i was a little concerned about the SLS in this cleanser, but so far i haven't had any bad reactions. the ph is low, it cleanses effectively and leaves my face feeling incredibly soft! very travel friendly, and i think one bottle will last me quite a while as you don't need that much product. the only downside are the size of the granules, it takes a while for all of them to "melt". what i like to do is make a little pool of water in the palm of my hand and sprinkle the cleanser on it, wait for 15 sec and lather it up. this way it creates a nice thick foam. definitely would recommend this to people with dry/sensitive skin!
