No, cold water doesn't actually "close" pores because pores don't have muscles to open and close, but splashing cold water can temporarily make them appear smaller by constricting blood vessels and tightening the skin, giving a refreshed look, though this effect is temporary and doesn't change pore size permanently. For better results, wash with lukewarm water to clean, then finish with a cold splash for that tightening sensation, focusing on consistent cleansing, exfoliation, and moisturizing for long-term pore appearance management.
Cold plunges and ice baths don't boost collagen or permanently tighten skin. However, the increased circulation may give a short-term radiance boost. Cold exposure offers mild, short-lived effects and can feel invigorating, but it's not a substitute for professional skin tightening or resurfacing treatments.
Pores can't open or close. They are simply small openings in the skin that are always in a static state. You can, however, reduce their appearance by keeping them free of congestion.
“There are no muscles around your pores, so ice will not do much,” Dr. Zeichner says.
Furthermore, the myth of cold water being able to shrink the size of pores has been proven false, since pore size is decided completely by genetics. However, cold -but not too cold- water does still have its benefits for the skin. Cold water causes blood vessels to contract, creating a tightened feeling.
What can treat large facial pores?
When we take a hot shower, our pores open, but cold showers can temporarily tighten them and help you retain the natural oils in your skin and hair. Those prone to dry skin or concerned about dry, brittle hair might consider rinsing off with cold water every so often.
More oil on your skin increases the risk of clogged pores. But lots of other things can lead to enlarged pores, including age, skin products, hair follicles and sun damage.
The sudden temperature drop can aggravate redness or irritation and doing it everyday is not a good at all. It can compromise your skin's natural barrier making it dry and sensitive.
Ice can temporarily tighten the appearance of skin by constricting blood vessels and reducing surface-level swelling. This creates a smoother, more toned look, especially around areas prone to puffiness like the eyes or jawline.
The 4-2-4 rule is a Korean-inspired deep cleansing method: massage an oil cleanser for 4 minutes to break down makeup/SPF, follow with a water-based cleanser for 2 minutes to remove residue, then rinse with 2 minutes of warm water and 2 minutes of cold water to open and close pores, leaving skin deeply clean but can be irritating for sensitive types, so it's best for deep cleaning or heavy makeup days, not daily.
Dermatologists recommend keeping your showers between 5 and 10 minutes. This time period gives you enough time to properly clean your body without overdoing it. If you have certain skin conditions, staying in the shower too long could have negative effects.
Open pores may be a common skincare concern, but they are not harmful. While you cannot close them permanently, you can control and minimize their appearance with the right mix of home remedies, skincare products, lifestyle changes, and professional treatments.
If you wake up with a puffy face, fill your sink with cold water or take a cold shower. The water will constrict blood vessels to cut down on redness, hydrate your skin, and debloat your face overall. You can also include an anti-inflammatory soap, oil, or supplement in your sink for added skin benefits.
Sun exposure
Researchers estimate that exposure to sunlight's UVA and UVB rays counts for 90% of the symptoms of skin aging. Over time, this damage adds up, resulting in wrinkles, age spots, and visible redness.
After 30 days of cold showers, people often report increased energy, better mood, improved mental resilience, and sharper focus, alongside potential physical benefits like better circulation, skin/hair health, reduced inflammation, and muscle recovery, largely due to the body adapting to the stress and the activation of systems that boost alertness and metabolism, though individual results vary.
“Cold water helps give your face vitality and more color. It also enhances the brightness of your skin by getting the circulation going and literally waking up your skin,” board-certified dermatologist Sheel Desai Solomon, MD, previously told Well+Good.
Use a gentle, non-abrasive cleanser that does not contain alcohol. Wet your face with lukewarm water and use your fingertips to apply cleanser. Resist the temptation to scrub your skin because scrubbing irritates the skin. Rinse with lukewarm water and pat dry with a soft towel.
The cooling effect of ice stimulates circulation and helps to lighten dark spots by encouraging skin regeneration. Regular use of ice can also reduce skin discoloration caused by acne scars or sun damage.
The best way to minimize pores involves salicylic acid. A type of BHA, salicylic acid penetrates deep into the pores to dissolve oil and debris. With consistent use over time, it leaves skin smoother and makes pores appear smaller.
Carbohydrates like sugar and fats are quickly absorbed by the bloodstream, which can lead to a spike in blood sugar levels and an overproduction of sebum, resulting in oily pores. Too many animal-based foods like meat and dairy might boost our bodies' hormone production, also stimulating our skin's oil glands.
Results: The enlarged pores of the nose and forehead were more prominent than in the cheeks. Pore counts were increased with age, and the increment was significant between the 30's and 40's.
So yes, cold therapy can make your skin look momentarily firmer and calmer, but it's a temporary physiological response, not a structural skin change. Cold plunges and ice baths don't boost collagen or permanently tighten skin. However, the increased circulation may give a short-term radiance boost.
When you apply ice to your face, the cold temperature causes your blood vessels to constrict, giving your skin a temporarily tighter, smoother look. Your pores seem smaller—but only until your skin warms up again. Think of it like leaving an ice cube out: it melts.
The main difference is that a cleanser starts the cleaning process, opening pores and invigorating top-layer skin cells. Toner can then be applied to tighten your pores and remove any dead skin cells.
