This is one of the commonest mistakes. Applying makeup on dry skin can affect your face, causing dryness and flakiness. You can avoid dryness and flakiness by exfoliating your skin once a week or, find alternative ways, like moisturizing and cleansing, to get rid of the dead skin cells. When your face is already moist, then you can go ahead and apply your makeup. The results will be amazing. Never, ever, apply makeup on a dry face without moisturizing first.
