The market for aesthetic medical devices gained some ground during the 2nd quarter, a MassDevice.com analysis shows, although healthy sales growth didn’t necessarily translate into healthy bottom lines for all comers.

Two companies, PhotoMedex (NSDQ:PHMD) and Cynosure (NSDQ:CYNO), saw top-line gains of 74% and 50%, respectively, and were 2 of only 3 companies on the list to log black ink during the quarter with (Cynosure and Photomedex swinging from red to black during the period).

The revenue growth for the sector is due to 3 main factors, according to Leerink Swann analyst Richard Newitter: Stable purchasing trends and expectations; better access to credit for doctors, "which can be an important factor in physicians’ AED purchasing decisions,"; and steady procedure volume growth, "a potential leading indicator for AED spending."
