A lot of rashes have grown on my face. I don't know whether it is eczema, milk moss or prickly

When rash appears on the face, it needs to be judged in combination with skin lesions. For example, eczema is mainly distributed symmetrically, and it will be accompanied by obvious itching symptoms. In addition, milk moss is eczema. And prickly heat is mainly distributed on the chest, back and neck, and it will also be accompanied by more sweating.
