Founded in 2003, the International Hyperhidrosis Society is the only global, independent, medically-astute, registered charity dedicated solely to hyperhidrosis.

As a formally recognized Top NonProfit by Guidestar and Great NonProfits, the International Hyperhidrosis is proud to be led by a volunteer Board of Directors. Nearly every member of our board is a recognized medical expert and researcher in the field of dermatology and, specifically, hyperhidrosis.

By choosing to donate to the International Hyperhidrosis Society, you are choosing to improve the lives of those affected by excessive sweating. With your support, the International Hyperhidrosis Society:

  • Creates and delivers award-winning educational and advocacy programs
  • Raises awareness of hyperhidrosis in both the public and healthcare arenas
  • Facilitates access to effective treatments for people around the world
  • Provides information, support, and resources free of charge.  

 Thank you for your support. It is greatly appreciated, and needed. We are sincerely grateful to the generosity of our public and private community for our financial health. All donations are tax-deductible and many employers will match tax-deductible charitable contributions made by their employees, retirees, and employees' spouses. So, please check with your human resources department to see if your contribution can grow exponentially!

The International Hyperhidrosis Society's financial management plan has transparency, checks and balances, and the expertise of outside professionals keeping it on track. We use an outside accounting firm that specializes in non-profits to prepare certified financial statements including IRS Form 990 (the IHHS' tax return). The IHHS' Form 990 is available at
