For bacterial infections and frequent acne in areas where you shave, topical antibiotic creams like Fucidin can be used under medical guidance, as they help treat localised bacterial infections. However, they will not prevent new acne caused by shaving irritation, so it is vital to maintain proper shaving hygiene, use gentle techniques, and keep the area clean and dry. If infections or acne are recurrent or widespread, a healthcare professional should evaluate you for underlying causes and may recommend additional treatments.
