The Art of Lasting Comfort
Botox for Hyperhidrosis
A focused treatment for excessive sweating, helping you stay dry, comfortable, and confident without relying only on topical products.
What it is
FDA-approved sweat control for severe underarm hyperhidrosis.
Botox, also known as onabotulinumtoxinA, is FDA-approved for severe primary axillary hyperhidrosis when excessive underarm sweating is not controlled by topical treatments.

Botox temporarily blocks acetylcholine, the chemical signal that tells sweat glands to activate. When shallow injections are placed across the mapped area, overactive sweating can be dramatically reduced.
Mapped for sweat patterns
Underarms are the most common treatment area, though palms and soles may be discussed depending on provider evaluation and treatment goals.
Helps reduce visible sweat patches, clothing changes, and stress about sweating.
One treatment may provide many months of dryness for appropriate candidates.
