Skipping the use of a daily moisturizer will most likely wreak havoc on your skin. Whether you wash your face in the shower or in the sink, apply a moisturizer immediately after drying off -- skin is porous and will absorb liquid best during this time.
Those with oily complexions may choose an oil-free moisturizer that's applied only once a day, while those with dry skin may need a product that's applied in the morning and at night. Remember, you don't have to treat all patches of skin the same. Pay attention to which areas are dry and oily, and moisturize accordingly.
