QUESTION: When washing my face what is best to use? Hands/paper towel/ or washcloth? I have sensitive skin.

Neither...I recommend using a PVA Smooth Skin Shammy. It is ideal for sensitive skin and not abrasive at all...being that you describe you skin as sensitive this would be perfect for you! Try Skin Rx Clinic PVA Smooth Skin reference "shammy" in search box and it will pull up.
