Here’s what really happens

Here’s what really happens:

Ice can make pores appear smaller, but it doesn’t actually shrink them in a lasting way. Here's how:

Cold causes vasoconstriction: When you apply ice to the skin, it constricts blood vessels and tightens the surrounding tissue. This reduces inflammation and puffiness, which can temporarily make pores look smaller.
Less oil and swelling = smoother look: By calming redness and reducing surface oil, ice can help your skin look smoother and more refined—again, temporarily.

But here's what ice can't do:

Change your pore size permanently: Pore size is mostly determined by genetics, oil production, and aging (loss of collagen). No topical product or ice cube can truly shrink them long-term.

So, is it worth doing?

Yes, if you're looking for a quick refresh or de-puffing effect before makeup or in the morning, icing can be a useful trick. Just avoid overdoing it—it can irritate or damage capillaries if held too long or applied too harshly.
