not enough product for the price

It\’s a really nice moisturizer, it helps control my oils throughout the day, but when I got it I was shocked by how small it is, I only use two pea-sized dots of it twice a day (sometimes only once because I\’m scared of using it all too quickly) and it\’s enough to cover my face and under my jaw but not down my neck, and I\’ve only had it for a little over a month, and it\’s already over halfway gone! It\’s simply too expensive for such a small amount.
