Razor bumps, razor burns or shaving pimples when found on the face are persistent irritation caused by shaving, medically known as pseudofolliculitis barbae. The term "pseudo" of course meaning false, "follicle" referring to hair, "itis" or inflammation and "barbae" (beard). This condition occurs on the beard area of people with curly hair or African-American men more than caucasians. They result from a hair growing out of the skin, curling around and then growing back in, causing a foreign body reaction. Appearing as tender, red, raised bumps, they can sometimes be mistaken for acne.
When pubic hairs are involved, the medical term is psuedofolliculitis pubis. The hair curls and grows back into the skin, the body's immune system sees the hair as an intruder and attacks it, resulting in red, sometimes raised inflamed areas. These red bumps can easily become infected and turn into "barber's rash," which is caused by the Staphylococcus aureus bacteria that infects the hair follicle, possibly resulting in redness, itching, and even tiny pus-filled blisters resembling acne.
You'll have less chance of getting them if you follow these
shaving tips. Another effective prevention is to just let the beard grow. Once the hairs reach a certain length, they won't grow back into the skin.
Also, shaving every other day, instead of daily, will alleviate the condition.
Razor burn or razor rash is a temporary irritation, redness or swelling of the skin. It's usually a result of dry shaving, going too fast or not using enough shave cream. Avoid hair removal in the area of the razor rash for a few days and it should go away on it's own. The best way to stop razor burn is to prevent it from happening in the first place. It's possible that while shaving you may experience a rash other than razor burn. This can be caused by allergic or other adverse reactions to the products being used. Sometimes applying a cloth soaked in milk can help calm the reaction.
Try applying a soothing, cool Aloe Vera gel to the area. The one I use has to be kept in the fridge and works great for things like this as well as a sunburn. Be careful with items containing any fragrance, as that can cause the affected area to become even more inflamed and uncomfortable.
