The Skin Nerd: Do the pores on your face really open and close?

Busting one of the biggest skin myths – whether pores really open.

Our pores, also known as our hair follicles, are simply openings in our skin, that allow hair (including vellus hairs, the fine, soft hair that covers the vast majority of us), oil and sweat to exit the skin.

I have more of a general skin question than a specific one about my own skin, but I’m really confused. 

My whole life I have purchased products that “open” my pores and used warm water to open them.
