One of the opening scenes is set in the protagonist’s bathroom. He’s standing alone in front of the mirror, but he’s looking at the other side of the counter, where many beauty products are. A close-up on this side shows us that it used to be Helen’s, his dead wife.
In the central part of the counter I’ve spotted a bottle of Kiehl’s Creme de Corps, Marvis toothpaste in Cinnamon Mint and some Jo Malone perfumes.
There are other products around the washbasin, among which a small bottle of L’Occitane Verveine shower gel (old packaging) and a NARS lipstick.
Jack (Keanu Reeves) and Lindsay (Winona Ryder) are attending a wedding neither of them is happy to attend, but they find a connection between them. At the ceremony, for example, they comment on the minister, a friend of the newlyweds. Jack asks if he’s wearing make-up and Lindsay confirms it by namechecking one product Levy always uses.
It’s the Radiant Creamy 
There’s a huge bottle of perfume among the twelve Christmas presents that Nelson (Keanu Revees) gives Sara. It’s named after her and it’s a “custom-made fragrance capturing that special something a woman leaves on a man.”
It’s actually a factice of Aimez-Moi (Love Me in French, how apt) by Caron. Created by Dominique Ropion and launched in 1996, it has notes of violet, star anise and mint.
