  Colour changing product

  Posted by Anonymous on January 4, 2020 at 9:38 pm

  Hi, i’m looking to create a cosmetic product that changes colour when exposed to the heat from sunlight, is there a pigment that safe on the skin that i can use? Would i have to formulate a thermal pigment myself?

  Thanks!

  I think you are combining two different ideas. There are some pigments that would be UV sensitive (so color changing in the sun) or thermal. The heat from your body would likely change the product color before the heat from the sun would.
  There are also products that change color based on pH like bil says. Those can be used on skin if done carefully, I’m not sure about the others.
