You shouldn't pop a pimple, or it will form a scar and become infected. Keep it dry and keep it clean. Acne soap is good to use at least three times per day, like before school, after school and before bedtime. ANd never touch your face. Our hands pick up germs off of anything we touch. And touching your face transfers the germs and bacteria and general filth onto your face. So keep your face clean and dry and don't touch your face. I suspect makeup contributes to acne by clogging your pores too so you might want to lay off the facial makeup maybe just eye and lip makeup if you wear any.
