Google Launches a Dermatology AI App in EU

Billions of times each year, people turn to Google’s web search box for help figuring out what’s wrong with their skin. Now, Google is preparing to launch an app that uses image recognition algorithms to provide more expert and personalized help. A brief demo at the company’s developer conference last month showed the service suggesting several possible skin conditions based on uploaded photos.

Machines have matched or outperformed expert dermatologists in studies in which algorithms and doctors scrutinize images from past patients. But there’s little evidence from clinical trials deploying such technology, and no AI image analysis tools are approved for dermatologists to use in the US, says Roxana Daneshjou, a Stanford dermatologist and researcher in machine learning and health.

Many don’t pan out in the real world setting,” she says.

Google’s new app isn’t clinically validated yet either, but the company’s AI prowess and recent buildup of its health care division make its AI dermatology app notable. Still, the skin service will start small—and far from its home turf and largest market in the US. The service is not likely to analyze American skin blemishes any time soon.

At the developer conference, Google’s chief health officer, Karen DeSalvo, said the company aims to launch what it calls a dermatology assist tool in the European Union as soon as the end of this year. A video of the app suggesting that a mark on someone’s arm could be a mole featured a caption saying it was an approved medical device in the EU. The same note added a caveat: “Not available in the US.”

Google says its skin app has been approved “CE marked as a Class I medical device in the EU,” meaning it can be sold in the bloc and other countries recognizing that standard. The company would have faced relatively few hurdles to secure that clearance, says Hugh Harvey, managing director at Hardian Health, a digital health consultancy in the UK. “You essentially fill in a form and self-certify,” he says. Google’s conference last month took place a week before tighter EU rules took effect that Harvey says require many health apps, likely including Google’s, to show that an app is effective, among other things. Preexisting apps have until 2025 to comply with the new rules.
