If you have very sensitive skin, you may experience a rash after shaving your underarms, otherwise known as "razor burn." This rash is characterised by redness of the skin, a burning or tingling sensation and small, raised bumps. Fortunately, there are several practical steps that you can take to treat razor burn, and reduce or completely remove its appearance.
Use Vitamin E oil directly after you shave and dry your underarms. The Vitamin E will instantly refresh your skin and slow the rash from spreading if it has already started appearing.
Apply Aloe vera to the burnt area to cool the area and promote healthy skin regeneration. If you do not have aloe on hand, tea tree oil also works well for cooling the area and promoting new skin growth.
Add more Vitamin C to your diet. Although you might not guess it, Vitamin C is an essential nutrient when it comes to skin health and nutrition. Simply taking a Vitamin C supplement or having an extra glass of Vitamin C-fortified orange juice can help stave off future rashes under your arms.
If you do not have any Aloe vera or tea tree oil, you can also treat the pain of an early rash with a hydrocortisone cream (like Neosporin) to give you instant relief.
If you have a rash that bleeds or intensifies, you may have a more serious condition than just a common case of razor burn. In these cases, it is important to see a dermatologist as soon as possible for diagnosis and to prevent infection.
