What causes zits and how can i stop zit pain and why do zits hurt im just curious?

Comedones: Zits (closed comedones) are inflamed blocked pores. They form when ducts on skin that make sebum (an oil your skin produces to protect it from drying out) become clogged. They can then become inflamed/infected causing pain. The best way to reduce this pain is to simply not touch them. You can prevent them by washing the area with water and soap daily. Benzoyl peroxide is also a good treatment.
