Pores are tiny holes present on the skin surface. The pores bring out the sweat and oil secreted by the sweat glands and the sebaceous glands respectively. While the sweat glands open by separate pores, the sebaceous glands open through pores located along the hair follicles. An SVYM initiative

The size of the pores is about 30-50 microns (1 micron = 0.000 001 metre). These pores are closed at normal conditions and open when the glands are actively secreting. The secretion of these glands is influenced by the body temperature and hormones. Hence there is no chance of water seepage through the pores. Vijnana Vahini Files
