Tria Beauty (formerly known as SpectraGenics), the Pleasanton, Calif. maker of a device that uses lasers for hair removal, has raised $30 million in its fifth round of financing. Unlike similar devices, Tria's hair removal system has been cleared for home use. While it has been sold for some time in Japan and some European countries, the device was also recently approved for the United States by the FDA. To date, laser hair removal has been an expensive procedure performed by specialists, and its time-intensive nature has caused it to mainly be used for small areas. The cost and other limitations should drop if the devices become common in homes or beauty salons, which will also provide a larger market for Tria to sell into. The $30 million funding was led by Aisling Capital and Vivo Ventures. Existing investors De Novo Ventures and Technology Partners also joined. Tria's last round was for over $20 million.
