Botox for Hyperhidrosis: Sweat Reduction Treatment

SKIN VITALITY PROUDLY SERVING CANADIANS SINCE 1992

Botox® injections for excessive sweating (hyperhidrosis) block the chemical signal that activates sweat glands, providing long-lasting relief from underarm sweating, sweaty palms, sweaty feet, and facial sweating.

Sweat Reduction With Botox® for Hyperhidrosis

For individuals who experience excessive sweating that is not related to heat or physical activity, Botox hyperhidrosis treatment offers a non-surgical option to help reduce sweat production in targeted areas. Hyperhidrosis is a medical condition where sweat glands activate more often than required for temperature regulation. Treatment plans vary based on the area involved, the extent of sweating, and individual physiology.

Understanding Hyperhidrosis

Individuals with hyperhidrosis may experience moisture unrelated to temperature, stress, or activity. Topical antiperspirants may not always provide sufficient support, which is why non-surgical sweat-reduction treatments such as Botox may be considered.

The excess sweat becomes present without engaging in tasks that require physical movement or muscular effort, and it doesn’t depend on the exposure to heat. Hyperhidrosis involves sweating that exceeds the body’s natural cooling needs. It can be localized or generalized and may affect:

  • Underarms (axillary hyperhidrosis)
  • Palms (palmar hyperhidrosis)
  • Soles
  • Face and scalp
  • Back, chest, and other regions

How Botox Helps Reduce Excessive Sweating

Botox temporarily affects the nerve signals that trigger sweat gland activity. When placed just beneath the skin’s surface, the product can help reduce sweat production within the treated area. Studies have shown that Botox can successfully treat sweaty palms in 80 – 90% of cases.

Botox is approved by Health Canada for axillary hyperhidrosis (underarms). Medical teams may also use it for other areas such as the palms, soles, and face under off-label use where clinically appropriate. Individual timelines vary based on anatomy, the area treated, and lifestyle factors.

This treatment can help with:

  • Reduced sweat production in targeted regions
  • More comfortable daily routines
  • Non-surgical sweat reduction
  • Support for both primary and secondary hyperhidrosis patterns
  • A treatment duration that may last several months depending on the area

Hyperhidrosis Treatment Areas

Hyperhidrosis can be classified as generalized or localized depending on the body part affected. It can also be classified by onset, either congenital (present at birth) or acquired (beginning later in life). Currently, the treatment of Hyperhidrosis through Botox injections has been approved by Health Canada and the FDA for the underarm area. Medical practitioners have also been using Botox “off-label” to treat other areas of the body susceptible to Hyperhidrosis. Many studies have outlined the effectiveness of this treatment to help those experiencing an excess of sweat.

Primary

Primary Hyperhidrosis is categorized by the areas that have the highest number of sweat glands. These areas include the hands, feet, armpits, groin and face. When the excess sweat is in a localized area i.e. palms, soles, face, underarms or scalp, it is referred to as primary hyperhidrosis.

Generalized

Excessive sweating involving the whole body is termed generalized hyperhidrosis or secondary hyperhidrosis. It is usually the result of another underlying health condition.

What to Expect During Sweat-Reduction Treatment

All injectable and medical-device-based treatments at Skin Vitality are performed by a medical team of fully licensed, highly experienced regulated health-care professionals, including Medical Doctors, Nurse Practitioners, Registered Nurses, and Registered Practical Nurses.

A typical appointment involves:

  1. Cleansing of the treatment area.
  2. Marking a light grid pattern to guide even placement.
  3. Using a fine needle to place very small amounts of Botox just below the surface.
  4. Applying ice or topical numbing agents when appropriate.

Most sessions take approximately 30 minutes depending on the treatment area and clinical plan.

What to Expect After Treatment

Recovery experiences differ, but most treatment plans follow a general pattern:

Immediately After Treatment

  • Normal activities often continue as usual
  • Mild redness or pinpoint swelling may appear in the treated area

Days 2–7

  • Sweat reduction may begin to develop
  • Comfort levels often improve gradually over this period

Around Week 2

  • Full treatment effect is typically reached
  • The treated area may show steadier sweat-control support

In the Following Months

  • Results may continue for several months, depending on the area
  • Treatment longevity is often longest for underarms and shorter for palms or soles

A follow-up appointment may be recommended to assess treatment response and determine if additional support is needed.

Potential Side Effects and Considerations

Side effects vary by person and by treatment area. They may include temporary discomfort, redness, or mild bruising. When treating the palms, temporary grip weakness may occur. All considerations, precautions, and risks are reviewed during a complimentary assessment.

Benefits of Non-Surgical Sweat Reduction

Botox hyperhidrosis treatment plans may help support:

  • Reduced sweating in targeted regions
  • Increased comfort in clothing and daily routines
  • Less reliance on antiperspirants
  • Temporary relief without surgical intervention
  • Sweat-management support across multiple areas of concern

Efficacy and longevity vary from person to person.

FAQ's About Sweat Reduction

A condition involving excessive sweating beyond what is needed for temperature regulation.

 

It temporarily affects the nerve signals that stimulate sweat glands. Sweat reduction varies by area and physiology.

 

Underarms (approved), palms, soles, face, scalp, chest, and other localized regions (off-label).

 

Duration varies by area. Underarm support may last several months; hands and feet may require more frequent maintenance.

 

Initial improvement may begin within 2–7 days, with full development within 2 weeks.

 

Potential side effects are discussed during consultation and vary based on the area treated.

 

Botox injections in the underarms are typically done using a tiny micro-needle. Depending on the patients pain tolerance, there can be a bit of discomfort.

There is no permanent cure, but several non-surgical treatment options—including Botox®—can help manage symptoms. Results vary.
