Some skincare products that prevent and treat razor bumps contain acetylsalicylic acid, which is more commonly known as aspirin, points out the cosmetic scientists at BeautyBrains. A study was conducted on the benefits of topical acetylsalicylic acid by researchers at the University of Bonn in Germany, which indicated a 92 percent to 96 percent decrease in pain when applied topically to inflamed skin. There are only a handful of consumer products for razor bumps that contain stabilized aspirin, says skincare expert Paula Begoun, who adds that it's possible to make a similar remedy at home.

Crush up one or two uncoated aspirin tablets. Dissolve the crushed aspirin in 1/4 cup of tap or distilled water.

Add four or five drops of glycerin into the aspirin and water. The mixture should be viscous enough so it clings to your skin without running off, but not as thick as a liquid cleanser. Glycerin is a thickening agent that you can purchase at most drugstores, Begoun states.

Apply the aspirin toner to freshly-shaved skin -- face, bikini line, underarms and legs -- with your fingers or a cotton ball. If you intend to put on moisturizer, wait until the aspirin solution is fully absorbed into the skin, Begoun advises.
