Merz Acquires ON Light Sciences

Merz North America has acquired ON Light Sciences, maker of the DeScribe Transparent PFD (perfluorodecalin) patch for laser tattoo removal. The DeScribe patch is placed over tattoos prior to irradiation, allowing physicians to treat tattoos more efficiently by enabling rapid multiple laser passes in a single treatment session. It also provides optical clearing of tissue, protects the epidermis and inhibits potentially infectious back-splatter and fumes.

“The addition of ON Light Sciences’ innovative technology allows us to better meet the needs of aesthetic practices that focus on energy-based devices,” said Philip Burchard, CEO of Merz Pharma Group. “We have a vision to be the most innovative company in aesthetics, and this acquisition clearly complements our growing and diversified global portfolio, which includes the Ultherapy and Cellfina devices.”

“We look forward to joining Merz and expanding awareness and use of the DeScribe Transparent PFD Patch. We share Merz’s commitment to innovation that directly and positively impacts patient health and welcome the opportunity to be part of its strong product lineup,” said David Sell, president and CEO of ON Light Sciences.
