Vertus Bengal is a unisex aroma that people of both genders enjoy. Anyone who likes earthy fragrances can wear this cologne. A: Because Vertus Bengal is an EDP with a high concentration of fragrance oil, it lasts for six to eight hours in most conditions. Certain conditions may cause the scent to fade prematurely. Application method, environmental factors and body chemistry all play a role in how long the fragrance lasts. Exposure to extreme heat or incompatible body chemistry may negatively impact longevity, but you can often compensate by experimenting with alternative application techniques. Applying the fragrance to clothing or walking through fragrance are two techniques that often work well.
