Y by Yves Saint Laurent was created to capture the spirit of youth and appeal to millennial men, giving this generation a scent that's uniquely theirs. YSL Y eau de toilette is a crisp, classic cologne with masculine top notes of white aldehydes, bergamot, and ginger over heart notes of sage, geranium, and violet leaf and a base of ambergris, incense, fir, cedar, and musk.
