Razor bumps are red bumps that you see after shaving. This might be razor bumps or razor burns. Razor bumps, or folliculitis, happens quickly after shaving or when the hair is growing back. It can leave the skin inflammed, red, itchy, or with bumps.
Razor bumps are caused by contact from the razor. They can also be caused by ingrown hairs in the skin, which turn to the skin rather than out. They can cause pimple-like bumps on the skin which are very uncomfortable to the sufferer.
Razor bumps can lead to skin infections when microorganism access cuts into the skin. In this way, the folliculitis that results can only be treated by antibiotics, either oral or applied to the skin.
Razor bumps may also result from friction that is caused by the razor blade especially if a shaving cream or moisturizer is not used while shaving.
