After Shave-and he is also a perfume, but the proportion between oils and fragrances significantly less alcohol, focusing rather on the look antiseptic. For this reason, the odor released by the application of an after-shave is not as persistent as that of a perfume. A similar situation is encountered and deodorants.

For reference, Eau de Parfum contains oil in concentrations of 8% -15% and the smell will last between 3 to 5 hours, while Eau de Toilette contains oil at a rate of 4% – 8% and the smell will take between 2 and 4 hours. Perfumes of other species have concentrations of between 15% and 30%, and can take up to 6 hours depending on the skin and are applied and clear and the amount of fragrance used.
