Exfoliating your skin is great for getting rid of dead skin on your face, or making your face look brighter. There are some certain rules to it though. One being that you should only exfoliate your skin once a week. Breaking this rule can cause irritation on your skin and make it worse and redden skin. Another one is scrubbing too hard. When you do this you can redden your skin and make it worse. You could also accidentally get rid of alive skin.
