Enlarged Pores
You can’t close pores — but you can genuinely improve how they look.
Enlarged pores are one of the most common skin concerns and one of the most misunderstood. Pore appearance is influenced by genetics, oil (sebum) production, age-related collagen loss and sun damage — and, importantly, pores don’t have muscles, so they don’t ‘open’ and ‘close.’
That means the honest goal isn’t to shrink pores permanently — it’s to make them look smaller by addressing what makes them prominent: excess oil, debris, and lax skin around them. With the right plan, that appearance can improve meaningfully; with the wrong expectations, no product will ever satisfy.
Myth, Busted
Pores have no muscles — they don’t open or close, no matter what the internet says.
At A Glance
What Influences Pores — and What Helps
Pore appearance has a few real drivers. Treatments that address those drivers work; the popular ‘pore-closing’ myths don’t.
Enlarged pores, simplified
The goal is appearance — pores can’t be permanently closed
What influences pore appearance
- Genetics
- Oil (sebum) production
- Age-related collagen loss
- Sun damage
- Clogging with debris / dead skin
What actually helps
- Retinoids (regulate turnover & oil)
- Niacinamide
- Gentle, consistent exfoliation
- Laser / collagen-stimulating treatments
- Daily sun protection
Educational summary only. Pores have no muscle and cannot be ‘opened’ or ‘closed’; steam and cold water do not change pore size.
The DriversWhy Pores Look Larger
A few real factors make pores more prominent:
Genetics
Pore size is largely inherited — the baseline you start from.
Oil Production
More sebum stretches and fills pores, making them look larger.
Collagen Loss
As supporting collagen declines with age and sun, pores lose their ‘frame’ and appear bigger.
Sun Damage
Photoaging thickens and loosens skin around pores, accentuating them.
Clogging
Debris and dead skin within pores make them more visible.
The Myths
Steam, cold water and ‘pore-closing’ toners don’t change pore size — pores have no muscle.
The OptionsWhat Genuinely Improves Pores
Effective treatment targets the real drivers — oil, debris and lax surrounding skin — rather than chasing the myth of closing pores.
Skincare that works
Retinoids regulate cell turnover and oil, niacinamide helps, and consistent gentle exfoliation keeps pores clear — all part of a medical skincare plan.
Collagen-stimulating treatments
Laser resurfacing and microneedling build collagen around pores, tightening their ‘frame’ so they look smaller and refining overall texture.
Protect the result
Since sun damage worsens pore appearance, daily protection is part of keeping improvements.

How We DecideEvidence-Based Practice
Aesthetic medicine changes rapidly, and novelty alone is not evidence. At Onassis Skin Health, treatment and skincare protocols are developed with reference to peer-reviewed medical literature and respected clinical guidance — then interpreted for the individual in front of us.
Research does not replace clinical judgment. It informs it.
Published evidence is read in the context of your anatomy, skin type, medical history, risk profile, lifestyle and desired outcome. Product and technique selection, dosing or placement, and pre- and post-care all follow from that combination of evidence and individualized assessment — not from what is simply popular or available for purchase.
When AppropriateA Realistic Plan
Pore appearance improves with a plan that targets its real drivers over time:
+ Medical Skincare
A prescriptive regimen — including ZO Skin Health when appropriate — to treat the concern directly and support any in-office treatment.
+ In-Office Treatment
Laser or other procedures when they genuinely add value, matched to your skin and goals.
+ Photoprotection
Daily broad-spectrum sunscreen to protect results and prevent the concern from worsening.
Combinations are recommended only when each element contributes meaningfully to your goals. Sometimes the right plan is a single, well-chosen treatment — and sometimes it is choosing not to treat at all.
What to ExpectHonest Expectations
The goal is a visible, satisfying improvement in how pores look — not permanent closure, which isn’t physiologically possible. With consistent skincare and, where appropriate, collagen-stimulating treatment, most patients see real refinement. We’ll be straightforward about what’s achievable for your skin.
QuestionsFrequently Asked
Can I permanently shrink my pores?
No — pores can’t be permanently closed, but their appearance can be genuinely improved by treating oil, debris and surrounding collagen.
Do steam or cold water open and close pores?
No — pores have no muscle. These don’t change pore size; the idea is a myth.
What actually helps most?
Retinoids and consistent skincare, plus collagen-stimulating treatments like laser or microneedling where appropriate.
Does sun damage make pores worse?
Yes — it loosens the collagen around pores, so daily sun protection helps.
How long until I see a difference?
Skincare takes weeks to months; in-office treatments add refinement over a series.
