Definition
Layering is applying two or more fragrances together, typically by spraying one on skin and a second over it, or applying each to different body areas. The resulting combined accord is influenced by each fragrance's volatility curve, concentration, and dominant materials. Several niche houses market their collections with explicit layering recommendations (Basenotes wiki, accessed 2026-05-27).
Layering differs from custom blending: the fragrances remain separate formulas applied simultaneously, rather than being combined in a single bottle before application. The result changes throughout the day as each component evolves on skin independently.
In practice
Effective layering strategies include: combining a skin-close musky base fragrance with a more assertive floral or aromatic on top; layering a diffusive projection fragrance with a soft intimate-skin scent; or using an unscented body lotion as a base before applying fragrance to extend longevity.
Niche brands including Le Labo, Escentric Molecules, and Maison Margiela have published official layering guides. The practice is particularly common in Arabic perfumery traditions, where multiple oud and mukhallat materials are worn simultaneously as a social and cultural expression (Fragrantica, accessed 2026-05-27).
