Razor bumps

Also called: Pseudofolliculitis barbae, Shaving bumps

Razor bumps are inflamed bumps that happen when shaved or plucked hairs grow back into the skin and trigger irritation.

At a glance

  • Razor bumps are common on the beard area, neck, jawline, underarms, and bikini line.
  • They are not always acne, even when they look like small pimples.
  • A less close shave often helps more than a stronger aftershave.

The short answer

Razor bumps are inflamed bumps caused by shaved or plucked hairs growing back into the skin.

The medical term is pseudofolliculitis barbae. It is especially common where hair is coarse, curly, closely shaved, or repeatedly irritated[1].

How to use the word

Razor bumps often appear on:

  • beard areas
  • jawline
  • neck
  • underarms
  • bikini line
  • legs

They can look like acne, but the trigger is hair re-entering the skin and creating inflammation. Reviews of pseudofolliculitis barbae treatment[2] consistently point back to shaving technique and hair-removal choices as central parts of management.

Mads's practical read

Do not answer razor bumps with a stinging aftershave and heroic pressure.

Soften the hair, use slip, shave less closely, moisturise after, and treat clogged pores separately if acne is also present. The skin does better when shaving stops being a tiny injury routine.

Common questions

Are razor bumps acne?

Not always. Razor bumps come from hairs re-entering the skin after shaving or plucking. Acne forms from clogged and inflamed follicles.

How do I prevent razor bumps?

Use less pressure, shave with the grain, avoid repeated passes, moisturise after shaving, and consider trimming instead of a very close shave.
