I've had my large bottle (400 ml) since 2010 & have used only 1/4 of it. It cleans well enough I supposed, but somehow I don't really like it. Could be because I don't feel cleansing waters clean all that well, especially if you use mineral sunblocks. Personal preferences aside, this is a refreshing cleanser, easy to use as you just need to dispense a sufficient amount on cotton wool & wipe off your makeup etc. Removes makeup well. Skin is not left dry/taut. No allergic reaction. Great for all skin types, as long as there's no allergies. It's actually also a toner, so it's a convenient 2-in-1, especially when travelling. However, I follow up with Lancome's Blanc Expert cleansing foam. I don't use heavy makeup, this 2nd step is not really necessary, but I don't like the "after feel" of the Cleansing Water, so I wash with the foam.
