Sweating Botox

What is Sweating Botox?

Sweating Botox — also known as hyperhidrosis treatment, anti-sweat injections, or underarm Botox — is a non-surgical solution for people who sweat excessively regardless of temperature, stress, or activity. By injecting small amounts of botulinum toxin just below the skin, your doctor can block the nerve signals that activate the sweat glands, dramatically reducing sweat production in the treated area for 6 to 9 months per session.

It’s one of the most life-changing treatments we offer. Patients with axillary hyperhidrosis (excessive underarm sweating) often describe it as transformative — no more ruined shirts, no more deodorant layering, no more social anxiety about raised arms. The same technique works for palmar (hands), plantar (feet), and craniofacial (scalp and forehead) hyperhidrosis.

At Dr. Cigdem Ozden Clinic, we use exclusively FDA-approved Botox (Allergan) and Dysport for all hyperhidrosis treatments. Botox is FDA-approved specifically for severe primary axillary hyperhidrosis, backed by decades of safety and efficacy data.

How Hyperhidrosis Botox Works

Sweat glands are controlled by a branch of the nervous system called the sympathetic nervous system. In patients with hyperhidrosis, this system overreacts, triggering the sweat glands to release sweat even in the absence of normal triggers like heat or exercise.

Botulinum toxin works by temporarily blocking the release of acetylcholine — the chemical messenger that tells the sweat glands to activate. When the signal is interrupted, the glands simply stop producing sweat in the treated area. Other areas of the body continue to sweat normally, so your overall ability to thermoregulate is unaffected.

Step-by-Step: What Happens After Injection

1. Injection: Botox is placed just under the skin across a grid pattern in the affected area
2. Binding: The toxin binds to nerve endings that control the sweat glands
3. Blocking: Acetylcholine release is inhibited, preventing sweat gland activation
4. Drying: Sweat production in the treated area drops by 80-95% within 3-7 days
5. Long-lasting relief: Full effect is reached at 2 weeks and lasts 6-9 months
6. Gradual return: Sweating slowly resumes as new nerve endings form and Botox wears off

Am I a Good Candidate?

Sweating Botox is suitable for most adults with primary hyperhidrosis — excessive sweating without an underlying medical cause. You may be an ideal candidate if:

• You sweat excessively from your underarms, hands, feet, or scalp regardless of temperature or activity
• Antiperspirants (including clinical-strength and prescription aluminium chloride) have not worked
• You have stopped wearing certain colours or fabrics because of visible sweat marks
• Sweating affects your confidence, relationships, or work
• You’ve been diagnosed with primary focal hyperhidrosis or recognise the symptoms
• You are not pregnant or breastfeeding
• You do not have a neuromuscular condition such as myasthenia gravis

Axillary, Palmar, Plantar, and Craniofacial Hyperhidrosis

Botox works for all four major types of focal hyperhidrosis, though the experience varies:

Axillary (underarm) hyperhidrosis is the most common area we treat and delivers the most reliable, comfortable results. The skin is thin, the injections are quick, and patients are typically back to normal within minutes. Most patients treat both underarms in a single session.

Palmar (hand) hyperhidrosis responds very well to Botox, but the injections are more sensitive due to the high nerve density in the palms. We typically use a topical numbing cream or ice packs. Hand treatment is highly effective for patients whose sweaty palms affect work, handwriting, or social interaction.

Plantar (feet) hyperhidrosis is similar to palms — effective but mildly uncomfortable. Excellent for patients who struggle with slippery shoes, foot odour, or athletes’ foot.

Craniofacial hyperhidrosis (excessive scalp and forehead sweating) is treated with a scattered grid of small injections and is particularly appreciated by patients who sweat through their hair during meetings, workouts, or travel.

Sweating Botox for Men

Male patients make up a significant portion of our hyperhidrosis cases — the condition is equally common in men and women, but men often report higher daily impact (visible sweat through shirts, suit jackets, business environments). Men may require slightly higher doses in the underarms due to larger surface area.

The Treatment Process

A typical underarm hyperhidrosis session takes 20-30 minutes from start to finish. Here’s exactly what to expect at our Istanbul clinic:

Consultation

Your doctor will ask about your symptoms, when sweating started, which areas are affected, and what treatments you’ve already tried. For underarm cases, a Minor’s starch-iodine test can be used to precisely map the areas of most active sweating, though this is optional. Your medical history is reviewed to confirm that Botox is appropriate for you.

Preparation

The treatment area is cleaned with an antiseptic wipe. For underarm treatment, no numbing is typically required — the injections are quick and superficial. For hands, feet, or scalp, topical numbing cream or ice is applied beforehand for comfort. Your doctor will mark the injection grid across the treatment area.

