• Accord — An accord is a blend of two or more aromatic materials that creates a unified, distinct impression — greater than the sum of its parts. Most fragrances are built from multiple accords.
• Ambroxan — Ambroxan is a synthetic ambergris-derived molecule that amplifies skin scent and adds a warm, woody-amber character. It appears in many of the most popular fragrances of the last two decades.
• Eau de Parfum — Eau de Parfum (EdP) contains 15–20% aromatic compounds — more than Eau de Toilette, less than pure Parfum. It offers strong longevity and projection for most situations.
• Longevity — Longevity is how long a fragrance remains detectable on skin — affected by concentration, skin type, molecular weight of ingredients, and application method.
• Oud — Oud is a dense, complex resinous material produced when certain agarwood trees are infected with mould. It's one of the most expensive natural fragrance materials and a cornerstone of Middle Eastern perfumery.
• Projection — Projection is how far a fragrance radiates from the skin — how detectable it is to others nearby. It's distinct from longevity and sillage, though all three are related.
• Sillage — Sillage is the scented trail a fragrance leaves behind you as you move through a room or space. It differs from projection and is affected by concentration, molecular weight, and environmental conditions.
• Top Notes — Top notes are the most volatile part of a fragrance — the first impression that fades within 15–30 minutes. They create the opening but rarely represent the full character.
