All about Rosacea and the role of Demodex mites: symptoms and treatments

Rosacea is a skin condition characterized by redness, pimples and visible blood vessels, mainly on the face. Studies link Demodex mites to the worsening of Rosacea symptoms. In this article we delve deeper into the world of two closely related mites: Demodex folliculorum and Demodex brevis and their impact on Rosacea. The latest treatment methods and prevention strategies are also briefly discussed.

The two Demodex mites and Rosacea: An underlying connection

The Demodex folliculorum mite, commonly known as the skin mite, is found in hair follicles and sebaceous glands and is mainly found around the eyes and on the face. An overpopulation of this mite is often associated with eye inflammation (Demodex blepharitis) and the development of Rosacea symptoms such as redness, itching and pimples. The Demodex brevis mite, located deeper in the skin, contributes to inflammation and can worsen the condition.

Treatment of Rosacea: breakthrough and innovations

Do you suffer a lot from inflamed and irritated eyes and nothing seems to help? Then there is a new method. Recent research has shown that Lotilaner Ophthalmic Solution is a promising treatment for Rosacea-related eye inflammation. The eye drop solution containing Lotilaner is sold under the brand name Xdemvy and was approved as a drug by the US FDA in July 2023. Interestingly enough, Lotilaner is also used for pets as a parasiticide to combat fleas and ticks and is therefore also effective against skin mites.

Future of Rosacea Treatments

With a growing understanding of the role of Demodex mites in Rosacea, researchers continue to develop new treatments. Acaricides, in addition to traditional medications and creams, are now showing good results in reducing inflammation. The skin condition can also greatly improve after treatments with both IPL and laser therapy.

Natural remedy and preventive care

So before you start taking medication through your GP, it is advisable to visit a skin therapist. The skin therapist knows a lot about Rosacea and is aware of the latest developments. While Tea Tree oil and improved eyelid hygiene are often recommended on the internet as home remedies for Demodex mites, caution is advised. Because Tea Tree oil is irritating, especially for sensitive skin. But a balanced skincare routine as part of state-of-the-art medical advice can be your key to managing your Rosacea symptoms.

The role of Demodex mites in Rosacea is still a subject of research and debate among dermatologists and researchers. Some studies suggest a correlation between higher densities of Demodex mites on the skin and the symptoms of Rosacea, especially in the forms of Rosacea characterized by pimples and bumps. These studies imply that the mites or the bacteria the mites carry can trigger an inflammatory response that contributes to the symptoms of Rosacea. On the other hand, there are also studies that find no convincing evidence that the presence of Demodex mites is a direct cause of Rosacea. This means that while Demodex may be present in increased numbers in people with Rosacea, they are not necessarily the underlying cause of the condition. It may be that Rosacea makes the skin more susceptible to a higher population of these mites, rather than the mites causing the rosacea.
