I have a tendency to always buy the wrong foundation color. I always have ghost face because I will wear an IVORY color on my TAN skin because I do not want the foundation to go to waste. 😜😜😜😜. Not no more thanks to Pigment Drops I can mix a few drops in the foundation to make it more my color! I love these pigment drops from Hard Candy because with just a few little drops I make all my wrong color foundations into new foundation without having to buy more plus it also makes foundation that is not smooth -- smoother! It also makes foundation that is not full coverage -- fuller coverage!
