Axillary Hyperhidrosis Treatment in Bucharest: Botulinum Toxin Injection for Underarm Sweating
Up to 90% reduction in underarm sweating, through a minimally invasive 15-20 minute procedure performed by dermatologists. Effect that usually lasts between 6 and 9 months.
What is axillary hyperhidrosis and how does it manifest itself?
Axillary hyperhidrosis is a chronic medical condition characterized by excessive, constant, and uncontrolled sweat production in the armpits. This underarm sweating occurs independently of physical exertion or ambient temperature, exceeding the limits of normal thermoregulation.
It is triggered by the overactivity of the eccrine sweat glands in this area. Unlike normal physiological sweating, which occurs in times of thermal overload or physical exertion, in the case of hyperhidrosis the glands secrete fluid constantly, often independently of the patient's emotional state. It is the most common form of focal hyperhidrosis and is recognized by the following manifestations:
- Constant wetting of clothes in the axillary region, often just a few dozen minutes after cleaning and dressing.
- The appearance of unsightly stains on clothing, which can degrade fabrics at an accelerated rate.
- The risk of unpleasant odor (bromhidrosis), caused by the bacterial decomposition of sweat on the surface of moist skin.
The impact of excessive underarm sweating on quality of life
Excessive underarm sweating severely affects the quality of life of patients, generating profound social anxiety, isolation and major clothing limitations. The constant fear of visible stains on clothes and unpleasant odor drastically limits professional performance and confidence in daily interactions.
This social anxiety often leads to restrictive coping behavior: patients choose their clothing exclusively based on colors that can mask humidity (usually black or white), avoid large gestures or raising their arms, and may experience a significant decrease in productivity at work. At our clinic in Bucharest, we approach this problem with maximum empathy and professionalism, offering a medical solution aimed at restoring daily comfort.
Self-assessment: How severe is your underarm sweating? (HDSS scale)
In international dermatological practice, determining the treatment indication is not only based on a visual assessment, but also by using scientifically validated tools. The most widely used algorithm is the HDSS (Hyperhidrosis Disease Severity Scale), a self-assessment score focused on how excessive sweating affects your daily activities. Analyze the 4 statements below to identify which stage you fall into:
| HDSS score | Description of clinical manifestations | Severity | Medical indication |
|---|---|---|---|
| Score 1 | Underarm sweating is never noticeable and does not affect my daily activities in any way. | Light / Normal | It does not require dermato-aesthetic medical treatment. |
| Score 2 | Underarm sweating is tolerable, but sometimes it disrupts or limits my daily activities. | Mild to Moderate | May benefit from dermatological counseling or optimization of standard topical therapies. |
| Score 3 | My underarm sweating is difficult to tolerate and frequently disrupts my daily activities (choosing clothes, professional interactions). | Severe | Clear indication for botulinum toxin injection therapy. |
| Score 4 | Underarm sweating is completely intolerable and constantly and severely disrupts all my daily activities. | Severe | Priority indication for intervention with botulinum toxin (form refractory to usual solutions). |
Medical note: Patients who are in the Score 3 and Score 4 categories show the highest degree of clinical satisfaction following the injectable treatment in our clinic in Bucharest, achieving rapid improvement in the described discomfort.
Treatment protocol: timeline of your results
To eliminate any uncertainty, we have structured the complete course of the procedure into a clear timeline, based on the patient's standard physiological evolution after botulinum toxin administration:
Day 0: Clinic visit and procedure
A dermatological consultation takes place, topical anesthetic cream is applied, and sterile microinjections are performed (15-20 minutes). Discomfort is minimal.
You can leave the clinic immediately. There may be small red dots or a slight swelling at the injection sites, which usually disappear within a few hours. It is recommended to avoid deodorants on this day.
Days 1-2: Period of minimal restrictions
The substance begins to bind to receptors in the sweat glands. Sweating is still present, but may slightly reduce its intensity.
Avoid intense physical exertion, gym workouts, saunas, hot baths, or local massage in the armpits to prevent unintentional diffusion of the substance.
Days 3-5: First visible effects
Most patients begin to notice a significant decrease in underarm moisture. Clothes stay dry throughout the day, and the need for harsh antiperspirants is significantly reduced.
Day 14: Installing the full effect
The botulinum toxin completely blocked the release of acetylcholine in the treated area. The maximum therapeutic effect is achieved, with a reduction in sweat secretion of up to 80-90%. If necessary, the dermatologist can evaluate the result during a routine check-up.
