Eau de cologne is a light and refreshing type of fragrance with a low concentration of aromatic oils, usually around 2% to 5%. This makes it much less intense than other types like eau de parfum or eau de toilette. Eau de cologne often features bright, citrusy, and herbal notes, giving it a clean and energizing scent. Because it’s so light, the scent usually lasts only a couple of hours and may need to be reapplied throughout the day. It’s a great option for warm weather, casual settings, or for those who prefer a subtle, easy-to-wear fragrance.
