Rosacea is a chronic inflammatory skin condition that affects millions of people worldwide. While the exact cause of rosacea is still not fully understood, recent research suggests that a bug called Demodex folliculorum may play a significant role.

Demodex folliculorum is a type of mite that lives in the hair follicles of human skin. Everyone has these tiny bugs living on their skin, but people with rosacea have been found to have higher populations of Demodex mites in their skin.

According to a study published in the Journal of Medical Microbiology, Demodex mites are believed to trigger an immune response in the skin that leads to the formation of rosacea symptoms such as red flushing, visible blood vessels, and acne-like bumps.

Interestingly, Demodex mites are not the only potential cause of rosacea. Other factors that may contribute to the condition include genetics, sun exposure, alcohol consumption, spicy foods, and hormonal imbalances.

In the words of Dr. Linda Stein Gold, a renowned dermatologist and expert in the field of rosacea, “Although we do not yet have a cure for rosacea, through ongoing research, we are learning more and more about the causes of this condition and how we can manage its symptoms.”

Here is a table summarizing some interesting facts about rosacea:

Dr. Dray explains in this video about demodex mites, which are part of our natural skin flora and usually harmless. However, for some people with impaired immune systems or skin conditions like rosacea and blepharitis, they can become problematic. While not typically diagnosed through specific testing, certain treatments like lid hygiene can be used to address the issue for those experiencing symptoms. Dr. Dray also discusses the importance of gentle cleansing twice a day to remove oils and selecting lightweight, oil-free moisturizers to prevent inflammation and acne-like breakouts. She also mentions potential prescription treatments, such as cilantro, which have proven significant in treating rosacea, and how IPL treatment can help reduce the burden of demodex mites but is not evidence-based.
