“Pores are an precise bodily construction, a gap of the pores and skin. So, what surrounds that opening? Pores and skin—and if you get deeper into the pores and skin, there’s collagen. So, there are bundles of collagen that encompass that pore. It’s squeezing across the pore with the collagen,” he explains. “As these bundles of collagen begin to diminish, particularly with age, that structural assist that’s holding the pore tight will loosen. As you lose that collagen and as you age, your pore may also begin to dilate since you’ve misplaced that collagen.”
