Large pores and blackheads — why do they keep coming back?

The closer you lean toward the mirror hoping for smoother skin, the more the wide pores and dark blackheads are all you notice. Squeeze and strip harder and they seem like they should vanish — usually they do the opposite.

Pores look large and blackheads keep coming back because there's a lot of sebum, that sebum and dead skin widen the pore, and the trapped sebum oxidizes in air to look dark. Among several factors, sebum output correlates most with pore size, and as skin loses firmness with age, pores look more stretched (Roh et al., 2006). A blackhead's dark color isn't dirt; it's oxidized sebum and keratin plugging the pore (Saint-Léger et al., 1986). So rather than squeezing or scrubbing them off, it helps to manage sebum and dead skin gently and protect the barrier, easing the sebum rebound.

Why do pores look large?

Three things usually overlap. First, sebum: among several factors, sebum output correlated most with pore size (Roh et al., 2006). Second, dead skin: when keratin and sebum clump and plug the pore opening, that spot stands out more. Third, firmness: as age and accumulated UV reduce collagen, the support around pores weakens and they look more stretched. You can't erase or permanently close pores, but managing these three makes them stand out less.

Are blackheads just dirt?

Many people think a blackhead is dirt. It isn't. A blackhead is an open comedone — sebum and keratin plugging a pore — and its contents darken as they oxidize in air. In fact, the lipids inside comedones were mostly oxidized squalene (Saint-Léger et al., 1986). So the dark isn't grime; it's oxidized sebum. That's why scrubbing hard won't remove it, and oil cleansing won't lift it all in one go, while forcing it out damages the pore wall, leaving marks or larger pores.

Why does squeezing and stripping make it worse?

Here's what many miss. Squeezing blackheads, ripping with pore strips, scrubbing, and stripping oil with harsh cleansers looks clean for a moment. But when that irritation breaks the barrier, skin makes more sebum to compensate for the dryness. The surface is stripped while underneath gets oilier, and pores widen from the irritation. For why sebum actually rises, see the real reason skin makes so much oil; for how clogged pores and the barrier connect, see why a broken barrier leads to breakouts.

So how do you manage large pores and blackheads?

First, cleanse gently: with lukewarm water, lift only the oil, softly. Next, don't scrub dead skin off — dissolve it. A gentle ingredient like BHA (salicylic acid) at low strength, now and then, dissolves the sebum and keratin in pores and reduces plugging. Then refill the barrier with moisture to ease the sebum rebound. Finally, block UV every day to slow the loss of firmness. Don't squeeze blackheads; instead of pore strips, empty them slowly with gentle exfoliation.

Should you strip more, or take something away?

Read pores and blackheads as proof of being dirty, and you miss the point. They're the natural buildup and oxidation of sebum and dead skin. The harder you squeeze and strip, the wider pores get and the more sebum returns. What the skin needs isn't something stronger added on top; it's the constant irritation taken away, so the barrier can support itself again. Ease the friction, empty pores gently, and protect the barrier, and pores stand out less while blackheads slowly fade. We don't change your skin. We wake it up.

Where could you start today?

Before reaching for a new product, you might look at these first.

• Don't squeeze blackheads with fingers or tools; instead of pore strips and scrubs, use a gentle exfoliant like BHA (salicylic acid) at low strength, now and then.
• After cleansing, refill the barrier with moisture. A dry barrier makes skin produce more sebum, so pores stand out more.
• Block UV by day. Keeping firmness means pores look less stretched.
