I ordered both the olive argan butter and the unscented lotion. The butter has the heavy-duty moisturizing/smoothing power I need for my very dry skin and is still very pleasant. It penetrates very well and the effect lasts. After 10 min there is no sign of the product on the surface of my skin, and the skin feels well nourished and smooth. The smell of the olive-argan formulation is so discreet, you could say there is none.
The lotion is very nice too. It is a lighter and so, less powerful product, that is instantly absorbed and feels very pleasant.
So if you're agonizing on whether to get the lotion or the butter, don't worry any longer, they're both good products. The preference would depend on your skin type and your wallet. The butter will go a much longer way for me.
