Blackheads and rough skin: dissolve them, don't squeeze them

Run a finger across your forehead or chin. If it feels like sandpaper, or you can see tiny dark dots on the nose and small skin-coloured bumps that never quite become pimples, this guide is for you.

All three come from the same thing: build-up. Skin sheds a layer of dead cells every few weeks, and in heat and humidity, with sunscreen and sweat on top, those cells mix with oil and don't leave cleanly. Inside a pore they make a plug. On the surface they make a rough film.

Blackheads, whiteheads and texture

A blackhead is a plug of oil and dead skin in an open pore. The top darkens where air reaches it. It is not dirt, so washing harder doesn't shift it.

A closed comedone, sometimes called a whitehead, is the same plug under a thin layer of skin. These are the small, flesh-coloured bumps across the forehead and chin that make skin feel bumpy without looking red.

Rough texture is dead skin sitting on the surface. Makeup clings to it, and skin looks dull because light scatters instead of reflecting.

Not every grey dot on the nose is a blackhead. Most noses have sebaceous filaments, a normal lining of oil in every pore that refills within weeks. They respond to the same routine, but they never disappear for good. If your real question is how big your pores look, our large pores guide is the better start.

Oil cleansing: the first step at night

Oil dissolves oil. A cleansing oil massaged over dry skin softens hardened plugs so they can lift out with the rinse. Anua Heartleaf Pore Control Cleansing Oil also contains a little salicylic acid. Use dry hands on a dry face, spend a full minute on the nose, chin and forehead, add a splash of water until it turns milky, then rinse.

Follow with a wash that keeps working in the pores: CeraVe SA Smoothing Cleanser or COSRX Salicylic Acid Daily Gentle Cleanser. In the morning, something milder is enough, like Beauty of Joseon Green Plum Refreshing Cleanser or Anua Heartleaf Quercetinol Pore Deep Cleansing Foam.

BHA for inside the pore, AHA for the surface

The two acids do different jobs, which is why bumpy skin with blackheads often needs both.

• BHA (salicylic acid) dissolves in oil, so it gets inside the pore and loosens the plug. It is the main treatment for blackheads and closed comedones. COSRX BHA Blackhead Power Liquid, two or three nights a week.
• AHA (glycolic or lactic acid) dissolves in water and works on the surface, loosening the dead cells that make skin rough. The Ordinary Glycolic Acid 7% Exfoliating Toner on one or two other nights. Pads like Medicube Zero Pore Pad 2.0 or Anua Heartleaf 77 Clear Pad are an easy alternative.

Put them on different nights. Together, or with retinol, they strip the skin barrier, and a stinging, peeling face is not smoother. If you'd rather use one gentle product every day, COSRX AHA/BHA Clarifying Treatment Toner or SOME BY MI AHA BHA PHA 30 Days Miracle Toner carry low doses of both.

The Ordinary AHA 30% + BHA 2% Peeling Solution is a strong ten-minute peel. It is for people already used to acids, at most once a week, never on the same night as anything else that exfoliates.

Clay, once a week

Beauty of Joseon Red Bean Pore Mask uses kaolin clay to draw oil out of congested pores. Apply it to the T-zone on a night with no acid, and rinse before it cracks. It is a helper, not a treatment on its own.

The first few weeks

When you start a BHA, some people get a short run of small breakouts where they already had clogs. That's called purging: the plugs come up faster than they would have. It should settle within four to six weeks and stay in your usual spots. Breakouts in new places, burning or peeling mean the product is too strong or too frequent, so cut back.

Acids also make skin more sensitive to the sun, so sunscreen every morning is part of this routine. A light gel moisturiser at night keeps the skin barrier comfortable while you exfoliate.

What to skip

• Squeezing with nails or a metal extractor. It pushes some of the plug deeper and leaves red marks that last weeks.
• Pore strips and parlour "deep cleans". They tear the top off and leave the rest.
• Walnut, apricot or sugar scrubs. Hard grains scratch, and scratched skin feels rougher.
• Toothpaste, baking soda and lemon. They dry the surface and irritate it without touching what is inside the pore.

If your bumps are red, sore or full of pus, that's acne rather than simple congestion, and our acne routine fits better. Tiny bumps on the forehead that itch and spread can be fungal, and a dermatologist can tell you.

We sell the products named here, so weigh our picks with that in mind.
