Can someone explain to me why Maybelline is so stingy and only put 20ml into this Perfector? Like it literally says that it's a 4 in 1 product so you can use it all over your face. Most foundations come with 30 ml so I don't know which marketing genius decided on this amount...the price is also too much in my opinion for the amount of product you get. It retails for 15€. I haven't used it so much and already more than 1/4 are gone...makeup
