While some people may just have larger pores naturally (pore size is genetic, and they don’t actually shrink), orange peel skin is often a result of collagen decline. “It’s a sign of sun damage and aging. Basically, as collagen and elastin are compromised, the pores are not held closed, leaving them larger and more visible,” says Morgan Rabach, M.D., board-certified dermatologist and co-founder of LM Medical NYC.
