Who is most susceptible to demodex infestation?

Individuals with a compromised immune system are more susceptible to demodex infestation because their body's natural defense mechanisms are weakened. Demodex mites are a type of microscopic mite that normally live on skin and hair follicles without causing any issues in healthy individuals. However, when a person's immune system is not functioning optimally, such as due to illness, stress, or certain medications, the balance between the host and these mites can be disrupted. This can lead to an overpopulation of demodex mites, resulting in skin issues such as inflammation, irritation, and conditions like rosacea.

While oily skin can accommodate more mites and poor skincare habits can exacerbate conditions that may lead to an outbreak, the primary factor in susceptibility is the state of the immune system. Healthy adults typically maintain a balance that prevents mite overgrowth, and individuals without a skincare routine might not initially be at increased risk unless other factors are present. Therefore, the critical factor here is the immune system’s integrity rather than personal hygiene or skin type.
