No difference : Your skin cannot be "thinned" by shaving. A razor glides over the surface of the skin. The MOST that is can do is remove the rough dead surface of keratin protein, but this is beneficial as it leaves a fresh surface and can unclog pores. Remember to use a light non-comedogenic moisturizer with sunscreen and drink plenty of water for healthy skin.
