What are razor bumps or razor burn?

Razor bumps (pseudofolliculitis barbae, or razor burn) develop after shaving when strands of hair curl back on themselves and grow into the skin, causing irritation and pimples.

Razor bumps develop most often on the neck, but they can occur in any area that is shaved (such as the cheeks, underarms, pubic area and legs and arms).

Razor bumps occur most often in people who have tightly curled or spiral hair strands.

Using different shaving techniques can help relieve this problem.
