For £20, you can purchase a set of three tinted lip balms with super-cute tiny flowers inside, created by American brand Winky Lux.
The lip balms, which come in a gold cosmetics case, go on clear but quickly change to different pink hues, depending on the pH of your skin.
A fluorescein-based dye adjusts the colour within 60 seconds to what is supposedly your most flattering colour. Kind of like a mood ring, but for your lips!
