Axillary hyperhidrosis
What Is Axillary Hyperhidrosis?
Our physician’s Real Cases: Axillary Hyperhidrosis
Before & after cases for this condition are currently being compiled and will be updated shortly. All cases represent actual clients of Luowei Medical Aesthetics Clinic with signed written Media Release Forms. The complete case portfolio is available for review during your consultation with our physician.
What Is Axillary Hyperhidrosis?
Axillary Hyperhidrosis Refers to localized axillary sweat production that exceeds Required for physiological thermoregulation, is Primary focal hyperhidrosis (PFH) The most common type. Affecting approximately 2–3% of the population, its impact is significant yet widely underestimated — most patients are unaware that this is a medical condition that can be treated or controlled.
5 Key Differences Between Primary and Secondary Hyperhidrosis
Age of onset — typically around puberty
Approximately 90% of primary hyperhidrosis cases develop before or during puberty, with patients often feeling “You sweat excessively”. Secondary hyperhidrosis typically appears suddenly in adulthood and warrants investigation for systemic disease.
Symmetric distribution — equal on both sides
Typical presentation of primary hyperhidrosis Bilateral symmetry (Both underarms, both hands, both feet, etc. Unilateral or generalized hyperhidrosis requires investigation for neurological, endocrine, or medication-related causes.
Stops at night — does not affect sleep
The hallmark features of primary hyperhidrosis are“Stops at night”— No sweating occurs during sleep. If night sweats are significant, secondary causes such as infection, malignancy, or hormonal imbalance should be investigated.
Positive family history — 30–50% have a familial predisposition
Approximately half of patients have a positive family history (a parent or sibling with the same condition), suggesting Autosomal dominant inheritance. However, the absence of a family history does not rule out primary hyperhidrosis.
Triggers — emotions, temperature, and food can all worsen the condition
Primary hyperhidrosis Stress, heat, caffeine, spicy food significantly worsens under these triggers, affecting both social interactions and work performance. Following Botox® treatment, the impact of these triggers is markedly reduced.
Severity Assessment (HDSS Scale)
- Grade 1: Sweating is barely noticeable and does not affect daily activities
- Grade 2: Sweating is noticeable and occasionally interferes with daily activities
- Grade 3: Sweating is almost constantly visible and frequently interferes with daily activities
- Grade 4: Sweating is severe and consistently interferes with daily activities
HDSS 3 Grade and above is considered Clinically significant hyperhidrosis, Botox Treatment has clear indications.
3 Major common lifestyle impacts
Clothing stains
White or light-colored shirts are perpetually stained under the arms, even with sweat pads. Many patients have worn only dark-colored clothing for years as a result.
Social anxiety
Afraid to raise your arms, afraid to hug, afraid to interview. Sweating → anxiety → more sweating: a vicious cycle.
Professional impact
Professions such as sales, consulting, public speaking, and performing are significantly affected. Important meetings, weddings, and major occasions frequently become sources of anxiety.
5 Step-by-step self-assessment
- Are you currently When not hot or stressed Still sweating continuously?
- Whether sweating Bilateral symmetry?
- Nighttime sleep Does it stop sweating entirely?
- Whether you are Around puberty does sweating begin?
- Whether it affects Clothing choices, social life, work?
3 or more items “yes”, You may be a strong candidate for Botox treatment of primary axillary hyperhidrosis. During your consultation, our physician will perform the Minor starch-iodine test for precise sweat zone mapping.
Causes and Mechanisms of Axillary Hyperhidrosis
The underlying mechanism of primary axillary hyperhidrosis is Excessive sympathetic cholinergic signaling Eccrine glands — not an abnormal number of sweat glands — are the source of the problem. Understanding this is key to understanding why Botox® is the most effective treatment.
Genetic factors
30–50% Patients frequently report a positive family history, suggesting an autosomal dominant inheritance pattern. The specific genes have not yet been fully identified, but the condition is associated with dysregulation of sympathetic nervous system activity.
Sympathetic overactivation
Under normal conditions, sweating is regulated by the hypothalamic thermoregulatory center via cholinergic sympathetic nerve fibers that control the sweat glands. In patients with primary hyperhidrosis,This regulatory system overreacts to stimuli.