Injection

Using ultra-fine 32-gauge needles, your doctor administers small amounts of Botox just under the skin across a grid pattern — typically 15-20 points per underarm. Each injection takes a second, and the entire grid is completed within a few minutes per side.

Aftercare

You can return to all normal activities immediately. There are no visible signs of treatment, no bandaging, and no restrictions on movement. You’ll receive written post-treatment instructions before you leave.

Benefits of Hyperhidrosis Botox

• Reduces sweating by 80-95% in the treated area
• Long-lasting relief: 6-9 months per treatment, significantly longer than facial Botox
• FDA-approved for severe primary axillary hyperhidrosis
• Zero downtime: return to work, gym, and social life immediately
• No surgery, no scarring, no implants
• Works for underarms, hands, feet, and scalp
• Restores confidence in clothing choices, social settings, and professional environments
• Reduces body odour indirectly by reducing the sweat that bacteria feed on
• Significant cost savings in Istanbul compared to US, UK, and Western Europe
• Reversible: effects wear off naturally, no long-term changes to your body

Risks and Side Effects

Sweating Botox is a well-established, low-risk procedure when performed by an experienced doctor. Because it uses superficial injections rather than deep muscle injections, the risk profile is even lower than many cosmetic applications of Botox.

Common (Mild, Temporary)

• Small red bumps or pinpoint bleeding at injection sites: resolve within 30-60 minutes
• Mild bruising at injection points: rare in the underarms, slightly more common in the palms
• Mild tenderness or soreness in the first day: uncommon and resolves quickly
• Temporary increased sweating in other areas (compensatory): very mild in hyperhidrosis cases and typically unnoticed

Less Common

• Hand weakness after palmar injections: a rare, temporary reduction in grip strength (typically mild and resolves within 2-4 weeks). This is why palmar Botox should only be performed by experienced injectors who understand the anatomy of the hand.
• Asymmetric response: one side may respond faster than the other. Corrected at your free touch-up.
• Incomplete response: some patients find small “hot spots” of residual sweating after 2 weeks. These can be touched up at no charge.

Rare

Serious systemic side effects from hyperhidrosis Botox are extremely rare at the doses used. Botox has an excellent safety record for this indication, and it is one of the most common off-label uses of botulinum toxin worldwide.

Before & After Care

Before Your Treatment

• Avoid blood thinners (aspirin, ibuprofen, naproxen) for 3 days prior if safe to do so
• Avoid alcohol for 24 hours before your appointment
• Shave the underarms 24 hours before treatment (not on the day of, to avoid irritation)
• Do not apply deodorant, antiperspirant, or lotion to the underarms on the day of treatment
• Inform your doctor of all medications and supplements you take
• Wear loose-fitting, dark clothing to your appointment for comfort

After Your Treatment

• Do not massage or press on the injection sites for 24 hours
• Avoid intense exercise, saunas, and hot tubs for 24 hours
• You can shower normally and resume deodorant the day after treatment
• Sweating begins to reduce within 3-7 days
• Full dryness is reached at 2 weeks
• Effects last 6-9 months on average, with some patients reporting up to 12 months

Your free touch-up is available 2-3 weeks after initial treatment. If any residual sweating hot spots remain, we’ll address them at no additional cost.

Hyperhidrosis Botox Cost in Istanbul

Hyperhidrosis treatment requires significantly more Botox than facial treatments (typically 50-100 units total, compared to 10-30 for the forehead), which is why it costs more. However, it also lasts 2-3 times longer than facial Botox — most patients treat once or twice a year instead of every 3-4 months. Dr. Cigdem Ozden Clinic uses the same FDA-approved products and physician standard as clinics in the US and UK, at a fraction of the price.

Why Istanbul?

Istanbul has become one of the world’s top destinations for medical and aesthetic treatments, and hyperhidrosis Botox is one of the most requested functional treatments among international patients. The combination of board-certified doctors, FDA-approved products, and significant cost savings makes it especially attractive for patients travelling from the UK, Europe, the US, and the Gulf — particularly for a treatment that isn’t always covered by insurance in their home country.

At Dr. Cigdem Ozden Clinic specifically:

• Same products: Genuine Allergan Botox and Dysport, sourced from authorised distributors with batch verification available on request
• Board-certified doctors only: Every treatment is performed by an experienced physician, not a nurse, aesthetician, or technician
• Transparent pricing: $500 for bilateral underarm treatment, identical for local and international patients, no hidden fees
• Free touch-up included: If residual sweating remains after 2 weeks, we adjust at no charge
• Combine with travel: Your clinic visit takes 30 minutes and leaves the rest of the day free to enjoy Istanbul

Frequently Asked Questions

How many units of Botox are needed for hyperhidrosis?

