Eau de toilette (EDT) is a light and refreshing type of fragrance that typically contains a lower concentration of aromatic oils, usually around 5% to 15%. This makes it less intense than eau de parfum, resulting in a more subtle scent that is ideal for everyday wear. EDT fragrances often have a bright and lively opening, with top notes that are more prominent and fleeting, while the overall scent tends to fade after 3 to 5 hours.
