Studies Focus on Angiogenesis' Role

Results of two recent studies provide new understanding of how and when angiogenesis -- the formation of new blood vessels -- may contribute both to the initial development of rosacea and its persistent presence. In a study of skin samples with and without rosacea, taken from biopsies and evaluated under a microscope, Dr. Amal Gomaa and colleagues at Boston University found evidence of angiogenesis in both the blood and lymphatic circulatory systems in skin with rosacea lesions.1

New Study Finds Receptors' Role

New research funded by the National Rosacea Society has found that certain molecular receptors and their activators may play a significant role in producing the redness, visible blood vessels and inflammation of rosacea.

A receptor is a structure in human cells that binds with particular activating substances in the body to trigger certain reactions or responses. Dysfunction of receptors often leads to disease. Accordingly, identification of the mechanisms of these processes, which may then be adjusted, often leads to important therapeutic advances.

NRS Awards New Research Grants to Study Life-Disruptive Disorder

The National Rosacea Society (NRS) has awarded funding for six new studies as part of its research grants program to advance scientific knowledge of potential causes and other key aspects of this chronic and often life-disruptive disorder that affects an estimated 14 million Americans.

ATP May Play Key Role in Rosacea

Results from previous research funded by the National Rosacea Society have led investigators Dr. Richard Granstein and colleagues at the Cornell University Medical School to focus in their current study on adenosine triphosphate (ATP), a natural substance in the body that may play a key role in the flushing, telangiectasia and bumps and pimples of rosacea.

Research Grants Awarded to Study Causes of Little-Known Disorder

The National Rosacea Society announced that five new studies have been awarded funding as part of its research grants program to advance scientific knowledge of this widespread but poorly understood disorder that affects an estimated 14 million Americans.

Scientists Reveal New Advances in Understanding Common Disorder

Medical scientists from around the world reported on their progress in studies funded by the National Rosacea Society (NRS) to uncover potential causes and other key aspects of the disorder during the fifth annual rosacea research workshop, held in conjunction with the annual meeting of the Society for Investigative Dermatology. The NRS conducts the workshop to promote interest in studying rosacea and to share new information from ongoing studies.

New Research Grants Awarded to Advance Knowledge of Rosacea

Five new studies of rosacea have been awarded funding as part of the National Rosacea Society's research grants program to advance scientific and medical understanding of this widespread but poorly understood facial disorder, estimated to affect 14 million Americans.

Medical Scientists Report Advances in Uncovering Mysteries of Rosacea

Researchers reported on continuing progress in the study of potential causes and other key aspects of rosacea during the National Rosacea Society's fourth annual research workshop, held in conjunction with the annual meeting of the Society for Investigative Dermatology.

Research Grants Awarded to Study Common but Little-Known Disorder

The National Rosacea Society announced that new studies of rosacea have been selected for funding as part of its research grants program to support the advancement of scientific knowledge of this poorly understood and often life-disruptive facial disorder.

Study Shows Sun May Affect Blood Vessels

Sun exposure appears to trigger a substance in the body that may lead to the visible blood vessels that often appear with rosacea, according to research funded by the National Rosacea Society and reported at the annual meeting of the Society for Investigative Dermatology.

"Our initial study showed that sunlight may indeed have a role in causing rosacea," said Dr. Marita Kosmadaki, research fellow, Department of Dermatology, Boston University, who presented results of her research with Dr. Mina Yaar, professor of dermatology at Boston University.

Our Mission

The National Rosacea Society is a 501(c)(3) nonprofit organization whose mission is to improve the lives of people with rosacea by raising awareness, providing public health information and supporting medical research on this widespread but little-known disorder. The information the Society provides should not be considered medical advice, nor is it intended to replace

consultation with a qualified physician. The Society does not evaluate, endorse or recommend any particular medications, products, equipment or treatments. Rosacea may vary substantially from one patient to another, and treatment must be tailored by a physician for each individual case. For more information, visit About Us.
