Acne is basically a disorder related to the oil glands present under the skin. The pores of the skin are attached to the oil gland cells from inside, due to which sebum oil is produced in the skin pores. Sebum helps to bring bad cells out of the follicles, with which new cells are formed. But many times this sebum oil starts to be produced in large quantity due to unbalanced hormone, which causes the pores to close and pimples or rash. The growth of bacteria in the sebum also causes the pores to stop, which makes acne problems common.
