Excessive Sweating
Doesn't Have To Control Your Day.
Sweating is normal. Sweating through clothing while sitting in an air-conditioned room, avoiding handshakes because your palms are soaked, or constantly dealing with damp feet may be something different.
Hyperhidrosis is excessive sweating beyond what the body needs for normal temperature regulation. In appropriately selected patients, botulinum toxin can temporarily reduce sweat production within a treated area by interrupting the nerve signaling that activates sweat glands.
When it starts changing how you live.
Changing shirts during the day.
Avoiding certain colors or fabrics.
Feeling uncomfortable shaking someone's hand.
Slipping inside shoes because your feet stay wet.
Sweating heavily when you are not hot or exercising.
Those are the kinds of patterns that can point toward hyperhidrosis rather than ordinary perspiration.
There is normal sweating - and then there is excessive sweating.
The first step is determining whether the pattern looks like primary focal hyperhidrosis or whether sweating could be a symptom of something else.
Sweating is the condition.
Primary focal hyperhidrosis typically affects one or more specific areas, often the underarms, palms or soles, and can occur even when the person is not overheated.
Sweating may be a symptom.
New generalized sweating, night sweats or a major change in sweating pattern can sometimes be associated with medications, endocrine or metabolic conditions, menopause, infection or other medical causes. When the pattern appears secondary, identifying the cause matters more than simply treating the sweat glands.
Underarms, palms + soles require different treatment conversations.
The anatomy, evidence, comfort considerations and risks differ by treatment area.
Underarm Sweating
Axillary hyperhidrosis is the most established botulinum toxin treatment for excessive sweating. BOTOX is FDA approved for severe primary axillary hyperhidrosis that is inadequately managed with topical agents.
Sweaty Palms
Botulinum toxin has been studied for palmar hyperhidrosis and may substantially reduce sweating in selected patients. Treatment requires additional counseling because injections can be uncomfortable and temporary hand weakness can occur.
Sweaty Feet
Botulinum toxin has also been used for plantar hyperhidrosis. Treatment of the soles can be uncomfortable because plantar skin is highly sensitive, and the evidence base is smaller than for the underarms.
The sweat gland does not disappear. Its signal is temporarily reduced.
Nerve Signal
Autonomic nerves normally communicate with eccrine sweat glands.
Acetylcholine
The nerve releases acetylcholine, a chemical messenger involved in activating sweat production.
Botulinum Toxin
Treatment temporarily inhibits acetylcholine release from selected nerve endings within the injected area.
Less Sweat
With less signaling reaching the treated glands, sweat production decreases within that specific area.
Before treating the sweat, we want to understand the pattern.
Not everyone who sweats excessively should automatically receive injections.
Focal Or Generalized?
Longstanding sweating limited to the underarms, palms or soles suggests a different pattern from sudden whole-body sweating or drenching night sweats.
New Or Longstanding?
A significant new change in sweating pattern may warrant further evaluation before treatment.
Medications + Health
Medications, endocrine disorders, metabolic disease, menopause and other health factors can influence sweating.
Impact On Daily Life
Treatment is most relevant when sweating creates meaningful occupational, social, clothing, footwear or quality-of-life problems.

Typical Hyperhidrosis Treatment Investment.
The amount of treatment varies substantially by treatment area, anatomy and the size of the hyperhidrotic area.
Treatment starts at $900. Exact investment depends on the area treated, anatomy, treatment extent, product and individualized treatment plan.
The goal is localized sweat reduction - not stopping normal sweating everywhere.
Treatment reduces sweating within the injected area while the body's untreated sweat glands continue functioning.
Onset
Many patients begin noticing decreased sweating during the first week, with the response continuing to develop thereafter.
Underarms
Clinical trials of axillary BOTOX reported a median response duration of approximately 201 days, although individual duration varies.
Hands + Feet
Response and duration vary by treatment area and patient. Published experience generally describes temporary improvement lasting several months.
Maintenance
Treatment is temporary. Repeat treatment can be considered when sweating returns and the patient remains an appropriate candidate.
Treatment area changes the risk discussion.
Botulinum toxin is a medical treatment. Patient selection, treatment area and anatomy matter.
Underarms
Temporary injection-site discomfort, tenderness, redness, swelling or bruising may occur.
Palms
Temporary weakness of intrinsic hand muscles or reduced pinch strength has been reported and is an important part of counseling before palmar treatment.
Soles
Plantar treatment can be particularly sensitive. Comfort planning is important, and the evidence base is smaller than for axillary treatment.
