Blackheads are one of the most common forms of acne. Although people who have oily skin are more vulnerable to blackheads, anyone can get them.
They form when pores become clogged with a combination of dead skin cells and excess oil (sebum) from your sebaceous glands.
Unlike whiteheads, which create closed pores, blackheads have open surfaces, which creates an oxidation that’s dark in color.
It may be tempting to try to pinch or push the black plug out, but this can cause unnecessary scarring and other damage to your skin.
