Razor bumps are painful, itchy and often unsightly blemishes that usually are a result of shaving. They can be caused by ingrown hairs, the style of razor, the way you shave, or simply from shaving in general. There are many products on the market with similar ingredients to treat and relieve this condition.
Isopropyl alcohol is one of the safest antiseptics for topical use, according to Infection Control Today. It's a main ingredient in most razor bump treatment solutions including Tend Skin, the top-rated seller on the Ulta Beauty website. The purpose of isopropyl alcohol in razor bump treatments is to kill bacteria on and under the bump and prevent infection.
Acetylsalicylic acid in its solid form is known as aspirin, and for razor bump treatments it is diluted with water to make it a liquid form. The purpose of this ingredient is to ease inflammation of the razor bumps and reduce redness and swelling.
Glycerin dissolves into water and alcohol and is used to soften your skin. In razor bump treatments, it is used to attract moisture to the skin and to moisturize and soften the damaged skin areas. This also helps to off-set any over-drying of the skin that could have occurred with the alcohol or other ingredients.
Diglycerin is another product used for adhesion and to capture and maintain moisture and natural oils on the skin. It is formed from glycerin and has properties similar to glycerin. The purpose of diglycerin in razor bump treatments is to coat and moisturize the damaged skin areas.
