Blame a dull-looking complexion on poor circulation, which reduces how much oxygen and nutrients reach your skin; wrinkles and sagging skin on diminished cell turnover and decreased collagen and elastin synthesis; and a drop in melanin production for shining a spotlight on various imperfections like under-eye circles and blemishes.

How to treat it: Determined by genetics, intrinsic aging leaves us with little control in halting it. Thankfully, though, you’ll find an array of products that target its symptoms. For instance, an age inhibitor complex addresses the main components of aging- the breakdown in collagen and elastin- by preserving elasticity and preventing collagen loss. Also try Murad Intensive Wrinkle Reducer to firm and hydrate the skin and reduce fine lines and wrinkles.
