Hyperhydrosis (Excessive Sweating)

What is hyperhidrosis?

Hyperhidrosis is a medical condition that causes excessive sweating beyond what the body needs to regulate temperature. It often affects the underarms, hands, feet, or face and can interfere with daily activities.

What causes hyperhidrosis?

In most cases, it’s due to overactive sweat glands with no underlying health issue (called primary hyperhidrosis). Less commonly, it can be linked to medical conditions or medications (secondary hyperhidrosis).

How do I know if I have hyperhidrosis?

Signs include frequent sweating that soaks through clothing, dripping sweat from hands or feet, or sweating that happens even when you’re not hot, active, or stressed.

How does Zand Dermatology treat hyperhidrosis?

We use Botox injections to block sweat gland activity.

How effective are Botox® injections for hyperhidrosis?

Botox® is FDA-approved for excessive underarm sweating and can also be used on hands and feet. Results typically last 4–6 months, with many patients experiencing a dramatic reduction in sweat.

Is the treatment safe?

Yes. Treatments like Botox® are well-studied and considered safe when performed by a board-certified dermatologist like Dr Zand.
