I just saw these drops on someone's YouTube monthly favorites and am really excited about them. I'm going to stop by Sephora on Monday to check them out.
I saw a twitter conversation hour (I don't know what to call Twitter stuff) about it, and it sounds really interesting! I'd really like to try it. I like that it can be mixed with just about any product. I could use it with matte primer in the summer, and my moisturizer in the winter! Helps kill a few products with one stone.
