Hyperhidrosis Treatment in Toronto & Markham
— Injectable Treatment · Recovery period 24–48 hours · Suitable for all skin types, Fitzpatrick I–VI
Quick Answer
Hyperhidrosis injections use Botox® and comparable neuromodulators to treat excessive sweating (hyperhidrosis) by temporarily blocking the nerve signals that trigger sweat glands. These Health Canada–licensed injectables are suited for adults whose underarm, palmar, or plantar sweating has not responded adequately to topical treatments. At ID Cosmetic Clinic in Markham and Toronto, this treatment is personally performed by physician Dr. Dan Xu, M.D., CCFP. Most patients see a meaningful reduction in sweating within one to two weeks, with results typically lasting four to twelve months per session.

Hyperhidrosis treatment at our Toronto and Markham clinic
Botulinum toxin injections temporarily block acetylcholine — the signal your nerves use to switch on a sweat gland. Injected in a shallow grid across the affected skin, they reduce sweating in that area for several months without affecting how the rest of your body regulates temperature.
In Canada, botulinum toxin type A is authorized for severe primary axillary hyperhidrosis — underarm sweating that persists despite prescription antiperspirant. Palms, soles and forehead are treated at physician discretion where the clinical picture supports it; those uses are not covered by the Canadian product monograph, and we say so before you book.
Every injection at ID Cosmetic Clinic is performed by Dr. Dan Xu personally. Sweat-gland injections are shallow and numerous — depth and spacing decide both how well it works and how long it lasts.
Key points
- What is injectedBotulinum toxin type A, diluted for intradermal delivery
- Where it actsEccrine sweat glands in the treated area only
- Appointment length30–45 minutes for underarms, including mapping
- Onset4–7 days, with the full effect by about 2 weeks
- DurationCommonly 6–9 months for underarms; shorter for palms
- DowntimeNone — small bumps at the injection sites settle within hours
Where this page fits
This page covers the treatment — areas, dosing, what the appointment involves, and cost. If you are still working out whether what you have is hyperhidrosis, what causes it, or how it is graded and diagnosed, start with our page on axillary hyperhidrosis instead.
Does it stop you sweating everywhere?
No. Only the injected area is affected. Your body has several million sweat glands; treating both underarms addresses a very small fraction of them, and thermoregulation elsewhere is unchanged. Compensatory sweating — a recognised issue after surgical sympathectomy — is not an expected outcome of localised injections.
How sweat-gland injections work
Sweating is triggered when a nerve ending releases acetylcholine onto an eccrine sweat gland. Botulinum toxin prevents that release, so the gland receives no instruction to produce sweat. The gland itself is not damaged — once the effect wears off, normal function returns.
Why injection depth matters
Eccrine glands sit in the deep dermis, much shallower than the muscles targeted in cosmetic injections. Placed too deep, the product reaches muscle instead of gland — which is how palm treatments end up causing temporary grip weakness. Placed too shallow, it leaks and the effect is patchy.
This is also why the number of injection points is high: each point covers a small radius of diffusion, so an underarm typically needs 15–20 evenly spaced points per side rather than a few large deposits.
Mapping before injecting
Where you sweat most is not always where you think. Before treating underarms, we can use a starch-iodine test — iodine solution and starch powder turn dark where sweat is actively produced — to outline the area that actually needs covering.
Mapping matters because dose follows area. Treating a mapped zone uses product where it works instead of spreading a fixed dose over a guessed rectangle.
Underarms, palms, soles and forehead — what differs
These are not one treatment applied in four places. Dose, comfort, duration and regulatory status all differ by area, and so does whether we will recommend it at all.
| Area | What to expect | Typical duration | Status in Canada |
|---|---|---|---|
| Underarms | The most straightforward area. Well tolerated with topical numbing; mapping optional but useful. | 6–9 months | Authorized for severe primary axillary hyperhidrosis |
| Palms | The most uncomfortable area to treat — palm skin is densely innervated, and nerve blocks or strong topical anesthesia are usually needed. Temporary weakness of fine grip is a recognised effect. | 3–4 months | Off-label |
| Soles | Similar comfort considerations to palms. Thicker skin makes even placement harder and results more variable. | 3–4 months | Off-label |
| Forehead / scalp | Requires care near the frontalis — product reaching the muscle can drop the brow. Lower doses, wider spacing. | 3–5 months | Off-label |
Durations are what we commonly observe; individual response varies with dose, area and sweat severity. Off-label means the use is not listed in the Canadian product monograph — it is a clinical decision made with you, not an authorized indication.
Am I a Candidate for Botox® Hyperhidrosis Treatment?
- You may be a good candidate if you experience any of the following:
- Excessive sweating of the underarms, palms, soles, or back
- Antiperspirants or medications have not provided adequate relief
- Seeking a quick, non-invasive way to stay dry
- Feeling self-conscious or bothered by excessive sweating
- Seeking a solution with minimal side effects and long-lasting results
- You may not be a suitable candidate if you have:
- Pregnancy or breastfeeding
- Presence of a neuromuscular disorder (e.g., myasthenia gravis)
- Allergy to botulinum toxin components
- Active skin infection or open wound in the treatment area
What the appointment involves
A first underarm treatment takes about 30–45 minutes from arrival to leaving, most of which is assessment and numbing rather than injecting.
| Stage | What happens |
|---|---|
| Consultation | History, severity, what you have already tried, and whether anything suggests a secondary cause. If prescription antiperspirant has not been given a fair trial, we will say so. |
| Mapping | Starch-iodine test where useful, to outline the actively sweating zone and set the dose to the area. |
| Preparation | Cleansing, topical anesthetic for 15–20 minutes. For palms, a stronger approach is discussed in advance. |
| Injection | A shallow grid of small injections, typically 15–20 points per underarm. Most people describe brief stinging rather than pain. |
| Afterwards | Cool compress. You can drive and return to work the same day. |
| Review | A check at 2–3 weeks, when the full effect is present, to confirm coverage and top up any missed area. |
Results timeline
| When | What you should notice |
|---|---|
| Days 4–7 | Sweating starts to reduce |
| Week 2 | Full effect; this is the level to judge the treatment by |
| Months 6–9 | Effect fades gradually rather than stopping abruptly |
| Repeat | When sweating returns to a level that bothers you — many patients treat once before summer |
What sweat injections can and cannot address
Botulinum toxin treats excessive sweating itself. It does not treat every complaint that involves sweat.
| Concern | Does this treatment help? | Notes |
|---|---|---|
| Primary axillary hyperhidrosis | Yes — the authorized indication | Best evidence and the most predictable result |
| Sweating that soaks through clothing daily | Yes | The practical threshold most patients describe |
| Palmar or plantar sweating affecting work | Often — off-label | Shorter duration, more uncomfortable to treat |
| Body odour with normal sweat volume | Partly | Reducing sweat reduces the moisture bacteria act on, but odour has other causes; assess separately |
| Sweating that started recently, at night, or with weight loss | No — see a physician first | These suggest secondary hyperhidrosis with an underlying cause that needs investigating, not masking |
| Sweating only in specific social situations | Sometimes | Treating the sweat can break the anxiety loop, but it does not treat the anxiety |
