Botox for excessive sweating (hyperhidrosis)

Botox for excessive sweating (hyperhidrosis) is one of the localized treatments used for this concern. We administer botulinum toxin (Botox) to areas containing sweat glands to reduce sweating. We most often treat the underarms, and the palms and soles are also treatment areas. During the consultation, you can describe where sweating bothers you and which tasks it makes difficult.

Wet underarms on clothing or a pen slipping because of moisture on the palm are examples of how excessive sweating can be described. Its impact may vary according to the person’s work and the area affected. Sharing these practical difficulties during the examination provides different information from stating only the size of the wet area.

Effect on the sweat glands

Sweat glands work in response to signals from nerves. Botox reduces the nerve transmission that stimulates these glands in the treated area. The target for sweat production is defined by the area of skin receiving injections.

In wrinkle treatment, Botox targets contraction of a specific facial expression muscle. Sweating treatment acts on the nerve signals reaching the glands. This difference affects the layer where injections are placed and the distribution of injection points.

Eccrine glands lie within the skin, with ducts that open onto its surface. Their secretions contribute to temperature regulation, and these glands are densely distributed on the palms, soles, and underarms. The examination includes questions about the circumstances in which sweating occurs and its distribution. Sweating in a hot environment and localized wetness that is noticeable even in cool surroundings may suggest different histories.

Sweat gland activity is not controlled in the same way as a voluntary muscle movement. Heat and emotional stimuli can contribute to the sweating response through the nervous system. Botox treatment targets the nerve signals reaching these glands. Removing glands or filling sweat ducts with a substance is not part of its mechanism.

Investigating the cause of sweating

Excessive sweating may be concentrated in particular areas or spread across the body. If it is linked to another condition or medication, that cause is taken into account in the treatment decision. The distribution of the concern and health history are clarified before discussing suitability for localized Botox.

You can describe how the sweating began, which circumstances make it worse, and whether family members have similar concerns. Previous sweating treatments and current medications are also part of the history. These details provide clues to causes that wetness on the hands or underarms alone cannot reveal.

Localized excessive sweating that is not explained by another disease or medication is called primary hyperhidrosis. Secondary hyperhidrosis describes sweating related to another condition. Depending on the health history, thyroid function, metabolic diseases, or current treatments may be investigated. Whether sweating is confined to a limited area or widespread helps guide this investigation.

The consultation includes questions about whether both underarms are affected similarly and whether the palms and soles also sweat. You can also mention sweating during sleep or a change in your usual sweating pattern. These details may call for investigation of the cause before an injection area is marked. How the concern arises contributes to the treatment decision as well as where it occurs.

Underarms, palms, and soles

The wet area of clothing at the underarm may not exactly match the boundaries of sweating on the skin. Sweat spreading through fabric can create a broad wet patch. The examination focuses on the distribution across the skin. The boundary of the hair-bearing area alone does not show where sweat glands are active.

When describing palm sweating, you can share difficulties with writing, holding paper, or gripping hand tools. Sweating on the inner surfaces of the fingers and the center of the palm may have different distributions. The structure of hand skin and its relationship to the muscles beneath it are considered in the plan. Injection sites on the palm are selected according to the hand’s own anatomy.

The location of sweating on the soles is examined together with concerns about wet shoes and socks. The thickness and structure of sole skin differ from those of underarm skin. The examination also checks for other skin disease or active infection. Moisture inside footwear is interpreted alongside the skin examination findings.

Examination and suitability

When someone seeks localized Botox, the need for further testing depends on the distribution of sweating and their health history. Findings that suggest another condition may prompt investigation in that direction. Results of previous investigations can help clarify the cause during the new consultation.

We do not administer Botox for sweating during pregnancy or breastfeeding. When describing the areas that sweat, you can also let us know if you are pregnant or breastfeeding.

Sweating does not affect everyone’s work in the same way. Moisture on the palm dampening paper, a hand tool slipping, or clothing frequently becoming wet describe different needs. The examination also includes questions about how the hands are used at work. This information helps clarify functional expectations for palm treatment.

