What is the grain like prickly heat on the face

The small particles on the face like prickly heat may be a kind of prickly heat or eczema caused by other reasons. In addition to prickly heat and eczema, there may also be fat particles localized to the skin or small particles formed due to acne vulgaris. The formation of such particles depends on other accompanying symptoms. If it is very hot summer, or in a hot environment without ventilation, it may be prickly heat. However, if this kind of small particles always exist at ordinary times, it may also be ordinary fat particles, which is caused by the proliferation of sebaceous glands.
