It will last you a decent amount of time. If you use the right applicators and amount. In reality you need about a nickel size of foundation to evenly cover your face. If you use a foundation brush you will use even less ! Sponge applications soak up too much product and don't blend smoothly. I invested in a good foundation brush and I have found myself using much less foundation that I had used it the past. I picked my foundation brush up at Ulta !
