Meghan Markle's latest Harper's Bazaar cover reminded Us of one thing: she has ageless skin down to a science. Even fresh-faced, she looks smooth and sculpted - and we think we've found her trick. She reportedly uses a smoothing serum that shoppers insist is basically "Botox in a stick." As Glamour noted, the Duchess turns to Tatcha's The Serum Stick to erase the look of fine lines. The Japanese-inspired formula seals in hydration, boosts glow and glides on like a dream - all in a convenient stick you can toss in any bag.
