Not all perfumes are created equal — and the difference often comes down to concentration. The concentration of fragrance oil determines how intense, long-lasting, and ultimately how luxurious a scent feels on the skin. Parfum (Extrait de Parfum) — 20–40% concentrationThe most potent and long-lasting form of fragrance. A single application can last 8–12 hours or more. Ideal for special occasions and evening wear. The richest and most expensive option. Eau de Parfum (EDP) — 15–20% concentrationA popular choice for everyday luxury. Lasts 6–8 hours and offers a strong, full scent profile. The sweet spot between intensity and wearability. Eau de Toilette (EDT) — 5–15% concentrationLighter and fresher, lasting around 4–6 hours. Perfect for daytime use and warmer climates. A great entry point into a fragrance house. Eau de Cologne (EDC) — 2–4% concentrationThe lightest concentration, typically lasting 2–3 hours. Refreshing and casual, often used as a body splash or post-shower spritz. When choosing your next fragrance, consider the occasion, season, and how long you need the scent to last. For a truly luxurious experience, Parfum or EDP concentrations deliver unmatched depth and longevity.
