Unfortunately, I'm not really sure how to use this product, even after seeing numerous videos and reading tutorials. I've been blessed with really clear skin, and so I rarely use foundation: the process of contouring is lost on me. I actually saw this and thought it was lipgloss until I read the card that came in the box. I tried it out (read-had my friend put it on me) and I liked it! I thought the pink would be too light for my medium skin, but the background of it virtually melds into my skin, leaving only the faint sparkle. It isn't gooey or heavy, and my skin didn't react to it (but I don't break out easily), and it didn't smell. Since I don't use luminizer, I probably wouldn't buy this on my own, but I have no objections to it.
