Research suggests human demodex, a microscopic mite, is potential contributor to rosacea. Numerous studies have found it appears in higher numbers on the skin of people with rosacea, particularly on rosacea bumps and pimples (papulopustular rosacea).
For some time, it has not been clear whether the mites actually cause the rosacea or whether a person with rosacea's immune system reacts sensitively to them. However, a new study suggests altered immune response may be involved. A new study from the National University of Ireland-Maynooth found bacteria present on the mite (Bacillus oleronius) caused an immune response in rosacea patients.
Typically, treatment to reduce the mites/bacteria (Metronidazole) reduces skin inflammation and relieves rosacea. In the herb world, we use herbs like cat's claw, pau d'arco, and goldenseal infused in a topical aloe vera gel (Immune Support gel) to keep skin balanced, cool and calm.
