This leaves my hands soft and protected but like some other reviewers, I have noticed a difference. Even after shaking the tube, to try to mix the lotion, it was still runny. It came out a little thicker but slid off of my hand. I’m not sure if this is old stock that separated or if the formula just changed from the last time I bought it, but something is different. It also has a different scent than I recall, as well. It’s not unpleasant, just lightly lemon-y, but it is different from what I remember. The consistency and the scent are both different but it doesn’t seem to affect the efficacy.
