Iontophoresis machine for at-home treatment of excessive sweating.

From a patent-pending technology to a certified Iontophoresis medical device for treatment of excessive sweating at-home.

We applied our design and technical expertise to redesign and develop an easy-to-use consumer product using DermaDry technology. Our team redesigned the interface and the entire apparatus for safe, comfortable use.

We made sure that the final design would pass Health Canada and FDA certification and could be manufactured at a low enough cost to be affordable for consumers.


Industry / Product Type


Dermadry® medical device redesigned for consumers receives Health Canada and FDA certification.

Using iontophoresis to treat hyperhydrosis (excessive sweating) was known to be effective, but no certified, user-friendly, affordable product was available on the market. We provided the user experience design and engineering expertise that the Dermadry team needed to transform their rough prototype and reassure investors.

Strategy & Design

Dermadry initially asked for help redesigning their product interface and receiving certification. Using our experience with medical devices, usability, and design, our team demonstrated that the entire apparatus needed to be redesigned to help Dermadry reach its goal of successfully launching this device on the consumer market.

Since the device was intended to be for home use, the interface needed to be highly intuitive and really easy to use. Plus, it also had to be cost efficient, sleek, and consumer friendly.


Multiple criteria had to be met at the same time, including user comfort, usability, and affordability. The device had to provide maximum comfort since the technology directs a small current through the user’s skin. As with all projects, we used a collaborative approach. Our teams worked together to take advantage of the extensive market and end-user knowledge provided by Dermadry.

Their founder personally tested the design and gave feedback to evaluate the device as a user. He worked with our teams to ensure that the current was effective but not unpleasant.


Our engineering and design teams worked closely together to incorporate the patent-pending technology into a highly intuitive, non-invasive medical device. Safety and user comfort were primary concerns, requiring much analysis from both engineering and design, along with user feedback.

Our engineering and software development teams worked in tandem to develop the firmware and hardware required to make the device work as envisioned in the design phase.

In addition to their expertise, NOVO provided us with excellent communication throughout the entire process. They also made the most of every minute of our strict timeline. Working with NOVO has ensured a solid foundation for future product development.
