Research shows rosacea caused by skin mites

August 31, 2012 Updated Aug 31, 2012 at 2:32 PM CDT

GALWAY, Ireland -- Bacteria from tiny mites living on the skin may be responsible for the skin condition rosacea.

Rosacea causes redness and swelling of the skin, usually around the cheeks, nose, and chin and often strikes women in middle age.

Previous studies revealed rosacea is triggered by bacteria that live in skin mites, which increase with age and skin damage.

Now, scientists have identified that the bacteria living in the digestive tracts of these mites activates the swelling and pain.

These findings may help develop a more specific antibiotic to treat rosacea or a method of controlling these skin mites.

This study was led by researchers at National University of Ireland and is published in the 'Journal of Medical
Microbiology'.
