I have mild acne rosacea & my pores in my chin area need cleaning badly. what's an exfoliator that i can use for a reasonable price?

Not for rosacea: In general, if you have rosacea you should avoid using an exfoliator, because it could be irritating! Preferably, you should clean your skin gently with lukewarm water, wash with your fingers, and try to avoid harsh mechanical scrubbing. Non-soap cleansers with synthetic detergents (beauty bars, mild cleansing bars, many liquid facial cleansers) are better for your skin than traditional soap.
