Vitamins, applied topically, are key. Try a nutrient- and anti-ager-packed cleanser to remove the bad (dirt, makeup) and leave behind the good (like niacinamide, a component of B3 that builds strong new skin cells). Follow it with a vitamin C–enhanced sunscreen to scrounge up sag-inducing free radicals. Used nightly, a
product with peptides increases collagen and repairs skin.
