Gangnam underarm Botox for concerns about sweat and odor

July 1, 2026

Hello.

I am Director Jung-Hwang Information of Cleor Clinic Gangnam Branch.

Have you ever had the experience of having to worry about your clothing color regardless of the season due to underarm sweat,

or feeling cautious about your posture in crowded places?

"I want to wear light-colored shirts or dresses, but I'm hesitant because I'm afraid the clothes will get wet.

I can't even lift my arms comfortably during meetings or presentations."

Underarm sweat is not just caused by heat.

Eccrine sweat glands are concentrated in the underarm area,

and as the sympathetic nervous system of the autonomic nervous system controls these sweat glands,

an environment is created where the amount of sweat secretion varies significantly depending on tension, stress, and temperature changes.

In particular, for those with a tendency toward hyperhidrosis, sweat secretion proceeds excessively even under the same conditions,

making it a category that affects daily life and interpersonal relationships.

Gangnam underarm Botox is a method that acts precisely on these sweating signals.

Today, I will summarize how Gangnam underarm Botox works,

what the difference is between the 100-unit and 200-unit options,

and how toxin lines like Xeomin and Allergan differ.

What is Gangnam underarm Botox?

👉 Gangnam underarm Botox is a hyperhidrosis care procedure that precisely injects botulinum toxin type A into the sympathetic nerve endings that control underarm sweat glands to block acetylcholine secretion for a certain period.

The core of its action is blocking nerve terminal signals.

Sweat glands are structured to be activated when the sympathetic nervous system of the autonomic nervous system secretes a neurotransmitter called acetylcholine,

and botulinum toxin is an ingredient that blocks this acetylcholine secretion itself for a certain period.

It is not a procedure that removes the sweat glands themselves, but rather a method that manages only the sweating signals,

so it is a category where sweat secretion resumes as nerve function recovers after a certain period.

It is known as a medically proven line as it is a procedure area with official indications for underarm hyperhidrosis (primary axillary hyperhidrosis) from both the Ministry of Food and Drug Safety and the US FDA.

Mechanism of Gangnam underarm Botox

👉 Gangnam underarm Botox is summarized by four action structures: blocking nerve terminal acetylcholine secretion, multi-point shallow layer injection, immediate action regardless of growth cycle,

and nerve recovery after time passes.

Blocking nerve terminal acetylcholine secretion

When botulinum toxin type A binds to sympathetic nerve endings,

the process of acetylcholine secretion is blocked for a certain period.

It is an action structure where sweating itself decreases as signals do not reach the sweat glands.

Multi-point shallow layer injection

  • Since sweat glands are concentrated in the upper layer of the dermis,

it is a procedure method injected finely in shallow layers across the entire underarm area.

Instead of injecting into one spot, it is a method of precisely dividing it into multiple points,

so it is a line that acts evenly over the entire underarm area.

  • Immediate action regardless of growth cycle

Unlike laser hair removal, there is no need to wait for the hair cycle.

A decrease in sweating begins to be felt about 3 to 7 days after the procedure,

and it is an action structure where the greatest change is reported at about 2 weeks.

Nerve recovery after time passes

  • The blocked nerve endings recover their function as new nerve branches form over time.

Generally, as the sweating signal resumes between 4 to 9 months,

it is classified as a cumulative care category where additional procedures are recommended.

Effects and advantages of underarm Botox

  • 👉 The core advantages of Gangnam underarm Botox are summarized into three: approaching the sweating signal itself, feeling daily life improvement, and a line with low burden of non-surgical recovery.

First, it approaches the sweating signal itself.

Since it is a method of managing nerve transmission rather than the sweat glands themselves,

it is reported that the amount of sweat secretion itself decreases.

Next, it is a line with significant daily life improvement.

Daily burdens such as clothes getting wet, odor, and being cautious about posture due to sweaty hands

are known to be resolved from about 2 weeks after the procedure.

Finally, it is a non-surgical procedure, so the recovery burden is low.

Since it is a line performed with fine injections without incisions,

it is reported that the procedure time is short and daily activities are possible from the day of the procedure.

Comparison of toxin lines at the Gangnam branch

— Why is pure toxin often recommended for underarm Botox?

👉 Underarm Botox uses more units than facial Botox and is an area with a high frequency of repeated procedures,

so pure toxin lines, which are known to have a relatively lower possibility of resistance even with repeated procedures, are often recommended.

At the Gangnam branch, we operate underarm Botox with 4 types of toxin lines: domestic, domestic premium, Xeomin, and Allergan.

Domestic line

Domestic general is a cost-effective domestic toxin,

and domestic premium is a domestic line that has additionally received US FDA approval.

It is an option recommended for those who want to start the procedure while reducing the burden.Xeomin (Merz, Germany)

Xeomin is a line with the ingredient name incobotulinumtoxin A.

It is a structure containing only 150kDa pure neurotoxin protein from which complex proteins have been completely removed from the botulinum toxin neurotoxin,

  • so it is a category known to have relatively low immunogenicity and a relatively low possibility of resistance even with repeated procedures.

It is a line recommended from a long-term stability perspective in areas where many units are used and repeated procedures occur, such as underarm Botox.

Allergan (The original US Botox)

Allergan is the original line of botulinum toxin type A that received the first FDA approval in the US in 1989.

