Banana baking powder or translucent powders are loose powders that help you to make your makeup stay in place for a longer time. They prevent the makeup from creasing and slipping off from areas where you have folds, like eyelids or around the mouth.
Translucent or banana baking powder can also prevent your foundation from oxidizing, especially during the hot summer days. Powders absorb the oil and sebum from the skin, which then does not mix up with your foundation and turn it grey.
Translucent powder is white and can be used by people with any skin type; however, banana baking powder suits people with a whitish complexion. Both these powders can also help control the shine on the face and is the best choice for afternoons.
The skin already feels numb and dry in winters, so you do not need to apply any powder. But if you have incredibly oily skin, you should use powder so that there are no chances left for your foundation to turn grey.
