A silver-haired woman with still-taut cheekbones smiles from the ad. A pitch for magic potions aimed at women with crow’s feet and creases. A woman like me, experienced in flutters of self-doubt and twinges of loss. Vulnerable to the seductive pull of junk science and sly text—serums with proven clinical strength, the latest in anti-wrinkle technology. Sweet-smelling fruit extracts to moisturize, rejuvenate, illuminate. Who doesn’t want to glow with renewed vitality?