Months 6-9: Stabilized comfort
You enjoy a prolonged period of comfort, without stains on your clothes and without social anxiety. Gradually, towards the end of this interval, the activity of the glands slowly and naturally resumes, signaling the right time for another maintenance session.
How does botulinum toxin help in the treatment of underarm sweating?
Botulinum toxin type A is internationally recognized as the gold standard in the non-surgical management of moderate-to-severe axillary hyperhidrosis. The mechanism of action is simple and effective: the intradermally injected substance acts as a localized neurological blocker, temporarily interrupting the transmission of the chemical signal (acetylcholine) from nerve endings to the sweat glands in the armpit.
No longer receiving the "order" to secrete fluid, the glands drastically reduce their activity, by up to 90%, without affecting the body's natural thermoregulation process. The treatment acts strictly on the superficial layer of the skin and does not affect the deep anatomical structures or lymph nodes in the axillary region.
Steps of the axillary injection procedure at Skina Clinic
To ensure optimal results and a maximum level of safety, we follow a rigorous medical protocol, structured in three stages:
- Medical consultation and evaluation: The dermatologist analyzes your medical history and delimits the hyperactive area of the armpit.
- Area preparation and anesthesia: The armpits are disinfected according to sterile clinical standards. For your complete comfort, we apply a topical anesthetic cream approximately 30-45 minutes before the procedure or use controlled local cooling techniques.
- The actual procedure: Using a microscopic, extremely fine needle, the doctor injects very small amounts of botulinum toxin evenly distributed in a network, at distances of approximately 1-1.5 cm across the entire surface of the affected armpit. The entire process takes 15-20 minutes.
Results, duration and post-treatment recommendations
The effects are not instant, but they set in relatively quickly. Most patients notice a significant reduction in moisture after the first 2-4 days after the injection, with the final result being assessed 10-14 days post-procedure.
How long does the effect last? The duration of clinical benefits usually varies between 6 and 9 months, being influenced by each body's metabolic rate, lifestyle and initial severity of the condition. As neurotransmitters gradually resume their activity, sweating returns to its previous level, which is why it is recommended to repeat the procedure once or twice a year.
Recommendations after the clinic visit
- Avoid applying classic deodorants or antiperspirants to the treated area for the first 24 hours.
- Avoid intense physical exertion, the gym and exposure to high temperatures (sauna, solarium, hot baths) for 48-72 hours.
- Do not massage or press on the armpit area in the first few days after the injection.
Preparing for the axillary hyperhidrosis treatment procedure
Proper preparation optimizes the effectiveness of the injectable procedure and prevents local skin irritation. For the clinic visit, it is recommended to epilate or shave the armpits 24-48 hours before and avoid applying any antiperspirant the morning of the procedure. Also, wear loose clothing and avoid non-steroidal anti-inflammatory drugs to reduce the risk of minor bruising.
What are the factors that determine the cost of treatment?
The cost of treatment for axillary hyperhidrosis is determined by the quality of the substance used and the number of botulinum toxin units injected. Our clinic uses premium protocols with full doses of 100 units (e.g. Vistabel from Allergan/AbbVie), guaranteeing the safety and durability of the clinical result.
Frequently asked questions about the treatment of excessive underarm sweating
Is it safe to block sweat in the armpits? Where does the sweat go?
Yes, the procedure is completely safe. The armpit area represents only about 11% of the total sweat glands in the human body. Localized blockage of these glands does not affect the overall thermoregulation capacity; excess heat is eliminated normally through the rest of the skin surface, without the patient feeling a visible increase in sweating in other areas (a rare phenomenon in the case of injection, unlike surgery).
How many units of botulinum toxin are needed for the armpits?
The dosage is determined by the dermatologist based on clinical assessment and the size of the affected area. In general, the standard protocol uses approximately 50 units for each armpit (a total of 100 units for both arms), for effective and uniform blocking.
Are there any contraindications for axillary Botox treatment?
The procedure cannot be performed in case of pregnancy or breastfeeding, in the presence of peripheral neurological conditions (such as myasthenia gravis), or if there is an active infection or irritation of the skin of the armpit (for example, hidradenitis or severe eczema). All these aspects are rigorously checked by our doctor during the initial consultation.
