The length of time it takes for razor burn to go away varies depending on severity and skin type. Normally, razor burn disappears in a short amount of time. This is typically within a few hours to a couple of days; however, there are ways to help razor burn go away faster.
It is important not to shave again until razor burn is completely gone to avoid irritating the skin even further. Aloe vera or other soothing creams and oils help soothe the skin, and tea tree oil can be used as well, notes Adrian Bryant for NowLoss.com. After shaving, if redness or bumps are present, apply a warm washcloth to the skin for a few minutes to relieve irritation.
Razor burn and bumps occur when excessive pressure or a dull razor is used. The skin is delicate, and scraping an object against it can cause irritation. Also, shaving against the direction of hair growth can lead to razor burn. Shaving with a dirty or old razor can also carry bacteria that inflames the skin when it is shaved. It is best to use a clean sharp razor when shaving to avoid skin inflammation and to shave in the direction of hair growth, avoiding any ingrown hairs.
