  • Preventing a tinted face Serum from oxidizing

    We are using natural botanicals that are colorful on their own and when added to this formula they create a beautiful hue. The problem is that after a week the color starts to turn/oxidize. We are using a natural preservative, along with an emulsifier and Tetrasodium Glutamate Diacetate at the recommended levels. Any suggestions would be great. Thank you!