An iodine-starch color test may be used when needed to show the sweating area. Areas of skin with sweat become visible through a color change. This helps identify the boundaries of the treatment area. The distribution shown by the test is interpreted together with health history and examination to investigate the cause of sweating.

An active infection at the treatment site prevents treatment there. Diseases affecting communication between nerves and muscles, medications, and known allergies to treatment ingredients are included in the suitability decision. An uncontrolled systemic disease requires assessment first. If sweating is suspected to be medication-related, the medication should not be stopped on the person’s own initiative.

During the consultation, you can mention antiperspirant products and treatments you have previously used. The areas they were used for and how the concern changed inform the new treatment decision. Treatments for another condition may also be related to the sweating pattern. Records, if available, can be added to the sweating history.

Underarm and palm sweating may cause different levels of difficulty in the same person. Someone seeking help for wet hands may not want treatment for underarm sweating. You can describe which area is your priority during the consultation. The treatment decision is based on the distribution and skin structure of that area.

Botox treatment

We identify the boundaries of sweating and apply Botox to these areas with very fine needles. We direct the injections to the skin areas containing sweat glands. During the consultation, we explain the area selected for your underarms, palms, or soles.

Injections are distributed across different points within the area containing sweat glands. Their placement is planned to cover the skin surface where sweat emerges. As the sweating map widens or changes shape, the distribution of points is adjusted to that area.

Sweating treatment targets the skin area containing the nerve endings that stimulate the glands. Skin thickness and the underlying anatomical structures affect the layer in which treatment is delivered. These locations are considered separately when planning for the center of the palm and the inner surfaces of the fingers. A treatment map drawn for a facial expression muscle does not describe the anatomy of the hand or underarm.

A fine needle allows an injection at a selected point within the skin. The blunt-tipped cannula used for fillers is a thin tube that distributes material along a particular tissue plane. Because Botox for sweating does not aim to add volume, the injection technique is explained in relation to the location of sweat glands.

Sweat odor and sweat amount

The amount of sweat and its odor can be described as separate concerns. Microorganisms on the skin surface and the composition of secretions also contribute to odor. If odor is the main concern, its relationship to wetness is investigated during the examination. Botox for sweating aims to reduce sweat secretion in the treated area.

The underarms contain apocrine glands associated with hair follicles as well as eccrine glands. These glands differ in their secretions and structure. Odor, wetness, and other findings on the skin surface are identified separately during the examination. This helps clarify which concern is being considered for injections targeting sweat secretion.

Choosing a sweating treatment

Antiperspirant products aim to reduce sweat secretion. Deodorants address odor. When discussing which type of product someone has used, its intended purpose can be explained as well as its name. Having tried only an odor-focused product while seeking help for wetness provides different information in the medical history.

Iontophoresis is among the methods used for hand and foot sweating. In this method, a device delivers a low-level electrical current while the hands or feet are in contact with water. Botox is delivered by injection into selected skin areas. Which option may be considered depends on the area that sweats, health status, and previous treatment information.

A limited sweating area in the underarm and sweating spread across the torso cannot be planned as the same treatment area. Localized injections address a defined skin surface. For widespread sweating, the underlying cause and treatment options for it are investigated separately. Identifying a link to another disease may require a treatment approach that extends beyond targeting only the wet area.

A previous treatment for underarm sweating does not mean that the same treatment has been tried for the palms. During the consultation, the methods tried for each area can be specified separately. The spread of wetness and its impact on work are described alongside this record. This allows Botox for sweating to be considered in relation to the needs of a particular area rather than as a general request for a procedure.

Planning with other treatments

If Botox is being considered for facial lines that become noticeable with expression, a separate examination of muscle movement is performed. For lines visible when the face is at rest, skin structure is also taken into account. In Botox for sweating, the distribution and cause of sweat secretion are central to treatment. Even when both concerns are discussed in the same consultation, the anatomical targets are defined by their own findings.

Fillers address volume and shape, while biostimulators target the tissue’s collagen response. Reducing nerve signals to sweat glands is outside the scope of these treatments. Any expectations about facial aesthetics are explained through a separate tissue examination from the sweating concern.
