5 Acne Myths You’ve Gotta Stop Believing, According to Dr. Pimple Popper

Truth: "You cannot permanently change your pore size," Dr. Lee said. But, "you can minimize the appearance of them. If you have something that's always plugging your pores, it can continually dilate [them] a little bit more, keeping them a little bit larger," Dr. Lee explained. Also, "as we get older our skin loses its elasticity, so your pores are going to naturally dilate."

And be wary of products and services that claim they can reduce the size of your pores. "There's so many companies out there or lasers that like to say they can shrink your pores, and that's simply not true," Dr. Lee said. "I think the best kind of measure is try to be proactive about it: try to help prevent them from dilating too much or enlarging too much."