  • Since it is the area that has been used the longest in clinical practice and has abundant data,

it is an option recommended for those who want to prioritize a perspective based on proven clinical data.

The line that suits your degree of hyperhidrosis and repeated procedure plan will be examined together during the preliminary consultation.

Hyperhidrosis Botox lineup

👉 At the Gangnam branch, we operate underarm Botox with 4 types of toxins × 100 units and 200 units, two options.

100 units are recommended when the amount of sweating is relatively moderate or when you want to check the feeling of the procedure first,

and 200 units are recommended when the amount of sweating is high or when you want to have stable care over a wide area.

  • The combination that suits your degree of hyperhidrosis and toxin preference will be examined together during the preliminary consultation.

Procedures suitable for these people

Those who have excessive underarm sweat regardless of the season

Those who find it difficult to wear light-colored clothes comfortably

Those who become cautious about arm posture in places like meetings, presentations, or dates

Those who are concerned about underarm sweat odor

Those who want to have management every season through repeated cumulative care

Side effects and points to know in advance

👉 Gangnam underarm Botox is a line with relatively proven safety,

but since it is an area where repeated procedures occur, it is good to understand the possibility of resistance management and side effects in advance.

Light redness, fine bruising, swelling, and stinging may accompany the procedure area immediately after the procedure.

Most are reported to subside naturally within a few days.

  • Rarely, a case where the sensation in the procedure area is temporarily slightly dulled is reported,

  • and it is an area that recovers naturally over time.

  • There are rare cases of compensatory sweating (a pattern where sweat increases in other areas) being reported.

  • The incidence rate is known to be relatively low in procedures in the underarm area,

  • and if it is severely accompanied, it is a category where response through medical treatment is recommended.

Since the possibility of resistance is reported in some cases during repeated procedures,

pure toxin lines from which complex proteins have been removed are sometimes recommended from a stability perspective when undergoing long-term repeated care.

Please let us know in advance as the procedure may be restricted in the following cases.

If you are pregnant or breastfeeding

If you have a history of allergies or hypersensitivity reactions to botulinum toxin ingredients

If you have been diagnosed with neuromuscular diseases such as myasthenia gravis

If you are taking medications that affect toxin action, such as antibiotics (aminoglycoside class)

If there is an active infection in the procedure area

⚠️ Precautions before and after the procedure

👉 Management by time point before and after the procedure affects the stability of the effect and the possibility of side effects for underarm Botox.

❓ Frequently Asked Questions (FAQ)

Q. When does the effect of underarm Botox appear?

A decrease in the amount of sweating begins to be felt from about 3 to 7 days after the procedure,

and the greatest change is reported at about 2 weeks.

  • It is an area where there is a difference in the time of expression depending on individual constitution.

  • Q. How long does the maintenance period last?

  • It generally lasts for about 4 to 9 months.

  • There are individual differences depending on individual metabolic rate, amount of sweating, and procedure dosage,

  • and those whose sweat worsens depending on the season sometimes look into the procedure in advance before summer.

Q. How should I choose between 100 units and 200 units?

It is an area determined according to the amount of sweating and the underarm area.

100 units are recommended when the amount of sweating is relatively moderate or when you want to check the feeling of the procedure first,

and 200 units are recommended when the amount of sweating is high or when you want to have stable care.

Q. Which one should I choose between Xeomin and Allergan?

Since both lines are proven botulinum toxin type A lines that have received US FDA approval,

it is an area where it is difficult to determine superiority.

Xeomin is a pure toxin from which complex proteins have been removed,

so it is a line known to have a relatively low possibility of resistance,

and Allergan is the original line with the most abundant clinical data.

In the underarm Botox area where repeated procedures occur,

Xeomin is sometimes recommended from the perspective of resistance management.

Q. How much is the pain?

Since it is a method injected by dividing it into small amounts at multiple points with a fine needle,

it is reported as a degree where stinging stimulation is repeated several times.

It is a composition that reduces the burden of pain with local anesthetic cream application or ice packs before the procedure.

Q. Doesn't sweat increase in other areas?

There are rare cases of a pattern called compensatory sweating being reported.

It is known that the incidence rate is relatively low in procedures in the underarm area,

and it is an area where response through medical treatment is recommended if it is severely accompanied.

Q. Does underarm odor (bromhidrosis) also improve?

Since underarm odor is an area originating from apocrine sweat glands and bacterial metabolism,

it is difficult to completely solve the odor with only Botox that reduces eccrine sweat gland sweating.

However, as sweat secretion itself decreases, the bacterial growth environment is alleviated,

so it is a category where odor reduction is sometimes reported together.

Underarm hyperhidrosis is not a simple constitution, but a multi-factor change where autonomic nervous system control and sweat gland activity act together.

Because it is an area that affects daily life and interpersonal relationships,

it is also the reason why a line that approaches the sweating signal itself has taken root.

Gangnam underarm Botox is a hyperhidrosis care procedure that precisely injects botulinum toxin type A into the sympathetic nerve endings that control underarm sweat glands to block acetylcholine secretion for a certain period.

At the Gangnam branch, we operate 4 types of toxin lines from domestic, domestic premium, Xeomin, and Allergan with two options of 100 units and 200 units,

so it is a structure that can be selected according to your degree of hyperhidrosis, repeated procedure plan, and toxin preference.

The toxin and unit composition that suits your condition

will be checked directly during the consultation.
