New clues to help unlock the mystery of rosacea were identified in a recent study in which researchers used advanced technology to evaluate the skin of patients successfully treated with pulsed dye lasers (PDL) or intense pulsed light (IPL).

"We are pleased to see interesting findings in this small pilot study that not only help reveal the underlying disease process, but may also provide a basis for developing more targeted therapy in the future," said Dr. Nancy Samolitis, visiting instructor in dermatology at the University of Utah and investigator in the NRS-funded study.

The National Rosacea Society (NRS) has awarded five new research grants to advance scientific knowledge of the potential causes and other key aspects of this chronic and potentially devastating disorder that affects an estimated 14 million Americans.

"We are very pleased that a growing number of high-quality research proposals are now being received," said Dr. Jonathan Wilkin, chairman of the Society's medical advisory board, which reviews each grant application and selects for funding those believed most likely to yield important results.

While medications have long been used to keep the inflammation -- the bumps (papules), pimples (pustules) and some of the related redness -- of rosacea at bay, many dermatologists have found certain types of lasers and light sources offer important options for addressing components of the disorder that are more difficult to treat.
