Dull Complexion, what is it?
Dehydrated skin doesn't have enough water in the dermis, which causes premature fine lines and a dull complexion. In skin care, dullness essentially refers to a lack of radiance or an inability to reflect light well. Dull skin may appear dry, patchy, ashy, or dull. Additionally, dullness is often accompanied by uneven skin texture because textured skin is less able to reflect light evenly.
