While shaving. Always use a sharp blade. A dull blade is the most common cause of skin irritation. It causes cuts and abrasions as it catches skin along with the hairs.
 
Rinse the blade often in hot water when shaving and use slow short strokes.
 
Always shave in the direction of hair growth.  Shaving ‘against the grain’ can cause redness, rashes, razor burn and ingrown hairs. Leave the bits where the stubble is toughest – usually under the nose and around the chin – until last. That way they’ll have had more time to soften.
 
Don´t apply too much pressure.  The razor should glide across the skin without dragging.
