Pure perfume, also known as parfum or extrait de parfum, is the highest concentration of fragrance in the perfume hierarchy. It typically contains between 15% to 30% fragrance oils, making it the most potent and long-lasting form of fragrance. Pure perfumes are meticulously crafted using a high concentration of essential oils, absolutes, and other aromatic ingredients, resulting in a rich and luxurious scent experience. Due to their high concentration, pure perfumes often have exceptional longevity, with fragrance notes unfolding gradually over time.