Emotional triggers (sympathetic activation)
Stress, anxiety, and social situations activate the sympathetic nervous system → increased sweating → heightened anxiety → a vicious cycle. This is why many patients “The more anxious, the more you sweat”.
Temperature and food triggers
Hot environments, hot beverages, spicy food, caffeine, and alcohol can all worsen sweating. These are everyday triggers that are difficult to avoid entirely.
Secondary causes (conditions to rule out)
If sweating is Sudden onset, unilateral, generalized, prominent at night, accompanied by weight loss, Underlying causes to rule out include: hyperthyroidism, diabetes, lymphoma, infection, pheochromocytoma, medications (antidepressants, hormones), and menopause, among others.
Primary hyperhidrosis vs. secondary / anxiety-related / bromhidrosis
Not all “Excessive sweating” Not everyone is an immediate candidate for Botox® — it is essential to confirm whether the condition is primary and whether any co-existing issues are present before proceeding.
Vs Secondary hyperhidrosis
| Onset | Sudden onset in adulthood |
| Distribution | Generalized or unilateral |
| nighttime | Often prominent (night sweats) |
| Assessment | Rule out systemic disease first |
| Treatment | Primary disease treatment is the priority |
Vs Anxiety-induced sweating

Treatment considerations for axillary hyperhidrosis in Asian patients
Treatment of axillary hyperhidrosis in Asian patients differs slightly from Western populations in terms of dosage, social context, and co-existing concerns — however, the overall treatment protocol remains consistent.
1. A combination of axillary bromhidrosis and hyperhidrosis is common
Asian patients, particularly those of Chinese heritage, tend to have less active apocrine glands compared to European, North American, or Middle Eastern populations; however, a significant proportion of patients at the same time Excessive underarm sweating (eccrine gland overactivity) and underarm odor (apocrine glands) are distinct concerns. Botox® primarily treats hyperhidrosis; its effect on odor is limited.
2. High professional appearance demands
In Asian urban professional environments — particularly finance, consulting, sales, and healthcare —Frequently wearing formal attire, Stained white shirts and ruined silk blouses are all too familiar. Excessive underarm sweating can significantly impact your professional image — making effective treatment a pressing priority.
3. Weddings / important occasions
Asian weddings typically White wedding dress + extended toasting, Any underarm dampness is “Wedding nightmare”. Our physician has extensive clinical experience with preventive treatments scheduled 6 weeks before weddings.
4. Personalized dosage
Asian patients tend to have a smaller overall body frame, but dosing for axillary hyperhidrosis is primarily determined by Underarm zone Dosage is determined by clinical assessment, not body weight. Our physician uses Minor’s test to precisely map the treatment area and tailor the dose, typically 50–100 units per side.
Dosage reference × severity
| HDSS | Sweating area | Dosage per side |
|---|---|---|
| Grade 2 | < 5×5cm | 30–40 units |
| Grade 3 | 5–8cm | 40–50 units |
| Grade 3–4 | 8–12cm | 50–75 units |
| Grade 4 | > 12cm | 75–100 units |
Maintenance frequency reference
- Most patients return every 5–7 months
- Severe cases may last 4–5 months
- Mild cases and cooler seasons may extend results to 9 months
- For best results, treat 4–6 weeks before summer
Axillary Hyperhidrosis Treatment Options (Botox® is the Gold Standard)
FDA Botox® (onabotulinumtoxinA) has been approved for axillary hyperhidrosis for over 20 years, with a clinical efficacy rate exceeding 90%, making it Most effective, safest, and longest-lasting non-surgical treatment.
Botox® Underarm injection Gold standard
NMPA-registered for axillary hyperhidrosis since 2004, with a clinical efficacy rate of 90%+. Our physician’s expertise in Botox® injections for axillary hyperhidrosis Precise grid mapping + personalized dosage is one of our physician's signature procedures.
- 50–100 units per side (based on treatment area)
- 1–1.5cm Grid pattern · 25–50 multi-point injections
- 4–7 Days to onset · full effect at 2 weeks
- Results last 5–9 months
- Minimal downtime · Return to work the same day
Minor Starch-iodine test Essential for diagnosis
The gold standard for diagnosis and mapping: iodine solution is applied to the underarm, allowed to dry, then starch is dusted over — active sweat zones turn dark purple-black, precisely identifying the treatment area and guiding Botox injection point design.30 Minutes to complete · safe and comfortable.
