Perfume oils are concentrated fragrance products made from essential oils and aroma compounds. Unlike traditional perfumes, which contain alcohol and water, perfume oils are typically oil-based, making them longer-lasting and more intense. They are often applied directly to the skin, allowing the scent to blend with body chemistry for a unique fragrance experience. These oils come in various scents, ranging from floral to woody, and can be used alone or layered for a personalized aroma. Many people prefer perfume oils for their skin-friendly properties, as they usually contain fewer irritants compared to alcohol-based perfumes. Popular brands include Jo Malone and Dior.
