What axillary hyperhidrosis is.
Axillary hyperhidrosis is excessive underarm sweating that goes beyond what your body needs to cool itself, and for most people it is a primary condition, meaning it is not a symptom of another illness.
Normal sweating is your body regulating temperature. Hyperhidrosis is the sweat glands firing far more than that, often regardless of heat or activity, so you soak through shirts, ruin fabrics, and change clothes more than once a day. In Miami, the heat and humidity make an already frustrating problem feel constant. It is common, it is not caused by poor hygiene, and it responds well to treatment.
Botox for underarm sweating targets the mechanism directly and is a settled, evidence-backed option.
Does Botox stop underarm sweating? How it works.
Yes. Botox stops underarm sweating by temporarily blocking the nerve signal (acetylcholine) that tells your sweat glands to switch on, and it is FDA-approved for severe primary axillary hyperhidrosis.

Sweat glands are activated by a nerve chemical called acetylcholine. Botox blocks that signal at the treated site, so the glands in your underarm simply stop overproducing sweat. It does not affect sweating anywhere else on your body, and it does not cure the condition; it reliably manages it for months, and the treatment is repeatable.
That FDA approval matters. Botox (onabotulinumtoxinA) is specifically approved for severe primary axillary hyperhidrosis, so treating underarm sweating with it is an on-label, well-studied use.
Botox (onabotulinumtoxinA) is FDA-approved for severe primary axillary hyperhidrosis, excessive underarm sweating, and works by temporarily blocking the nerve signals that switch on the sweat glands.
What the underarm Botox visit involves.
Underarm Botox is a quick in-office visit: about 15 to 30 minutes, a series of tiny injections across each underarm with a very fine needle, and little to no downtime.

Kelly cleans and maps each underarm, then places a grid of small, shallow injections. Numbing cream or ice keeps it comfortable, and the needle is fine enough that most patients describe it as quick pinches. You can drive yourself home and return to work or the beach the same day. Afterward, skip antiperspirant, intense exercise and heat for about 24 hours.
How long it lasts, and how many units.
Sweating usually drops within a few days, reaches full effect by about two weeks, and lasts roughly 4 to 6 months; dosing is individualized, commonly around 50 units per underarm per the FDA labeling.
Most patients come back about twice a year for a maintenance treatment as the effect gradually wears off. Your exact dose depends on how much you sweat and the size of the area, and Kelly confirms it at your consultation. A full treatment is commonly around 100 units total across both sides. Some clinics advertise "up to 12" or "14 months," but 4 to 6 months is the realistic, evidence-based range for underarm Botox.
What it costs in Miami Beach, and does insurance cover it.
Botox for underarm sweating is priced per unit, generally around $13 to $18 a unit; because a full treatment commonly uses about 100 units, a typical session runs about $1,300 to $1,800, and insurance sometimes contributes for documented severe cases.
You pay for the units you actually receive, confirmed in writing before treatment. Because Botox is FDA-approved for severe primary axillary hyperhidrosis, some insurance plans contribute when severe underarm sweating is documented and first-line options, like prescription-strength antiperspirant, have not worked. Coverage varies by plan, and Kelly can walk you through what your insurer is likely to want to see.
Botox or miraDry® for underarm sweating: which is right for you.
Botox is a quick, repeatable injection that lasts about 4 to 6 months and is sometimes insurance-eligible; miraDry is a device treatment that aims for a permanent reduction in one or two sessions but costs more upfront and involves more recovery.
South Florida Face and Body provides the Botox approach, and Kelly will tell you honestly if a permanent device treatment elsewhere would serve you better. For most people who want relief this summer without a big commitment, underarm Botox is the straightforward place to start.
Why Miami makes this worth it.
Miami Beach is hot and humid nearly year-round, so underarm sweating here is a daily problem, not a seasonal one, which is exactly when a treatment that keeps you dry for months earns its place.

Sweat marks show up in every setting South Beach runs on: rooftop dinners, events, dating, the beach, back-to-back meetings in the heat. Underarm Botox lets you wear what you want and stop planning your day around sweat. It also pairs naturally with the other neuromodulator treatments in Miami Beach Kelly offers, so it is easy to combine with a Botox treatment in Miami Beach for lines if that is also on your list.
