Why Do My Pores Look Bigger as I Get Older?

What a Pore Actually Is

Every pore on the face is the top of a hair follicle, usually a tiny, fine one. An oil (sebaceous) gland empties into it. The opening sits in the outer layers of skin and is held in shape by the collagen and elastic fibers around it, like the drawstring of a small bag. Pores don't open and close with heat or cold. What changes is how stretched, full or shadowed the opening looks.

The Three Main Causes

A widely cited dermatology review groups the causes of enlarged-looking pores into three.

Oil output

Oily skin tends to have more visible pores, especially on the nose, central forehead and chin. Oil output is driven largely by hormones — androgens in particular — which is why men usually produce more and why oil, and pore size with it, can shift across the menstrual cycle, rising around ovulation. A full, oily follicle has a wider, more visible opening.

Loss of support around the pore

The skin around each opening is held taut by collagen and elastic fibers. When that network weakens through intrinsic aging and, much more so, through years of sun exposure, the opening loses its tension and stretches. Studies link lower skin elasticity to larger pores. On the cheeks this shows up as pores that look elongated, oval or teardrop-shaped, sometimes lining up in rows. This is the cause that changes most with age. Our guide to what the collagen research actually says explains the collagen side.

Follicle size

Some people simply have larger follicles, and therefore larger pore openings, and that is mostly inherited. A large study of more than 2,500 women in five countries found that pore size and density varied far more with ethnicity than with age. Pores tend to appear around puberty, and in many groups their size changed relatively little after about 40.

Why Age Changes the Picture

If oil were the main driver, pores would shrink with age, because oil production generally declines after the 40s. They often don't, and the reason is support. As collagen and elastic fibers thin and fragment, particularly in sun-exposed skin, the follicle openings are held less firmly and the surrounding skin drapes slightly downward. That is why pores that were round and confined to the T-zone in your twenties can become larger and more oval across the cheeks in your forties and fifties.

Skin also renews more slowly with age. Dead cells linger on the surface, skin looks duller, and the shadow inside each pore stands out more. Our guide to why skin looks dull in winter covers that surface effect.

This also explains a common confusion. Tightening treatments aimed at sagging don't meaningfully change pore size. The loss of support that matters for pores is at the level of the skin around each opening, which is where resurfacing and collagen-remodeling treatments work. Our article on face tightening vs skin resurfacing explains the difference.

Other Things That Make Pores Look Bigger

• Clogging. A pore filled with oil and dead skin looks wider and darker. Sebaceous filaments — the grey or beige dots on the nose that refill within days of squeezing — are normal and not blackheads. Blackheads are true clogs whose tips have darkened in contact with air.
• Acne history. Repeated inflammation can damage the tissue around a follicle and leave it permanently wider. Some "large pores" are actually small, deep acne scars. See why adults get acne.
• Squeezing and picking. These stretch and inflame the opening, and repeated trauma can leave it larger.
• Dull or dehydrated skin. Pores stand out against a rough or dry surface and blend in against a smooth, hydrated one.
• Heavy or occlusive products. Some products settle into pores and emphasize them, and some can contribute to clogging.
• Lighting and magnification. Side light and magnifying mirrors exaggerate texture enormously. From conversational distance, most pores are far less visible than they look in a magnifying mirror.

Is It Really a Pore?

A few things are often mistaken for enlarged pores:

A Quick Self-Check

In daylight, without makeup:

1. 1Where are they? Round, oily pores on the nose, chin and central forehead point to oil. Larger, oval pores on the cheeks point to loss of support.
2. 2Is the skin shiny by midday? Then oil is a big factor.
3. 3Are they filled or dark? Then clogging is contributing.
4. 4Gently lift the cheek skin upward with a fingertip. If the cheek pores look noticeably smaller, stretching and support loss are part of the picture.
5. 5Do some have sharp edges and no visible opening? They may be acne scars.

What Helps Prevent Pores From Getting More Noticeable

• Daily broad-spectrum sunscreen. Sun damage is the biggest controllable driver of support loss around pores.
• A retinoid, where tolerated. Retinoids help skin renewal and collagen, and one large controlled trial found more improvement in pore appearance with a prescription retinoid than with placebo.
• Gentle, consistent oil and clog control for oily skin, without over-stripping.
• Hands off. Don't squeeze or pick.
• Keep the surface smooth and hydrated.

What Treatments Cannot Do

• No treatment permanently shrinks pores or makes skin "poreless." Pores are normal structures. Treatments improve how visible they are.
• Results from resurfacing and microneedling are gradual, build over a series, and fade without sun protection and maintenance.
• Tightening treatments aimed at sagging don't meaningfully change pore size.
• Products marketed as "pore-shrinking" mostly work by temporarily tightening, mattifying or filling the surface.
• Inherited follicle size and pores that have been wide for decades improve least.
• Resurfacing in deeper skin tones carries a higher risk of pigment change, so candidacy and settings matter.

Common Myths About Pores

Consultations at Youthful Magnolia in Fort Worth

At Youthful Magnolia in Fort Worth, a consultation about pores starts with working out which kind you have — oil-driven, congested, stretched by support loss, inherited, or something that isn't a pore at all — and with sun protection and skincare before any device is discussed. When resurfacing or microneedling fits, we explain what improvement looks like, how many sessions it takes, and what it won't change.

If you'd like a clear read on your pores and what, if anything, would help, book a consultation. You can also read about HALO, microneedling, and the best treatment for acne scars and large pores.
