Refinery 29- Winky Lux
Much like everything else in makeup, it’s dye! Your skin is reacting to dye. Some dyes can be colorless, weak acids that turn into colored pigments when applied on the skin. They react differently at different pH levels. “These dyes are able to act like pH indicators, meaning the color is unique to you,” explains Winky Lux CEO Natalie Mackey. Mackey says that the ‘indicator’, or dye, is responding to the specific pH of your own lips, and that’s what determines the shade it becomes — typically pink or coral.
