Re-Evaluating The Role Of Demodex Mite In Skin Bio-Balance
TLDR Demodex mites might help skin balance by eating bacteria, but their role in skin disorders is unclear and may involve other factors.
Demodex mites are human ectoparasites that live in or near pilosebaceous units, with D. folliculorum consuming skin cells and sebum, and D. brevis feeding on gland cells. These mites may contribute to maintaining dermal bio-balance by consuming bacteria or other organisms in the follicular canal. However, it's unclear whether Demodex mites are the cause or result of pre-existing conditions like rosacea and other skin disorders, collectively referred to as demodicosis. The review suggests that other factors, such as immunological imbalance, microbiome alterations, or concurrent infections, may drive the pathogenicity of Demodex mites. Recognizing these underlying causes can aid in early diagnosis and effective treatment of various dermatoses associated with Demodex mites.
