Blackheads and whiteheads—known as comedones—form when the pore becomes clogged with oil, dead skin cells, and bacteria. This is the first stage of acne.

1) Excess Oil Production
Oily skin produces more sebum. When oil mixes with dead skin inside the pore, it creates a plug that blocks natural flow.

2) Dead Skin Buildup
Acne-prone skin sheds cells faster than normal. These cells accumulate and stick together, worsening the blockage.

3) Whiteheads (Closed Comedones)
When the pore is sealed at the surface, oil and debris remain trapped beneath the skin, forming a small, raised bump.

4) Blackheads (Open Comedones)
If the pore stays open, the trapped material oxidizes when exposed to air—turning dark.
It’s oxidation, not dirt.
