Shaving often brings discomfort, whether it’s a cut, nick, or irritation from a razor with many blades, or redness that shows up after you finish. Shaving can sometimes leave more than just smooth skin—it may lead to razor burns and bumps. Here’s what you should know about the differences between them and how to prevent both.
Understanding the Difference Between Razor Burn and Razor Bumps
Although the terms may sound similar, razor burn and razor bumps are distinct conditions. Learn more from the Cleveland Clinic and dermatologist Sandra Lee, MD:
Razor Burn
What it is: The redness, discomfort, and itchy irritation that can appear within an hour or two after shaving—sometimes even in just a few minutes.
Medical term: Irritant contact dermatitis
Causes: Shaving too fast, using a blunt blade, dry shaving, shaving against the grain—any form of skin irritation caused by a physical or chemical irritant (such as shaving cream).
Appearance: Red, patchy rash on the skin
Razor Bumps
What it is: Small inflamed lumps that develop when shaved hair grows back but gets trapped beneath the skin’s surface.
Medical term: Pseudofolliculitis barbae
Causes: Using a blunt razor, stretching the skin while shaving, or shaving against the grain
Appearance: Tiny pimple-like bumps
How to prevent razor burn and razor bumps
Some individuals are more susceptible to razor burn and bumps, especially those with acne or dry, sensitive skin. However, there are effective ways to prevent both issues. Here are some helpful recommendations from the Cleveland Clinic, Lee, and the American Academy of Dermatology:
Moisturize your skin before and after shaving
Regularly exfoliate to avoid hair getting trapped beneath the skin
Use a lubricant such as shaving cream, gel, conditioner, or soap to form a protective layer between the skin and razor
Shave when your hair is softened, like after a warm shower or applying a damp, warm washcloth to your skin, which helps the hair swell and reduces the risk of it curving back into the skin
Shave in the direction of hair growth
Use short, gentle strokes while shaving
Rinse your razor after every few strokes
Finish with a cool water rinse or a cool, damp washcloth for your skin
Change razors or blades often, especially before they become dull or rusted
Clean and dry your razor after each use, and store it in a dry place to prevent bacterial growth
Finally, take your time when shaving. Even spending just an extra minute or two could spare you from irritation and discomfort later on.
