I have a question about using the color. There is D&C Red27 that changes the color. I want to ask if I put it in the lip formula, what should I do to make the lip color light and then apply it to a dark color? There is no water in the formula.
Inquire: Use D&C Red27 color in the formula. The lip gloss has changed color and melted into a stick. After leaving it for 2-3 months, the color will fade. What is the cause?
