Idealist is a skin refresher that you're supposed to use under your regular moisturizer. I finished up my sample size bottle and I had to buy the regular size. It is expensive for the amount you get but remember, only one pump of the bottle is required for each application. My skin is not flaky after I use it. It has no acids in it so it is good for even sensitive skin. I took off a point because it is pricey.
