Query: A couple of things...

First, like other reviewers have stated, it has a lotion-like consistency and therefore the dropper system doesn't work well; a pump bottle would be better. I'm guessing I will have to water it down at some point to get it out. Secondly, it leaves a sticky residue on my skin, even after 30 minutes. I guess if you are putting another product on top of it, or even make-up, the sticky may go away. I don't, so it doesn't. After this bottle is gone I will switch to another product.