Topical anesthesia + ice application Comfort optimization
Topical lidocaine applied 20 minutes before injection, combined with ice packing, significantly reduces discomfort during multi-point injections. Both are standard components of our physician’s protocol to ensure a comfortable treatment experience.
Prescription antiperspirant First-line option for mild cases
Prescription antiperspirants containing aluminum chloride (20% or higher), such as Drysol, are mild A first-line treatment for hyperhidrosis that can be combined with Botox® to help maintain results. Note: nighttime skin irritation may occur.
Oral anticholinergic medications Alternative options
Oral medications such as oxybutynin may provide short-term relief, but Noticeable side effects (dry mouth, constipation, and drowsiness — making it unsuitable for long-term use. Botox® is a more reliable option.
MiraDry® / Microwave ablation Permanent option
NMPA-registered microwave technology,Permanent destruction of sweat glands. Advantages: permanent results. Disadvantages: lower efficacy than Botox® (75% vs. 90%+), prolonged post-procedure swelling, higher cost, and suboptimal outcomes in some patients.We do not offer miraDry in-clinic, but clients are welcome to ask us to help compare options.
Endoscopic thoracic sympathectomy (ETS) Extreme option
Surgical procedure: thoracoscopic resection of the sympathetic nerve chain.Not recommended for axillary sweating alone— High risk, with compensatory sweating occurring in 60%+ of cases (increased sweating elsewhere on the body). Reserved only for severe cases where all other options have failed.
Treatment Decision Chart
| Severity | Recommended treatment plan |
|---|---|
| HDSS 1–2 mild | Prescription antiperspirant → if no relief, proceed to Botox |
| HDSS 3 Moderate | Botox First-line choice |
| HDSS 4 Severe | High-dose Botox® + long-term maintenance |
| Botox Repeatedly effective but seeking a permanent solution | Discuss miraDry options |
| All treatment options have failed | Surgical referral (rare) |

Axillary hyperhidrosis Botox® is “Medical” rather than “cosmetic”
NMPA-registered since 2004, Botox® is the gold-standard treatment for axillary hyperhidrosis. Our physician delivers this treatment with physician-level precision and accountability.Significantly improves quality of life treatment.
About the Cost of Botox® Treatment for Axillary Hyperhidrosis
Many patients ask during their first consultation: “How many units are needed and what is the cost?” However, this type of “Priced per unit” The way questions are framed can lead you to decisions that are not in your best interest. When it comes to Botox® for axillary hyperhidrosis,90% of treatment effectiveness depends on whether the dosage is sufficient to fully cover your sweating zone— If the goal is “Save units” Under-dosing leads to suboptimal results — and that is simply a waste. That is why we always perform a Minor starch-iodine test first, mapping your actual sweat distribution to determine the right individualized dose for you.
At Luowei Medical Aesthetics Clinic, axillary hyperhidrosis with Botox® Performed personally by the physician— Because treatment involves a multi-point grid design, individualized dosage decisions, and clinical judgment around touch-up injections — all of which directly affect outcomes and longevity — physician oversight is essential. Our physician uses axillary hyperhidrosis injections as a standard case in the physician training programme. Routine maintenance visits for established long-term patients with a stable protocol may be performed by trained clinical staff under physician supervision, and are priced accordingly.
We do not publish a standard price list online, because doing so shifts focus to numbers rather than the factors that truly determine outcomes — your sweat zone, HDSS severity, target dryness level, and desired maintenance frequency all shape the right plan and its cost. After a Free 30-Minute Consultation, our physician will clearly outline your sweat zone, recommended dosage, and corresponding fee structure so you can make a fully informed decision.Treatment decisions should be driven by clinical need, not price.
- Payment is made at the clinic, after the consultation and before treatment begins
- Nothing is paid in advance, and no deposit is required to hold an appointment
- Cosmetic treatment is a self-pay item and is not covered by public medical insurance in China
- All new clients receive a complimentary 30-minute Free Consultation assessment
