Yes, this stuff is expensive, but a very very little goes a long ways and absorbs into my skin quickly. I have a very oily forehead and nose, and at the end of the day, my skin is actually less oily if I apply a bit of CADE Concentrate than if I apply nothing at all.
I suspect that this little container will last me 6 to 9 months if I can stop applying it to the backs of my very dry hands, otherwise 3 to 4 months.
When you consider that you are only spending around $6/month, it really isn't that expensive.
