Whiteheads
Whiteheads are small white or flesh-coloured bumps that appear where oil glands are active, often alongside blackheads. They are closed comedones: the same plug of sebum and dead cells as a blackhead, but trapped under a thin layer of skin that keeps the pore sealed. Because the contents never meet the air, they stay pale rather than darkening.
A plug sealed from the air
A whitehead forms when the plug develops but the pore opening stays covered by a fine layer of skin. Sealed away from oxygen, the trapped sebum and cells keep their pale colour instead of oxidizing dark like a blackhead. It is worth distinguishing whiteheads from milia, which are tiny keratin cysts unrelated to the pore and the oil gland, and which call for a different approach.
How do whiteheads form?
Whiteheads, like blackheads, sit at the early non-inflammatory stage of the cascade: a plug has formed but inflammation has not yet taken hold. The difference is simply that the pore stays closed. The factors below explain why the plug forms, why it stays sealed and why pressing on a whitehead risks tipping it into something worse.
Excess oil production
Whiteheads begin with the same surplus of sebum as any comedone. When androgen-sensitive oil glands produce more than the follicle can drain, the excess combines with dead cells to form a plug. The more active the glands in a given area, the more readily these plugs appear, which is why whiteheads favour the oilier central face and other gland-dense zones.
Build-up of dead cells
When the cells lining the channel shed too slowly or clump together, they combine with sebum to block the follicle. In a whitehead, this plug sits beneath an intact surface layer that keeps the pore closed. The trapped material has nowhere to drain, which is why supporting even, gentle cell turnover helps prevent these sealed plugs from forming.
Occlusive Products
Heavy or occlusive products can seal the pore surface and help keep the plug enclosed. Rich creams, comedogenic cosmetics and makeup left on overnight all add to the load and the occlusion. Because a whitehead is already a closed lesion, anything that further covers the follicle keeps the trapped contents in place and the bump visible for longer.
The temptation to squeeze
A whitehead looks ready to press, but squeezing can rupture the sealed follicle wall and release its contents into the surrounding skin. That turns a quiet closed comedone into active inflammation, with the redness, swelling and risk of marks that follow. The closed plug is relatively harmless until it is forced open the wrong way.
