As you may already know, your skin contains thousands of tiny little holes called pores. All pores have something inside them called sebaceous glands which produce an oil called sebum. Under normal circumstances, sebum exits the pore and doesn’t cause any problems. In some unfortunate circumstances, the pore becomes blocked and infected, and the sebum gets stuck inside the pore, causing a pimple. The pimple usually starts as a blackhead or whitehead, sometimes too small to see with your eyes, and if the wall of the pore breaks, can form an inflamed pimple, also called a papule and pustule.
