Gillette Skinguard Sensitive men's blade refills are the first razor cartridges with a unique skinguard between the blades to shave hair and guard skin. The skinguard reduces blade contact with the skin. Each blade refill also features 2 optimally-spaced, low cutting force blades to minimizes tug and pull, and lubrication before and after the blades to minimizes friction and shield skin from irritation.
