Blackheads
Blackheads are small dark dots that appear most often on the nose, chin and forehead, where oil glands are densest. They are open comedones: plugs of sebum and dead cells sitting in a pore whose opening stays wide. Despite their colour, they are not dirt, which is why scrubbing harder never clears them.
Why they turn dark
A blackhead forms when sebum and dead cells clump into a plug inside the follicle. Because the pore stays open, the top of the plug meets the air and oxidizes, darkening exactly like a slice of apple left out on the counter. The black colour comes from this oxidation and the skin's own pigment, not from grime, so the answer is to keep the channel clear rather than to scrub.
How do blackheads form?
Blackheads sit at the early, non-inflammatory stage of the acne cascade: a plug has formed, but bacteria and inflammation have not yet taken over. They reflect how much oil the glands make and how well the pore channel sheds its cells. The factors below explain why blackheads form, why they darken and why squeezing tends to make things worse.
Excess oil production
Blackheads begin with sebum. When the oil gland, prompted by androgen hormones present in everyone, makes more than the follicle can drain, the surplus mixes with dead cells and starts to form a plug. Areas with the largest, busiest glands, the nose and central face, are therefore where blackheads cluster most. More oil simply means more raw material for the plug.
Cells that shed too slowly
The cells lining the pore channel are meant to shed and clear continuously. When they renew too quickly or stick together instead of detaching cleanly, they pile up and combine with sebum into a plug. This sticky build-up is what physically blocks the channel. It is also why approaches that help the skin shed evenly target blackheads at their root.
Oxidation, not dirt
What makes a blackhead black is air, not grime. In an open pore, the surface of the plug oxidizes on contact with oxygen and darkens, the same reaction that browns a cut apple. Understanding this matters: because the colour is oxidation and pigment rather than trapped dirt, harsh scrubbing cannot wash it away and only irritates the skin.
Comedogenic products
Heavy or occlusive cosmetics, oils and sunscreens can add to the plug by sealing the pore opening and supplying extra material. Products that sit on the surface without absorbing are most likely to contribute. Makeup left on overnight compounds the effect. Choosing non-comedogenic formulas reduces this external load on follicles that are already prone to clogging.
