what is the difference between eau de toilette and eau de parfum

The main difference between eau de toilette and eau de parfum lies in their concentration and lasting power. Eau de parfum contains a higher percentage of perfume oil, typically between 15-20%, making it more intense and longer- lasting. On the other hand, eau de toilette has a lower concentration of perfume oil, usually ranging from 5-15%, resulting in a lighter and more subtle fragrance that doesn't last as long
