"My grandmother was always telling me 'Never cringe!,' saying it was the quickest way to age a girl. This was basically the best 'Botox' before Botox existed. Anytime she noticed me making a face, she'd remind me and eventually I became so aware of my facial movements that it became second nature to make sure I wasn't unconsciously giving myself wrinkles." —Amal Elbahnasawy, foundress of ARTISANskin