When sweating deserves a different evaluation.
New generalized sweating, drenching night sweats or a major unexplained change in sweating should not simply be assumed to be primary focal hyperhidrosis. Appropriate medical evaluation may be recommended before elective treatment.
Hyperhidrosis is a well-studied non-cosmetic use of BOTOX.
The strongest evidence applies to primary axillary hyperhidrosis. Evidence also supports palmar treatment, while plantar evidence is more limited.
Primary Axillary Hyperhidrosis
BOTOX is FDA approved for severe primary axillary hyperhidrosis that is inadequately managed with topical agents.
REVIEW FDA LABELINGAxillary Sweat Reduction
A multicenter randomized placebo-controlled trial reported substantially greater sweat reduction with botulinum toxin treatment than placebo.
READ THE STUDYDuration + Quality Of Life
A longer-term randomized study reported improvements in hyperhidrosis severity and activity limitations, with median treatment effect lasting roughly six to seven months in the studied axillary groups.
READ THE STUDYSweaty Hands
Clinical studies support sweat reduction in palmar hyperhidrosis while also identifying temporary hand weakness as a treatment-specific risk.
READ PALMAR STUDYCommon questions about treatment for excessive sweating.
What is hyperhidrosis?
Hyperhidrosis is excessive sweating beyond what is needed for normal temperature regulation. Primary focal hyperhidrosis commonly affects localized areas such as the underarms, palms or soles.
How do I know if I sweat too much?
Consider whether sweating occurs when you are not hot or exercising and whether it interferes with clothing, work, social interaction, handshakes, footwear or daily activities.
Can excessive sweating be caused by another medical condition?
Yes. Secondary hyperhidrosis can be associated with medications, endocrine or metabolic disorders, menopause, infection and other medical causes. New generalized sweating or significant night sweats may warrant medical evaluation rather than automatically proceeding with injections.
How does Botox reduce sweating?
Botulinum toxin temporarily reduces acetylcholine release from selected nerve endings within the treated area, decreasing the signaling that activates eccrine sweat glands.
Is Botox FDA approved for excessive sweating?
BOTOX is FDA approved for severe primary axillary hyperhidrosis that is inadequately managed with topical agents. Treatment of the palms or soles with botulinum toxin is off-label.
Can Botox treat sweaty hands?
Botulinum toxin has been studied for palmar hyperhidrosis and may substantially reduce sweating in selected patients. This is an off-label use, and temporary hand or finger weakness is an important potential risk.
Can Botox treat sweaty feet?
Botulinum toxin has also been used off-label for plantar hyperhidrosis. Evidence is more limited than for underarm treatment, and injections can be more uncomfortable because of the sensitivity of plantar skin.
Does hyperhidrosis treatment hurt?
Underarm injections are generally better tolerated than treatment of the palms or soles. Comfort strategies can be individualized according to treatment area and patient sensitivity.
How quickly does treatment work?
Many patients begin noticing decreased sweating within approximately one week. Response continues to develop over the following days.
How long does treatment last?
Duration varies by patient and treatment area. Major axillary trials reported a median response of approximately 201 days. Treatment of the palms and soles may have different response patterns.
Will I start sweating more somewhere else?
Compensatory sweating is most strongly associated with surgical sympathectomy rather than localized botulinum toxin treatment. Individual sweating patterns can still vary.
Can Botox cause hand weakness?
Yes. Temporary weakness of intrinsic hand muscles or reduced finger pinch strength has been reported after palmar treatment.
How much does Hyperhidrosis treatment cost?
Hyperhidrosis treatment at Bolus starts at $900. Exact investment depends on the treatment area, extent and individualized treatment plan.
Do you accept insurance for Hyperhidrosis treatment?
No. Bolus Med Spa does not accept or bill insurance. HSA or FSA cards may be accepted when permitted by the patient's plan. Bolus does not obtain prior authorizations or complete reimbursement paperwork.
Start with where sweating is affecting you most.
Tell us what you'd like to change or improve. We can help you understand whether your sweating pattern sounds like something that should start with a Bolus assessment.
The same drug can be used for a very different treatment goal.
In cosmetic treatment, neuromodulators temporarily reduce selected facial muscle activity. In hyperhidrosis, the therapeutic target is the nerve signaling that activates sweat glands.
You do not have to plan your day around sweat.
If excessive underarm, hand or foot sweating is interfering with clothing, work, confidence or daily life, start with an assessment. We will evaluate the pattern and determine whether neuromodulator treatment is an appropriate option.
