What is the difference between eau de parfum and eau de toilette?

Eau de parfum and eau de toilette are both popular fragrance types, but they differ in concentration and longevity. Eau de parfum has a higher concentration of essential oils, making it more potent and longer-lasting on the skin. It typically contains 15-20% of fragrance oils, providing a strong and pronounced scent that lingers for hours. On the other hand, eau de toilette has a lower concentration, usually around 5-15% of fragrance oils, resulting in a lighter and more subtle aroma. While eau de toilette may not last as long as eau de parfum, it is often worn for its refreshing and daily wear-friendly nature. The choice between the two ultimately depends on personal preference and desired intensity of fragrance.