Most patients require 50-100 units total for bilateral underarm treatment (typically 50 units per underarm). Palms, feet, and scalp may require similar or slightly different amounts depending on the surface area. Dosing is standardised based on FDA guidelines for severe primary axillary hyperhidrosis, and your doctor will adjust based on your anatomy and severity during consultation.

How much does sweating Botox cost in Istanbul?

At Dr. Cigdem Ozden Clinic, the price is $500 for bilateral underarm treatment (both armpits). This includes your consultation, the treatment itself, and a free touch-up 2-3 weeks later. The same treatment typically costs $1,000-$1,800 in the US and $900-$1,500 in the UK, where it is often not covered by insurance for cosmetic hyperhidrosis.

Does sweating Botox hurt?

Underarm injections are generally rated 1-2 out of 10 for discomfort — the skin is thin and the needles are very fine. Palmar (hand) and plantar (foot) injections are more sensitive due to the higher nerve density in these areas, so we apply topical numbing cream or ice beforehand. Most patients tolerate all treatments comfortably.

How long does hyperhidrosis Botox last?

Effects typically last 6-9 months for underarm hyperhidrosis, which is significantly longer than facial Botox. Some patients report up to 12 months of dryness. Hand and foot treatments tend to last slightly less — around 4-6 months — because of the higher nerve regeneration rate in those areas. Most patients schedule treatments once or twice a year.

Will I stop sweating completely?

In the treated area, sweat production is reduced by 80-95% — effectively eliminating excessive sweating without stopping it entirely. This is intentional: a small amount of normal sweat production is healthy and helps the skin regulate temperature. The rest of your body continues to sweat normally, so thermoregulation is unaffected.

Is hyperhidrosis Botox safe?

Yes. Botox is FDA-approved specifically for severe primary axillary hyperhidrosis and has an excellent safety track record with decades of clinical use. Because the injections are superficial (just under the skin) rather than deep (into muscle), the systemic risk profile is even lower than many cosmetic applications. Side effects are typically limited to mild injection-site reactions that resolve within an hour.

Can Botox treat sweaty hands or feet?

Yes — palmar (hand) and plantar (foot) hyperhidrosis both respond well to Botox. Results are typically excellent, though the injections are more sensitive than underarm treatment due to higher nerve density. We apply topical numbing cream or use ice to keep the experience comfortable. Results in the hands and feet typically last 4-6 months.

Can Botox help with scalp and facial sweating?

Yes. Craniofacial hyperhidrosis — excessive scalp and forehead sweating — responds very well to Botox. A scattered grid of small injections across the scalp and forehead dramatically reduces sweating during workouts, meetings, or hot weather, while having no effect on facial expressions when placed correctly.

Will Botox stop body odour?

Indirectly, yes. Body odour is caused by bacteria on the skin breaking down sweat. By dramatically reducing sweat in the treated area, Botox removes the primary food source for those bacteria, which typically results in a significant reduction in odour as well. Many patients who also struggle with bromhidrosis (excessive body odour) report improvement after their treatment.

How soon will I see results?

Sweat reduction typically begins within 3-7 days, with the full effect reached at 2 weeks. If you still notice residual hot spots after 2 weeks, your free touch-up can address them precisely.

Can I use deodorant after the treatment?

Yes. You can resume your normal deodorant or antiperspirant routine the day after treatment. Most patients find they no longer need antiperspirant once the Botox takes effect, though some prefer to continue using deodorant for scent alone.

Will I sweat more in other areas to compensate?

Compensatory sweating is a well-known concern after surgical hyperhidrosis treatments like ETS (endoscopic thoracic sympathectomy), but it is very uncommon with Botox. Because Botox only affects the small treated area temporarily, the body does not trigger significant compensatory sweating elsewhere. The few patients who notice mild compensation usually find it minor and acceptable compared to the relief in the treated area.

Is hyperhidrosis Botox permanent?

No. The effects wear off gradually over 6-9 months as new nerve endings form and the sweat glands regain their connection to the nervous system. Treatment can be repeated indefinitely without loss of effectiveness. Unlike surgical options, there are no permanent changes to your body.

Can I combine sweating Botox with other treatments?

Yes. Hyperhidrosis Botox can be combined with facial Botox, dermal fillers, skin treatments, or other aesthetic procedures in the same visit. Your doctor will advise on the best combination and any adjustments needed to ensure comfort and safety during the session.

What’s the difference between Botox and antiperspirant for hyperhidrosis?

Clinical-strength and prescription antiperspirants (such as aluminium chloride) work by temporarily plugging the sweat ducts and must be reapplied frequently — often causing skin irritation. Botox works at the nerve level, preventing the glands from being activated in the first place. One treatment provides 6-9 months of dryness without daily reapplication or skin irritation. For patients whose hyperhidrosis does not respond to antiperspirants, Botox is typically the next step before considering surgical options.
