Which of the following can be a cause of Rosacea?

Demodex folliculorum mites are often considered a potential contributing factor in the development of rosacea. These mites reside naturally on human skin and can influence skin conditions, especially in individuals with rosacea. Research indicates that those with this skin condition may have an increased density of these mites, suggesting a possible role in exacerbating the symptoms.

The other options present factors that can contribute to skin issues but are not specifically linked to the pathogenesis of rosacea like the presence of Demodex mites. Increased oil production typically relates to acne or other forms of dermatitis rather than rosacea directly. Similarly, while exposure to UV light can result in skin damage and may exacerbate various skin conditions, it is not established as a primary cause of rosacea. Therefore, focusing on the role of Demodex folliculorum mites highlights a recognized connection in rosacea’s etiology, making this the most accurate answer.
