Ever wondered if your pores actually open and close like tiny doors on your face? You're not alone. The pores can open and close myth is one of skincare's most persistent misconceptions, passed down through generations of beauty advice. From your mum telling you to splash cold water to "close" your pores after cleansing, to countless skincare routines promising to "open" them for better product absorption, this myth has shaped how we think about our skin. But here's the real talk: pores don't have muscles, hinges, or any mechanism that allows them to open and close. What you're seeing when pores appear larger or smaller is something entirely different—and understanding this can revolutionise your skincare routine. At Smytten, we believe in cutting through the noise to bring you science-backed skincare facts that actually help your skin thrive. Let's dive into what's really happening with your pores and why this myth has stuck around for so long.
TL;DR
Pores cannot physically open and close as they lack muscles or any opening/closing mechanism
What appears as "opening" is actually pore dilation caused by heat, oil buildup, or inflammation
Temperature changes, cleansing, and skincare products can make pores appear larger or smaller temporarily
Effective pore treatments focus on keeping them clear and maintaining skin elasticity, not "closing" them
Understanding pore science helps you choose better skincare products and realistic treatment expectations
Let's start with the science that debunks this persistent myth once and for all. Pores are simply openings in your skin where hair follicles emerge, connected to sebaceous glands that produce natural oils. Unlike your eyes or mouth, pores don't have muscles surrounding them that could contract or relax to change their size.
When people ask "do pores open and close," what they're really observing is the appearance of pore size changing under different conditions. Think of it like this: a pore is more like a funnel than a door. The opening can appear wider or narrower based on what's inside it and how the surrounding skin behaves, but the actual structure doesn't open and close.
So why does this myth persist in skincare culture? Partly because the visual changes are real—pores do look different after a hot shower versus a cold splash of water. The confusion comes from misinterpreting these temporary visual changes as actual opening and closing. Marketing hasn't helped either, with countless products promising to "open pores for deep cleansing" or "close pores for a smooth finish."
Understanding what actually makes pores appear larger helps explain why the opening and closing myth feels so believable. Several factors can make your pores look more prominent, creating the illusion that they've "opened up."
When you expose your skin to heat—whether from a hot shower, steam, or warm compress—blood vessels dilate and skin becomes more pliable. This can make pores appear larger temporarily, but they're not actually opening. The heat simply makes the surrounding skin softer and more flexible.
When pores get clogged with sebum, dead skin cells, or makeup residue, they stretch to accommodate the buildup. This stretching makes them appear larger and more noticeable. It's like stuffing a sock—the opening gets wider to fit more content inside.
Age, sun damage, and genetics all affect skin elasticity. As collagen production decreases and skin loses firmness, pores can appear larger because the surrounding skin doesn't bounce back as effectively. This is why pores often become more noticeable as we age.

Harsh lighting, certain angles, and even humidity levels can make pores appear more or less prominent. This is why your pores might look fine in your bathroom mirror but seem huge in your car's visor mirror—it's all about the lighting and angle.
Now that we understand what's really happening with pore appearance, let's tackle some of the most persistent myths about pores that continue to influence skincare routines worldwide.
This is probably the most widespread pore myth. While hot water can make pores appear larger due to increased blood flow and skin pliability, it's not actually opening them. Similarly, cold water might make pores look smaller by constricting blood vessels, but it's not closing them either.
Pore size is largely determined by genetics. While you can make them appear smaller through proper skincare and professional treatments, you can't permanently change their actual size. What you can do is keep them clear and maintain skin elasticity to minimise their appearance.
Some products claim to seal pores completely, but this would actually be problematic for skin health. Pores need to function properly to release sebum and allow hair growth. The goal should be keeping them clear, not sealing them.
While steaming can soften skin and make it more receptive to products, it's not because pores are "opening." The heat increases blood circulation and makes the skin more pliable, which can enhance product penetration through the skin barrier.
To understand how to properly care for your pores, it helps to know how they function normally and what happens when things go wrong.
Healthy pores work as part of your skin's natural oil production system. Sebaceous glands produce sebum, which travels up through the hair follicle and out through the pore opening to moisturise and protect your skin. This is a completely normal and necessary process.

