The idea works on the colour wheel, where by pink and blue are on opposite sides. This means that the blue on bunk lips turns a lovely berry colour.
This does not look blue on lips, it is a lovely hint of colour that lasts for a a few hours. I find the impact looks best after 15 minutes of application.
The constancy is similar to a lip balm, slightly tackier. It tingles on the lips slightly, similar in feel to using a mint lip balm.
It claims that it will also make teeth look whiter. I cannot comment on this, as I can't really tell, but no harm if it does help, no one wants teeth to look discoloured!
Hello Sailor is different many of the other Lipstick Queen Products I own, but is a nice addition to my collection. The most similar product to it, that I own would be the Chinatown Lipgloss Pencil in Mystery, however this is already a berry colour.
