What is the difference between Perfume, Eau de Parfum, Toilette, and Cologne?
The concentration of oils in the fragrance is called juice. Perfume or parfum has the highest concentration of juice, next would be Eau de Parfum, then Toilette, and Cologne. The higher the concentration the stronger it smells and longer it will last. In Men’s fragrances, Toilette and Cologne are interchangeable and After Shave has the least amount of oils.
