If you develop a rash after shaving your legs, it is likely due to irritation, which can cause tenderness, a burning or hot sensation, itchiness, and small red bumps. The rash is known as razor burn, and it can be treated with hydrocortisone, chemical exfoliants, and preventive measures to avoid future razor burn. In addition, good quality post-shave products, such as moisturizers and shaving creams, can help prevent razor burn. Over-the-counter benzoyl peroxide or hydrocortisone can also be used to treat razor bumps, which are a type of folliculitis that can occur due to ingrown hairs. Aloe vera and colloidal oatmeal are two skin-soothing topical ingredients that dermatologists recommend for razor burn. To prevent razor burn, it is important to practice good shaving habits, such as regularly exfoliating your skin, using a lubricant before shaving, and avoiding shaving against the direction of your hair.
