Difference between Eau de Toilette (EDT) and Eau de Parfum (EDP)

The main difference is the concentration of perfume oil, which will have an impact on fragrance's intensity and longevity. Eau de Parfum (EDP) has a higher oil concentration, while Eau de Toilette (EDT) has a lower concentration (5-15%) and a lighter scent. As a result, EDP is often more intense and better for evenings, while EDT is a lighter, fresher choice for daytime.
