L'Instant de Guerlain is a divisive brew: a complex gourmand with a refined, if vintage, character. You'll either adore its sophisticated blend of cacao and citrus, or find its old-school charm just plain 'old'.

Rebel 33 nods to Le Labo Santal 33's cult woody-leather signature but leans on a brighter citrus-spice opening and a simpler cedarwood-patchouli base, missing the creamy sandalwood-and-leather texture that made the original iconic.
