Pores. Everyone has them, but not everyone loves them. You’ve probably seen products that claim to "shrink" or "erase" pores — but is that really possible?
Let’s get into the facts.
What Are Pores?
Pores are small openings on the surface of the skin that allow the release of sebum (natural oil) and sweat. They play an essential role in maintaining skin health by supporting lubrication, barrier function, and temperature regulation.
There are two main types of pores:
Sebaceous pores are connected to oil glands and release sebum to help protect and condition the skin.
Sweat pores are linked to sweat glands and help regulate body temperature.
The pores most people are concerned about visually are sebaceous pores, particularly across the nose, forehead, and chin where oil activity is naturally higher.
Pores are not defects — they are structural openings that allow the skin to function normally.
Why they exist, why they change, and what skincare can (and can’t) do
Pores are often treated as a problem to fix — something to shrink, erase, or hide.
But pores aren’t a flaw in the skin. They’re a functional part of how skin works.
Rather than trying to eliminate them, the goal of good skincare is to support the skin around the pore — keeping it clear, resilient, and well supported so pores appear less noticeable over time.
What Influences How Pores Look?
Pore size itself is largely determined by genetics, but several factors influence how visible pores appear.
Genetics
Your baseline pore size is inherited. If larger pores run in your family, you’re more likely to see them as well.
Age
As collagen and elastin gradually decline with age, the skin loses some of its firmness and support. This loss of structural integrity can make pores appear more prominent.
Sebum Production
Excess oil can stretch the pore walls, making pores appear larger. Hormonal shifts, stress, and over-stripping the skin can all increase oil production.
Sun Exposure
Chronic UV exposure breaks down collagen and elastin in the skin. Over time, this weakens the surrounding tissue and allows pores to widen.
Congestion and Skincare Habits
When dead skin cells and oil build up inside the pore, they can exaggerate its appearance. Using comedogenic products or neglecting sun protection can worsen this effect.
Can Pores Be Shrunk?
Pore size is anatomically fixed.
Pores don’t have muscles, so they cannot open or close — and they cannot be permanently reduced in size.
What can change is how visible they appear.
When pores are kept clear, the surrounding skin is well hydrated, and collagen support is maintained, pores naturally look more refined.
The aim is not elimination — it’s support and refinement.
How Skincare Can Improve the Appearance of Pores
Consistent, barrier-respecting skincare plays a significant role in how pores look over time.
Gentle Cleansing
Using a mild, pH-balanced cleanser removes excess oil and debris without stripping the skin. Over-cleansing can trigger increased oil production, which often worsens pore appearance.
Targeted Exfoliation
Salicylic acid (BHA) is oil-soluble, meaning it can move into the pore lining and help dissolve excess sebum and dead skin cells. Used consistently and appropriately, it helps keep pores clear and reduce congestion.
Collagen Support
Ingredients such as retinoids support cell turnover and collagen production, helping strengthen the skin around pores and improve overall texture.
Daily Sun Protection
UV exposure accelerates collagen breakdown, which directly affects pore visibility. Daily use of a non-comedogenic SPF is one of the most effective long-term strategies for maintaining pore structure.
Hydration and Barrier Support
Well-hydrated skin appears smoother and more elastic. Lightweight moisturisers, humectants, and barrier-supporting ingredients help maintain skin resilience without clogging pores.
Common Pore Myths
Hot water opens pores and cold water closes them.
Pores do not open or close. Temperature changes may temporarily affect the skin’s surface, but they do not alter pore structure.
You can erase pores with the right product.
No topical product can eliminate pores. Claims to “shrink” or “erase” pores are marketing language, not anatomy.
Oily skin is dirty skin.
Sebum is essential for skin health. Over-cleansing or harsh treatments often increase oil production rather than reduce it.
The Takeaway
Pores are a natural and necessary part of healthy skin.
While their size cannot be changed, their appearance can be softened by supporting the skin around them — keeping pores clear, maintaining collagen, protecting from UV damage, and respecting the skin barrier.
Healthy skin isn’t about correction or perfection.
It’s about balance, structure, and long-term support — allowing the skin to function as it’s designed to.
Pro Tip: Celebrate your pores. They’re proof your skin is alive, functional, and beautifully human. Focus on care, not correction.
