how to make a toner from the basics of a serum formula
I was making a 5% lactic serum today and thought hmmm how could I turn this into a toner? If I don’t add the xanthan gum or Siligel at the end what would you add to make this a toner instead?
water
lactic
sodium lactate
glycerin
green tea extract
*xathan gum replace with what?
