If there were a dictionary devoted to beauty, listed under the word 'classic' you'd find Guerlain. This purveyor of luxury fragrance, makeup, and skincare has consistently defined—and redefined—our standards of beauty for over 175 years. Since 1828, Guerlain has guided us through a remarkable series of firsts, including industry standards like lipstick, eyeliner, mascara, and scientifically based skincare.
