This product is described as a smile brightening lip shine. The subtle blue sheen is supposed to make your teeth appear whiter. By subtle blue sheen they mean tiny blue sparkles. I like that it has a minty scent, and makes your lips tingle. It feels very moisturizing and stays on for a long time. My only complaint is that the sparkles stick to your lips – as sparkles tend to do – and they’re hard to get rid of. I am not sure if it actually makes your teeth appear whiter, but that aside, it is a nice gloss. I’m not sure if it’s worth the extra money considering its not terribly more special than a regular gloss, but I do like it.
