Causes Of Razor Burn
Razor burn is the general skin redness, abrasion and irritation that result from shaving. The nicks and cuts that are caused by shaving are also often referred to as “razor burn”. One of the most common causes of razor burn is using too much pressure when shaving. This creates excess friction that leads to razor burn. Other common causes include lack of sufficient skin lubrication and shaving against the “grain” of hair growth. Using after-shaves and colognes can also contribute to the problem by drying and irritating the freshly shaven skin.
