Pores contribute to our skin’s natural hydration process, moisturizing our skin and keeping it supple. But as our skin loses elasticity as we grow older, skin can stretch and sag, making pores appear larger. Age and sun damage also thickens skin, which causes a tiny gathering of cells around the pores, making them look bigger. Extensive sun exposure can also impact collagen, elastin, and water in your skin, causing the tissues to shrink and pull at the edge of pores.
