The shadow is there and there is not much you can do to get rid of it. Key to dealing with it is to de-emphasize the contrast between your bare skin and the shadow's edge. A tan helps immensely in this regard - either natural from the sun or by using the Jergen's Natural Glow products...which might be tough in a barracks. If you go with the tanner stick with the Jergns product, there must be other ones out there that work and don't give you an orange cast but the Jergens one is the one many of us have used and had good to great results with. Another option is to go for SHINE....it also helps to redirect attention from the shadow. But, as others have said, we are each our own worstcritic when it comes to the shadow. Wiht the exception of other sly guys the rest of the world doesn't notice it.
And still another way to handle it....shadow is just a part of the SBC look.
