Don't over exfoilate. Your skin can't keep up with all that abrasivness! Depending on your skin type- I say oily/combin 3-4x's a week is ok. But if you have sensitized skin, only do it like once a week but gently.
Too much exfoliating with rough scrubs will hurt it long term. As good and clean as the St Ives feels after an exfoliation, IMO, The St Ives is not the best b/c of its sharp forumula. Find an exfoliant that had smooth round beads.Those won't harm your skin in the long run.