Problems arise when this natural flow gets disrupted. Dead skin cells, excess oil, bacteria, or external debris can create blockages. When a pore gets partially blocked, you might see a blackhead (oxidised oil and debris). Complete blockages can lead to whiteheads or, if bacteria gets involved, inflamed acne.
Several factors can make pores more prone to clogging: hormonal changes that increase oil production, using heavy or comedogenic products, inadequate cleansing, and even genetics. Understanding your personal risk factors helps you choose appropriate skincare strategies.
While you can't permanently shrink pores, you can definitely improve their appearance and function. Here are science-backed approaches that actually work, focusing on keeping pores clear and maintaining skin health.
Retinoids are gold standard for pore appearance. They increase cell turnover, preventing dead skin buildup and helping maintain skin elasticity. Niacinamide helps regulate oil production and can reduce the appearance of enlarged pores. Salicylic acid penetrates into pores to clear out debris and prevent clogging.
Chemical peels can help with surface texture and mild pore concerns. Microneedling stimulates collagen production, which can improve skin firmness around pores. Laser treatments can address more significant concerns, but they require professional consultation and realistic expectations.
Consistent gentle cleansing removes daily buildup without over-stripping skin. Regular exfoliation (chemical preferred over physical) helps prevent dead skin accumulation. Proper moisturising maintains skin barrier function, which actually helps with overall pore appearance.
Neither hot nor cold water can actually open or close pores. Hot water may make pores appear larger temporarily due to increased blood flow and skin pliability, while cold water might make them look smaller by constricting blood vessels. These are temporary visual changes, not actual opening or closing.

You cannot permanently close pores, nor would you want to—they serve important functions for skin health. Instead, focus on keeping them clear through proper cleansing, using appropriate skincare ingredients like niacinamide or retinoids, and maintaining good overall skin health. This will minimise their appearance naturally.
Pores don't open and close with heat, but heat can make them appear larger temporarily. When skin is exposed to heat, blood vessels dilate and skin becomes more pliable, which can make pores look more prominent. This is a temporary effect that reverses as skin returns to normal temperature.
The concept of pores being "open" is misleading since they don't actually open and close. What matters is that your pores are functioning properly—allowing natural oil flow without becoming clogged. Visible pores are completely normal and healthy; the goal should be keeping them clear rather than trying to make them invisible.
Absolutely! Smytten offers trial packs of various pore-focused skincare products, allowing you to test ingredients like niacinamide, retinoids, and salicylic acid before committing to full-size purchases. This is particularly helpful since pore treatments often require consistent use to show results.
Several factors can make pores appear larger suddenly: hormonal changes increasing oil production, using new products that don't suit your skin, inadequate cleansing leading to buildup, dehydration making skin less plump, or even changes in lighting or environment. Identifying the trigger helps address the issue effectively.
The most important thing to remember is that pores cannot physically open and close—this is simply a persistent myth that has shaped skincare advice for generations. What you're seeing when pores appear larger or smaller are temporary changes in appearance due to factors like heat, oil buildup, skin elasticity, and lighting conditions.
Effective pore care focuses on keeping them clear and maintaining overall skin health rather than trying to "close" them. Ingredients like niacinamide, retinoids, and salicylic acid can help improve pore appearance by addressing the underlying factors that make them more noticeable. Professional treatments can also be beneficial, but they work by improving skin texture and firmness, not by permanently shrinking pores.
Remember that visible pores are completely normal and healthy. The goal shouldn't be to eliminate them entirely but to keep them functioning properly and minimise their appearance through good skincare practices. Understanding the science behind pore function helps you make better product choices and set realistic expectations for your skincare routine.
