle botox costs ₩100,000 with Xeomin or ₩160,000 with Allergan. Jawline botox is ₩170,000 (Xeomin) or ₩350,000 (Allergan), and full-face skin botox is ₩490,000 (Xeomin) or ₩690,000 (Allergan).

Treatment	Xeomin (KRW)	Allergan (KRW)
Wrinkle botox	₩100,000	₩160,000
Jaw (masseter) / salivary gland / temporalis botox	₩170,000	₩350,000

These are Yaan Clinic's guide prices in KRW. International patients pay the same price as Korean patients, and your final price is confirmed at consultation. The consultation fee (₩10,000, or ₩30,000 with a director) is waived if you have a treatment. See Botox price in Seoul, jawline Botox price, skin Botox price and all treatment prices.

Who is a good candidate for botox?

Good candidates are healthy adults bothered by expression lines, a square jaw caused by muscle, a downturned mouth, a gummy smile or muscular calves. Yaan's FAQ notes that preventive botox is possible for people who want to slow the deepening of lines.

Botox is usually not recommended during pregnancy or breastfeeding, or for people with certain neuromuscular conditions. Static wrinkles that remain when your face is relaxed, or lost volume, often respond better to dermal filler or collagen treatments. Your doctor will confirm suitability at consultation.

Botox vs filler: what is the difference?

Botox relaxes muscles to soften movement-related lines and slim muscle bulk, while filler adds volume to fill hollows, folds and static lines. Many patients benefit from both, and Yaan Clinic can combine them in the same visit.

	Botox (XEOMIN)	Hyaluronic acid filler
How it works	Relaxes the targeted muscle	Adds volume under the skin
Best for	Forehead lines, frown lines, crow's feet, square jaw, gummy smile	Hollows, folds, nose and chin shape, lost volume
Onset	Gradual, over days	Visible immediately
Combine?	Yes; Yaan's FAQ confirms filler and botox can be done in the same visit	Yes

For the overall face shape, the non-surgical facial contouring guide explains how botox, filler and threads work together.

What is recovery like after botox?

Recovery after botox is quick. Most people return to normal activities straight away, and Yaan's FAQ confirms that exercise is fine. Follow your doctor's post-treatment instructions, especially in the first period after injection.

Small injection marks or slight redness usually settle within hours. Mild bruising is possible. General advice typically includes not massaging or pressing the treated area on the day of treatment. Your doctor will give you instructions that match the area treated.
