How does colour-change gloss work?
They say love is a chemical reaction, well this is one you can see. Colour changing lipsticks/gloss react with your skin’s pH to create a colour different to the original lipstick.
This colour change has everything to do with acidity (pH). The lipsticks or glosses contain dyes that act a bit like litmus paper, the acidity indicator beloved of school chemistry teachers.
Inside the lipstick, the dyes are colourless, weak acids. But lips have a higher pH than the lipstick, which triggers a chemical reaction that converts the acids into a strongly coloured compound.
The exact lipstick or gloss colour will depend on the skin’s pH, which is in turn affected by physiological factors such as physical activity and hormone fluctuations. Our underlying natural lip colour also subtly affects the final lipstick shade. #colourchange #colourchangegloss
