According toStylecaster, the color-changing lipstick trend took off back in the 1970s.
Avon was one of the major makeup companies at the time to bring out color-changing lipsticks called Color Magic.
The lipstick bullets came in neon colors like yellow, green, and blue .
yet they all appeared pink upon system to the lips.
Cosmetic chemist Ni’Kita Wilson toldAllurethat the primary magical dye used in color-changing products is none other than Red 27.
“Red 27 is pH-driven.
According to BBC Science Focus, the dyes used in the products are weak acids that appear colorless.
Wilson added that the Red 27 dye remains colorless when it remains unexposed to water.
Per makeup.com, the clear, pH-reacting substance can also be mixed in with another color.
That’s how the color-changing lipsticks of the 1980s came invibrant neon colorsthat all turned pink on the lips.
The pH level can be naturally influenced by hormone and exercise levels.
What they found was intriguing for all the makeup nerds out there.
The pH-reacting lipstick applies typically as a soft pink over bare skin.
So if you’re trying to get the ultimateBarbiepink lips, it’s probably best to avoid drinking lemonade.
Of course, we don’t recommend putting soap water on your lips either (for obvious reasons).
Remember, that the dyes stay colorless until they are in contact with moisture.
All of this is taken into consideration when makeup companies are formulating pH-reacting makeup products.
And they also are tested on skin to see the intensity of the colors.”
