While your oily, shiny skin may make you want to scrub your face several times a day with harsh products and slather on acne-busting products, resist that urge. Those harsh ingredients are known to dry out your skin -- yes, even oily skin can get dried out -- which will only trigger your body to produce more oil. Products that contain salicylic acid, benzoyl peroxide and rubbing alcohol, as well as exfoliants with large or rough-edged particles such as coarse salt or pieces from crushed walnut shells, are too harsh for the face. Although oily skin can usually stand up to some ingredients that may be too irritating for dry or sensitive skin, it doesn't mean oily skin isn't sensitive to scrubbing and drying agents, and even to dyes and fragrances. Gentle products won't cause skin to become inflamed and irritated, which can lead to acne flare-ups.
