Demi-Jour was originally launched by the historic perfume house Houbigant in 1933 as an eau de cologne, but it was revived and relaunched in 1987–1988 as a modern floral-aldehyde women's fragrance under Houbigant/Dana. The scent is described as a soft, powdery floral with notes including:Top: Aldehydes, violet, bergamot Middle: Iris, heliotrope, ylang-ylang, rose, jasmine, lily-of-the-valley Base: Sandalwood, musk, oakmoss, cedarReviewers often call it delightfully powdery, warm yet fresh, with a cozy violet-rose-musk vibe—reminiscent of classic powdery florals like a softer L'Heure Bleue or something timeless and elegant for bedtime or everyday wear.
