Can scabies mites bite through the stratum corneum?

It is indeed possible for scabies mites to damage the skin's stratum corneum. As parasites living on the surface of human skin, scabies mites primarily feed on skin keratinocytes and excavate tunnels beneath the skin surface to obtain what they need to survive. After the human body is infected with scabies mites, these tiny parasites provoke a series of reactions on the skin. Besides causing an unbearable itching sensation on the skin surface, scabies mites can also stimulate the skin via their secretions, metabolic products, and dead bodies, triggering allergic reactions and aggravating skin inflammation. Under this persistent irritation, the skin's stratum corneum may suffer severe damage, exhibiting symptoms such as redness, lesions, and even excoriation. Therefore, timely prevention and treatment of scabies infestation are crucial for protecting skin health and preventing damage to the stratum corneum.
