Aside from the uncomfortable burning sensation, razor irritation is often accompanied by small bumps called pseudofolliculitis barbae, which aren't dangerous and fade along with the redness and irritation within a few days. Use the proper technique and razor to prevent razor burn, and treat it with a variety of products and home remedies.
