Extrait de parfum, also called pure perfume, is the strongest and longest-lasting type of fragrance. It has the highest concentration of scent ingredients—usually between 20% and 40%—which means it smells richer and stays on your skin much longer, often all day or even overnight. Because it’s so strong, you only need a tiny amount, and it’s usually dabbed on areas like your wrists or neck. The scent develops slowly and lasts for hours, making it a great choice for special occasions or for anyone who loves a deep, powerful fragrance.
