I guess I didn't deliver what I meant clearly. For some people, the fragrance is the added benefits itself. The growth of aromatherapy, perfume industry and etc shows the significance of fragrance. Its the same for perfume, you don't normally smell it after awhile, Its due to brain not sending the same signals over and over again. There are people who prefer fragranced product over odourless products. Just like some people prefer makeup, and some prefer their bare face. Makeup in general have no added benefits to the skin, and back in days, some powder contains poison. Cheap makeup these days can be risky too, does that means that there's no plus point for makeup?
The idea behind these topics is to understand that it maybe worthless for you, but it maybe the thing someone loved. There's no right or wrong answer. I am not trying to argue anything, just wanted to provide a view from different angle.
