When you extract a blackhead, what is the stuff that comes out and why isn't it black?
That's interesting. How do blackheads form in the first place?
Blackheads form when excess oil, dead skin cells, and bacteria clog a hair follicle. When the pore is open, the clogged material is exposed to air and turns black, which gives blackheads their characteristic appearance.
